Title: Introducing the mind blowing EVS Ground Enhancers!
Post by: Ric Schultz on 5 Nov 2010, 02:43 am
What can I say?  You just have to hear them!  $30 for one pair or $25 for two or more pairs.  They mount on the ground terminals of your speakers and amps and we will soon have versions with RCA jacks that mount on line level devices. 

So, what do they do?  Make the sound much better and in most every way.  The sound is bigger, more transparent, more details, better imaging, larger soundstage, better bass, better decay, more air, better dynamic shading, blacker backround, etc.....its like getting a much better amp or speakers.....for extremely very little money.

What are they and how do they work?  They are simply a tuned OFC litz wire loop. How they work is a mystery.  They seem to act as a low impedance ground point that allows more detail and kills noise.

How universal are they? So far, everyone on every type of speaker has been impressed with the results.

How do they differ from the Audioprism Ground Contol?  Very similar in function.  We use twice as much area of wire, different gauge wire and a different type of litz.  We also terminate our device with an 18 gauge PCOCC copper wire instead of a spade or banana plug (we will have options for every type of connector imaginable).  Our devices cost much less at one sixth to one tenth the price.  How do they compare sonically?  We will let the public decide.  Stay tuned for many A/Bs.

There is really nothing else that does this function.  You can have a million dollar stereo with every tweak out there and then when you add the Ground Enhancers they will still do their magic.

These things are so inexpensive and so universal and so effective that every audiophile will want them on their system.  We will do our best to keep up with the demand, but they are now in stock and shipping immediately.  There are already reviews on Audiogon and AudioAsylum and you will see hundreds more within weeks. There will be some times where we get backodered so if you want to be one of the first and not wait then order now.

We are selling these thangs with 30 day money back gaurantee.  However, You will not send them back!!!!!

Please see our website for more details.  There will be a ton of information there.  You are only seeing the tip of the iceberg.  There will be instructions, pictures of them mounted on amps and speakers, links to reviews and discussion forums, customer comments, etc.

Sounds to good to be true?  All I can say is...If you don't get them now, you will eventually.  These things are amazing!!!!  I think the hardest thing to get is that these things work when there seems to be no normal explaination.  I struggled with this myself and so did one my beta testers.  He kept asking me "How could it do this?"  A frickin piece of wire hanging off the ground terminal?  I mean come on! Well, the ears hear what the mind fails to get.  And what your ears will hear will bring a smile on your face.  Money back gaurantee.....what have you got to lose?  In fact, until the end of the month, I will pay shipping both ways if you return them.....not one cent lost!

We will have paypal buttons on the site in a few weeks but for now you can just paypal me the money directly.  ricevs@comcast is my paypal address and you can paypal me direct or you can send me your email address and I will send you a paypal invoice.  Please let me know whether you want the straights or hooked ones (or combo).

"However, using them at the preamp and source will also enhance the sound."

How do you hook them up to the preamp or source?  Somehow to the RCA jack ground or the power cord ground?  :scratch:
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: Ric Schultz on 5 Nov 2010, 05:47 am
We will have versions with RCA jacks installed.  You can simply plug them into an unused rca jack on a source or preamp.  We will also have XLR versions so if you were using the RCA ins/outs on a source/pre you could plug these into the XLR ins/outputs. You can also solder them inside a component directly to the input/output jacks or to ground busses, speaker posts, etc.   We will have tons of pics on the website showing them in various uses.  Very versatile.

You do not want to use these on an AC ground.  These are for line and speaker level grounds.

This technology works. I've had electron pools on my speakers for 2 years. And Bud brought me an RCA implementation which i put on my DAC this summer.

Nice to see a more reasonably priced implementation. At these prices it is a no-brainer.

If anyone wants to check out some of the early experiences check out the origin. http://www.diyaudio.com/forums/parts/102180-groundside-electrons.html

got mine yesterday and I'm impressed.
More detail ,bass.texture,imaging ,soundstage has improved with no break in . Had to use the string to tie the speaker cable because I did notice ringing. But that has been fixed

Post by: Brian Cheney on 9 Nov 2010, 03:35 am
Thanks to a rather fanatical and dedicated customer, I have been experimenting with Ric's GE devices for several weeks.

I will not speculate on how they work, and some of the explanations offered elsewhere appear unscientific at best.  I will point out that they are the proper length to function as a microwave antenna, and are attached to crossover filter (and therefore amplifier) common ground.  Draw your own conclusions.

I used them with a custom pair of our RM V60 speakers which had Bybee speaker filters on each driver terminal, a total of 14 small and six large Bybee's per side.  The Bybee's did not sound good (compressing and congesting the music) when first installed, but since the customer claimed they require 400hrs breakin, and was willing to wait, I obliged.  After a month on a sweep generator, the speakers with the Bybees sounded much better, more transparent and dynamic than a control pair without the Bybee's.  Adding Ric's devices improved matters noticably, however.  In order to avoid terminology straight from the Audiophile Cliche Directory, I will stop at that.

In my speakers, the GE devices worked best as a pair, both connected in parallel to the neg. terminal of the tweeter, after the crossover.  Adding extra ones elsewhere, including midrange, bass, and subbass terminals, or on my amplifier, clouded up the sound and took away much of the advantage gained from their use. YMMV.

I don't know whether the improvements I heard were from the Bybees, the GE devices, or the combination of the two, but the improvement wrought by their use really impressed me.  I intend to add GE devices to all my speakers, and will work out something with Ric to keep the added cost down.

Two pair of Ric's devices cost $50.  The full set of Bybees run over $1200.  You decide what you want to spend.  I give both a big thumbs up.

I had Bybees on my 2 speakers, but the dingos ate them before I got a chance to hear how they affected the sound...
http://www.youtube.com/watch?v=ghCTZF61ey0
Seriously, though, I'll be very interested to hear your report of their effect, Robin, especially in comparison with the  GE devices. I'd also like to hear a comparison between Ric's and the originals sold by Audio Prism which although much more expensive are the originals and still vastly cheaper than Bybees.

I don't know whether the improvements I heard were from the Bybees, the GE devices, or the combination of the two,

From your post, I'm not clear if you tried the GE devices in your non-bybee speakers, presumably only on tweeter negative terminal.  If you have tried that, how was the effect without Bybee? 

I also presume you tried the GE device both before and after crossover and decided they work best after the crossover?  This would mean we could elect to open up our speaker and directly add the GE device to Tweeter's neg terminal instead of adding to external binding posts...

I do have 4 pairs of Ric's GE devices on order for my bi-amped system, for both speakers and amps, but I need to figure out where exactly I will put them.

One thing I've always loved about Ric's operations is how reasonable the prices are compared to others and the return policy.  Even if these things do nothing, no big loss  :thumb:

Well maybe "acclimate" would be a better word to use for your delicate sensibilties Jason.  :lol:   
 
While all I had to go by were other reported reactions which most bring up an adjustment (break-in) time, I'm finding the clarity gains and heightened soundstage to be fairly immediate. In fact, it was within the 1st 10 minutes that I knew these Enhancers were keepers. I'm also finding substantial sound stage improvements to my center channel and rear channel loudspeakers also. I think Ric won't be getting too many returns from those who made the move to try these little tweeks. If anything, I'll be looking forward to Ric's introduction of the RCA Ground Enhancers.

Sorry guys for taking so long to get them out.  I knew they would be popular but did not estimate how many initial orders I would get and the extra time taking all the orders and training people.  All orders taken through the 11th will be shipped by Monday.  Many going out everyday.

Just put the info online for the RCA and XLR versions (I know all the pics suck...will have some better ones soon....in fact, you can submit your own photos and if I use it I will give you 25% off the next order.....I have only so much time!).  I should have the info for the stereo phone connectors next week (for use on the output of headphone amps....many have parallel outputs).  The RCA versions are kinda cool.....I am using the Telos RCA shields.....so you get shielding and Enhancing. 

Then after that I will have both solid and stackable bananas (some speakers like Maggies, some Vandersteens, etc. only have banana holes, so we must fill those holes).   Then lastly I will have spades.....as the hooked versions can be used spade like now.

Well I've had my Ground Enhancers on for 24 solid hours now and their contributions haven't faded in the least during the system(and my) "acclimation" period. I find the benefits to quite dramatic in my system which is already heavily loaded with power, signal, and other tweek conditioning. The sound stage expansion is likened to my Acoustic Revive RR-77, only greater and more importantly comes with the inner clarity that really accounts for this depth perception of the sound stage.
 
While I hadn't actually noticed any "ringing" that's said to be caused from the long wire lead, I did find it benefitial to use the included string that I attached from the Enhancer's tip to my speaker cable to add a very slight tension to them.
 
Having already installed the Acoustic Revive RGC-24 Ground Conditioner to my Sunfire processor for the last year now, I can already attest to the benefits of individual component grounding units. But at $450 each, it's definitely not an attractive avenue to follow for each system component let alone just 1.  :roll:  So when something as cost effective as Ric's RCA version of the Ground Enhancer for only $25 ($22.50 for more than 1) comes along, this has me looking over my components. I will most likely be ordering 6 more Enhancers (w/banana's) for the 6 channels on my Butler tube hybrid amps. I really wish I could find a spot on my Havana tube Dac for one but the only unused connections are the Toslink & USB.  :?  Then I have some unused RCA outputs available on my DirecTv HD DVR?  :o   I might just try one more hook Enhancer for the ground connection on my BPT balanced power conditioner?  :dunno: You just don't know til you try(unless you're an individual who already knows everything[you know who you are], I am not that individual).  8)

Jason, I can only talk about my system but by putting these little tinnie weenie wire "antennas" on the negative terminals only of my Lorelei's, it has enabled me to utilze full power w/o listening fatigue. While Dave's UberBuss did much to get me there, these little gems have got me over the bump as far as what I can do and where I can do with my computer audio. I have literally no "listener's fatigue" limit now and that's something I have always struggled with because of the excess dynamics that my system carries. The fact that this little wire has done this blows my mind,,, and puts a huge smile on my face.  :D
 
Now maybe others won't have such an impact that I have had, I can only speak for my own personal situation. Of course I now want to try them out elsewhere but trust me when I say I really have no need to as I couldn't be happier being where I presently am with my sound stage.  :thumb:

Hi guys,

Well, I just received my two pairs of ground enhancers 3 hours ago and have been listening.  I put one pair on my amp and the other on my speaker terminals negative post.  Color me amazed, but instant change.... but what are they doing...?

Seems more grunge has gone (didn't think I had that much...?) allowing you to hear more inner detail.  Everything sounds more vibrant and decisive with better atmospherics.  The sound stage appears to be a touch more forward and instruments are more vivid.... it appears a touch brighter.... which may be a problem for folks with a bright balance.... but that's just in my system...?  Better separation and imaging and cleaner bass. 

All these things are subtle, but very noticeable and worthwhile.... I appear to be happy with the improvement, so they wont be going back.... thanks Ric.  A no-brainer at the price.   :thumb:

To our friend who likes to use phrases from my homeland.... there's no placebo going on here mate.... or maybe its just the first weekend Guinness taking effect early...?   :lol:

You have actually just started the ~acclimation~ process, I'm willing to bet you'll see some taming take place as time goes on. I've been playing my system 24/7 for 2 days now, mainly cuz I've been waiting for the exhilaration to wear off but just the opposite has been happening. That makes me very very happy for the long term. I hope you'll have the same reaction in the next day or so.  :thumb:

Ric finally emailed me back and said to try it on both sides and see which sound better

What if the phase is inverted? Would you put them on the positive terminals? 



I tried them both ways
I get results on the negative side of the speaker terminal. Darker background ,cleaner sound ,tighter bass and more detail. The other side the music was harsh and in your face.

Kant... "No mans knowledge goes beyond his experience".  I can't, and actually don't have a need to explain how these things work.... but they do. :scratch:  There are far more 'yet-to-be-known' things that influence Mankind than things we are actually aware of.... that's why we have such a long way to go.... thinking we know, just slows us down.  :oops:

Listened last night and the thing that came to mind was these enhancers have a similar effect as going from a long speaker cable to a very short one?  Its like the cable losses are reduced?   Similar effect to when I heard my first pair of active speakers?

Whatever.... there is definitely more detail and nuances and what appears to be more warmth on acoustic guitar etc.  These are better for listening at lower levels and still getting a satisfying picture.  I wonder if these things burn in.... being a "passive?" component...?

If anyone really knows.... I would appreciate knowing if cutting down the length of the pigtail is a problem.... being as these things are supposedly a tuned design...?

I believe these will remain a permanent part of my system.  :thumb:

Why would you even consider messing with them? They are only a few inches long to begin with.  :lol:  But I would think the tuning aspect has everything to do with their construction and messing with them would be the last thing you'd want to do.  :dunno:

Mailman dropped me some today and within seconds of putting them on my speakers everything sounded....BETTER!!!!
Noticeably so in fact, more depth for one, the music just comes from the whole side of the room where my speakers are, its crisp, clear as a bell and just kind of out in the room. Do you guys remember Evan? I asked him if he had heard these or tried them and should I get some and his response was one word..."YES". I must thank him and the others who have enjoyed hearing what I''m now hearing and were open to this new idea/concept/gadget/thingamabob and posted about it. 

Whatever the reason is, Whatever the science is, or is not, these little babies improve the music and thats what its all about for me. When you guys figure out what makes these work let me know, in the mean time I'll be changing CD's. :thumb: :thumb: :thumb: :thumb: :thumb:

Once my order arrives, I will hopefully be using them on my Audio Nirvana full range drivers. And they will be driven by a current source First Watt F2, so I can report on how they work with these unique amps. I've also got other more conventional amps that I will pair these with and will try them on my HornShoppe horns as well.

I've been curious as well regarding the EVS Ground Enhancers and will either try it via the diy recipe route or pick up a couple of pairs.

Am curious about another aspect - that is how much of a role we are playing in this?

I know I'm going down the psycho-acoustic rabbit-hole, but nontheless....

curious about what those of you have used them would say, in case you have wondered the same?

Thanks.... I read the DIY site and it appears most of those guys are soldering the litz loops directly to a spade.... so it doesn't sound like it would be a problem?  The "tuning" seems to be in the litz type, length and the dielectric specs...?

I have GE's on both ends of my speaker cables.  My Hawthorne Sterling Trio's have their Augie bass drivers (same principle as subs) driven by Rythmic's which take their high-level feed using an 18" speaker cable directly from the speaker binding posts where the last GE is positioned.  There is a definite improvement in the quality of the bass.  Seems I may need to try another pair of GE's mounted directly to the Rythmic's too.... oh no, here comes the madness again....!   :roll:

I wondered the same thing, I was very skeptical, but the results I heard were immediate and obvious. I have 3 CD's I always play first when making a change so I have some point of reference and playback of those 3 CD's was enhanced immediately. Its honestly quite surprising to me, I figured I'd hear maybe a touch more clarity as I currently have...maybe...the effects were obvious. I connected them and sat down to listen and noticed changes for the better right away. I'd love to know why??

Not meant to be a goad, nor meant to make anyone defensive. And definitely not about the "Quantum Engima."

There has been universally positive feedback about the Ground Enhancers, even from those going into the 'buy' as skeptical.

Since you are discussing what you have heard in your auditions, I'm curious to hear from those that might have reflected on the whys from your end of the interface.

Regarding the above query; the "whys" are of course facinating but to judge from past experience, this can quickly lead to a face-off and get very heated. Perhaps more interesting would be those who hear no difference or a negative one. Just a suggestion...I have a nice system so I will certainly chime in when I get these.

The hooked ones might have worked better, especially if you get the reported ringing. Less wire lead would be benefitial in that regard I would imagine. I put some string tension on mine anyways.

I ordered two pairs for the pair of hi and low binding posts on my SP Tech Revelations.  The Aether Magic Boxes are driving these speakers from the Revs Mundorf-based crossover boxes, and the MB's gave me significant improvement in timing and dynamics.  It will be interesting to hear what the GE's do, if anything.

Not to pile on to David's post, or to doubt Ric's claims......but...I will put my $.02 in and remind folks that immediate "improvements" and long-term ones are sometimes quite different.  Often when we add or change something there is excitement in the change (assuming it's not muddy or dull), even something as benign as .5db gain (we tend to like things that make out system a little louder at the same volume).  All I ask is that we revisit the day one excitement and change a few days later and report back.   if it's still just as rewarding sonically then we have a winner!!  OK, off my soapbox.  :)

I only tried a couple of songs.  Did not notice anything but will listen for it as I play it more.  It is probably as far down as a hooked one would be and it probably bent slightly in the tightening process.

I couldn't agree more Ted. That's why I held off a few days, just to see of the "acclimation period" would somehow diminish my impressions. It's been going on 4 days now with my system running 24/7 and,,, well I'll stand by what I've already had to say.  :D

Thanks, Shep.

Wanted to hear from those with a positive experience, but if that will lead to others creating a "face-off", I voluntarily bow out on the question. Can understand why some, would therefore not want to post their "reflections."

Will keep abreast on the posts here and hopefully can form my own reflections once they are in-system.

Good advice that, about prudence. I still vividly remember that ancient tweak with the green felt pen. I treated about 100 cd's very compulsively and was sure I heard a difference. I still have them and I absolutely cannot hear whatever that was supposed to do. If this works out to relative unanimity, it will be a milestone (not a Shakti stone!) and one for the books. I sure hope so.

Post by: bradmorris1 on 20 Nov 2010, 07:46 pm
In the last 10 years of my devotion to audio as a hobby there have been two moments of major gestalt shift.  The first was when I inserted the EE Minimax BBA tube buffer into my playback chain.  This was the first time that cd listening became pleasurable.  Listener fatigue died for me that day.  It was a holy grail moment.

The second gestalt shift occurred last week with the insertion of the mind blowing EVS Ground Enhancers.  I'm not going to repeat everything that has been written above but it is all true.  What I will state however is that for the first time in over 30 years in this hobby, especially as it relates to cds, I do not have to focus on the lyrics of a song in order to understand and enjoy them.  The gestalt shift is that the story of the songs through the lyrics now comes and grabs me even if I was thinking I would just be grooving to the tune.

 For example, I love the new Graham Parker cd Imaginary Television for the music but listening to it again last week with the GEs I was pulled into Graham's travails on the ski slopes in the song Snowgun.  I was right on the chairlift with him looking down on the slopes.  Before the GEs I had no idea what that song was about.  I heard the words but never HEARD the words.

What's happening?  I have no idea but this purchase has been my single greatest bang for the buck investement in audio since I purchased my first pair of Advent Large speakers in 1971.  If you look up no brainer in the dectionary you will see a picture of the EVS Ground Enhancers.

I think I'd qualify as an unbeliever  :D

Seriously, though, as an engineer I need to know certain things. Number one on my list is: 'how do you "tune" something if you don't know how it works and have no parameters to work with?'. What is it tuned to? Don't flame me or call me the guy who knows everything, just answer that one simple question. If I get a response that makes any sense at all, I might even try a pair, but so far I fail to be convinced.

And I do happen to know a lot about grounding and ground planes, it is how I used to earn my living, hence my elevated level of skepticism.

Its actually very simple to create things you don't understand... the process is called cause and effect.  You make a change in a system, any change and you note the result or effect.  You then make another change and note the result.... is it better or worse...?  This process continues as you refine the product.  Once you get tired of making change or are happy.... you have a finished product.  Its an improvement, but you don't always know why.   :scratch:

Many scientific advances happened this way.... we figured out the theory much later after seeing the results.... well, pulled one out of our butts anywhere...! :oops:

Not sure how much cred I have, but I am very familiar with the term "bollocks" and used to be an engineer in a past life.  :lol:

FYI:

After listening to a lot of material I'm familiar with, I've just had to finally change out my amp rectifier for a 'slightly' duller/warmer one.  I've worked long and hard to achieve a very neutral system on most material, but these enhancers seem to just push it very slightly into the brighter side of neutral as I mentioned earlier.... in my system anyway.  I was hoping that would go away with "burning in?", but it doesn't seem to have.

Having said that, I am hearing micro details that simply weren't there before the enhancers and it just sounds more realistic... so I'm still happy.

owenmd....I share the same thing, for a few hours last night the brightness was a bit much-not horribly too bright but close- today things seem to have calmed down alot. I have had continuous music playing since yesterday when I put these into play and about an hour after I started I did notice even more detail as if they opened up, broke in a bit, settled or whatever you want to call it. Last night the sound got bright, really bright and today its much better....interesting for sure, a do dad the size of a small firecracker that has no apparent reason for working seems to be doing just that. :thumb: :thumb: :thumb: :thumb: :thumb:

   Taking this theory a bit further is this not a ground plane ? Is it the tuning of such the main factor or is it the ground plane itself ? If its frequency would a tuning fork work ?

It's absolutely like $30 bought me a new system and a great one at that.

Hi Eclein,

Are you saying that the increased brightness you mentioned earlier has now gone...?
I've run on and off over the weekend and it still seems a little "strident" and bright to me.... although the general improvements are impressive.  Unlike some folk, I've not found I can run louder without fatigue, but it does sound much better at lower levels.... better for the old ears mind you.  Robin suggested I try with just one pair at the speakers as I currently have both ends.... I'll get around to it sometime.
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: eclein on 22 Nov 2010, 10:29 pm
Yep the extreme brightness is gone, I'm also just using one pair at the speakers  and volume levels seem about the same. I'm gonna stay with the one pair as I think with anything it could easily go too far if I add too many. Right now I'm just amazed these little things do so much and I just am enjoying the heck out of this new sound.

Yes, after reading some advise from the designer about how easy it is to overuse these grounding devices in a system (no more than 2 per system stage was recommended from the designer), I thought it wouldn't hurt to see what Mark got with only 1 GE at the speaker. I sure hope he gets his brightness issue resolved.
 
That said, I've been up in the air whether I really wanted to place another order for GE w/bananas for my Butler amps so today, I took the pair off my front/rear center speakers and installed them on the main channel - terminals of my Butler. Well for me & my system I got my answer, another level of clarity seems to have presented itself (it's only been less than 1 hour) and I can say even at this early stage of my "acclimation period", I will be placing another order once the banana version show themselves. I'm also eyeballing my Force XL sub for an RCA GE at the right channel, I only use the left channel myself.
 
Take it from someone who's a selfprofessed sick tweekfreek, best bang for buck tweek ever IMHO.  8)   YMMV full disclosure.  :D

Have you tried emailing him Randy? Ric's answered mine ok early on but I have since placed another order along with email questions and haven't got any answer. But that's ok as I can only imagine how busy this guy is right now. That probably doesn't make you any happier tho.   :?
 
So long as you have a Paypal receipt that has Ric's email address as a Verified Member, I'd be comfortable as I am while I wait for my 2nd order. You might want to go back and make sure the transaction is correct. I only mention this as I have made this address mistake before and the payment was cashed by another party. I had to get Paypal involved in order for them to send a refund. I'm real careful now with fully reviewing the transaction details before pushing that send button.  :duh:
 
As an indication of how busy this guy might possibly be, have you noticed just lately how many of them expensive Ground Control's have been turning up of sale on A'gon? That in itself to me might be an indicator of why Ric's not doing much participating in this thread to date.  :dunno:  But hopefully after the holidays, you'll be getting an early x-mas present tha you'll be as happy with as everyone else is.  :thumb:

I'm finding my system to initially be on the bright side when I 1st turn it on but after a few songs at low volume, I start touching up the volume and within  1/2 our, I'm blasting away with no fatigue factor. I wonder if it takes a few minutes for the Ground Enhancer to drain the negative energy from the drivers (acclimate themselves?) before things start sounding their best? It might not be just a bang/bang effect where optimum results just instantly appear when firing up your system is what I'm thinking.  :dunno:
 
I'm also wondering what effect these Enhancers might offer on a power conditioner? I happen to have an unused ground terminal on my BPT conditioner so I'll be looking at that.

satfrat,do you turn your system off when ever you are not listening to it?
 If this is the case then you are probably hearing the amplifiers come up thermal equilibrium
and you may also be hearing the power supply caps form up again after being turned off overnight.
I never turn my equipment off because the Jensen four-pole caps in the power supplies take about  the same amount of time to reform as they have been powered down.

Yes I do Scotty. I have tubes in my 6 channel Butler amps and Havana Dac. I see no value in leaving them on 24/7 but I do understand what you're saying with your high cap power supplies. Fwiw, I do leave my Acoustic Revive RR-77 w/KingRex power supply on 24/7.  :eyebrows:

I have used the zip cord tryout test and am somewhat beside myself on  what may be happening.

He also said, "in my speakers, the GE devices worked best as a pair, both connected in parallel to the neg. terminal of the tweeter, after the crossover.  Adding extra ones elsewhere, including midrange, bass, and subbass terminals, or on my amplifier, clouded up the sound"

I mention it b/c when I just inserted 8 GE's into my system (active biamped so on speaker high/low and high/low amps), I pretty much lost my treble, eh "clouded up," which is surprising since people spoke of brightness initially  :scratch:

Time for some breaking in (what?) and possibly start taking out some GE's one by one...

On the positive side, I gained a couple notch more midrange 3-D body and texture.

These remind me of those cardas plugs with the resistor in them, you plug unused rca's with them. Everything with a wire attached is an antennae for noise. It looks like these blanket the speaker terminals and resist noise from being amplified.

The very first night, like 6 hours in my system, I also experienced some rather harsh brightness which was gone by the next day. Its only occurred that one time and I've swapped out a bunch of different speakers since then. Its weird and as mentioned before it seems to take some time for the effects to really strengthen, like the wire starts out cold and then over time accumulates whatever it is that it accumulates and roughly 20-30 minutes in after a change the effects are evident. I have had these attached to 4 different pair of speakers over the last week or so and all were affected in a positive way.
 
When someone figures out exactly what these do please post about it, I keep reading about Ground Planes and then my mind glazes over...enjoy!!! :thumb:

It's interesting people keep saying this.  Would you guys the "brightness" is in the true treble proper, as in >10-12 kHz range or actually in the low-treble/upper-midrange area? 

I'm actually experiencing noticeably less energy (8 GE's in system) in high treble but more "pronounced" texture in midrange, which *may* be construed as brightness, grain, whatever..

Well I'm feeling that there is a clarity gain through out the frequency range so if what is said is true in the advertising of grounding devices, {that being these Grounding devices add nothing, only allow what's already there to be heard}, any brightness would seem to be an extended frequency range that's always been there and is finally being heard.
 
Unlike some, this "brightness" for me is more of an awareness that I don't consider being as actually "bright" cuz there's absolutely no fatigue that would normally result from such a condition. For me & my system, these Enhancers only result in obtaining much higher volume levels that I've never been able to comfortably listen to before.  :singing:
 
This ultimately results in my placing a second order for me system.  :green:

After placing the GEs, all frequencies were "boosted" and the sound was bad.  As seems to be the usual case (perhaps this has to do with hearing rather than anything else), breakin was from the lower frequencies upward.

After about 10 hours of breakin, the HF are out of balance and too bright.  I don't hear this as extended range, but sibilance where there shouldn't be any.  Since my speakers are biwired, there is the option of removing a GE from the HF/midrange.  Time will tell....especially in the long term.  I've used other tweaks that sound great in the short term but reveal themselves to either artificially boost or, conversely, smooth the sound.  It is difficult to find one that kills the noise without making the music less natural.  The two most natural, to my ears, are balanced power and PI Audio's Majik buss.

Post by: Jon L on 29 Nov 2010, 03:06 am
Been doing some careful experiments at home.  The "GE Effect" goes something like this in MY system.

1 GE on speaker AND amp > 2 GE's paralleled on speaker > 1 GE on speaker

Upon some pondering, the "GE Effect" to me is similar to a really good paper-in-oil capacitor.  Those who have changed out a pretty good polypropylene cap with a good PIO will have an idea. 

At first listen, there will seem to be less extreme highs.  This is probably real, but over time, one gets used to this sound, and the other benefits stand out more.

Speaking of benefits, you get a ton more tonal richness, textural vividness, and girth/weight to notes.  Bass also becomes slightly looser/freer, perhaps not as razor-defined but more woody/resonant. 

More importantly, after your ears acclimate to the new sound, music just sounds more involving, attractive, and addicting.  I felt that 2 GE's paralled on speaker sacrificed less extreme treble and more even frequency-wise; however, I ended up going back to GE on speaker and amp because I missed that specialness, warts and all.  Still the best $100 I've spent on audio in some time (8 GE's for active biamped system).  What's better, everything is reversible easily.  Thumbs up, Rick  :thumb:

P.S.  Obviously, everyone's system is different, so YMMV, etc, etc.

so...mine arrived earlier today; I ordered 2 pair for my biwired VonSchweikert VR4's with upgraded drivers. After putting them onto all 4 negative terminals, I let them run in for about an hour and a half before really sitting down to listen.
My impression was disappointment, my all solid state system was not nearly as resolving or detailed, in fact the highs sounded smooth but muddy, as did the bass. wondering...could these things work differently on all solid state systems ( seems that many of you are running at least some tubes )? Are the VS speakers built differently?
Next, I removed the ge's from the tweeter/mid modules and the clarity returned, albeit, slightly more edgy?digital? but definitely more enjoyable...after a short listen, I hooked the now spare ge's to the neg terminals on my Krell amp, on the outputs that carry the low frequency signals to the bass module of the VR4's, which still had the ge's. Voila! Nice! bass seemed to become more defined and some grunge and bloat was removed, the system seems to 'swing" with excellent pace and rhythm.
I guess time will tell...in a few days I might try reconnecting them to the upper speaker modules again and have another listen.
Anybody have any thoughts???

So far so good here, just using one pair at the speakers negative terminal. I have a powered subwoofer and hung one on the RCA plug inputting it but didn't notice any real changes, probably not the best way to hook it up to a sub anyway.

After having these in my system for a little over a week they are keepers, I love the clarity and imaging benefits they provide. I'm thinking if I get too many involved in the chain I could very easily go past "Good" sound and screw up the nice quality I'm getting now. My system is very basic so for me one pair works just right. I'm sure others with more elaborate setups would benefit from possibly adding more and aside from the first night of "brightness" in my case these have settled in very nicely.  :dance:

No amount of reading will help this and this is pretty much a staight forward tweek as far as it's application. No big secrets about which direction they should be pointing from the loudspeaker.  :lol:  If Bud, the inventor can't give you the answers you seek,,, and he's offered quite a few answers in the links I provided, then I guess it's just up to you & your ears.  :thumb:

They need time to break in. When I installed them my system sounded so bad I removed them after 5 hours. I installed them later that night and let them burn in overnight.

Hi Bacobits1,

I see you have your Ground Enhancer on the positive terminal of your speakers. Did you find that it performed better there?

Post by: bacobits1 on 30 Nov 2010, 07:35 pm

Your right.
I gotta check that out.

What happened was I was inverting phase on the amp end. That's how this happened. It is now corrected as far as the picture and both ends of speaker cable are + to + and - to minus. The enhancers are on the - terminals to the same effect.
Sorry I didn't want to cause that confusion.

I'm losing it. :scratch:

That makes sense. There are no phase-inverting components in my system, so I didn't have to consider stuff like that.

I must say I have the best sound that I've ever attained in my system since installing Ric's Ground Enhancers, and I don't even have my best CD player in the line--it needs a repair! I had a few issues with the brightness that others have reported, but it turned out to be problems in other places:


Putting Ric's GE's in my rig has been like adding the final piece that ties everything together. They're simple and straightforward to use, but they're by no means plug-and-play. If you take all of the usual and necessary steps of good audio husbandry you'll get terrific results (if I'm anything to go by...)

Bud did say in his DIY Audio thread that he can "tune" his loop based on user feedback to the basic design. That has to include one of several variables:
- length of wire
- guage of wire and or # of strands
- amount of dielectric used

If so, then someone should be able to tell us what might work best if we find the basic design to be too revealing of the high end, and or hard sounding.  A direct answer, like "add a 1/4" piece of dielectric to the bottom part of the product" is more what I think most people are looking for, rather than a scientific explaination without a practical instruction.

So, any ideas on what one might do if the product doesn' settle down with break in, as some have reported in their systems?

I've been Paypal'ing him an order with $5 shipping and an exact description of what I want (hooked/straight/RCA about covers it). I've also send him an email and even tho I got answered the 1st time, I haven't received any order confirmation with my 2nd order and I fully understand the reason why.

but they're by no means plug-and-play. If you take all of the usual and necessary steps of good audio husbandry you'll get terrific results (if I'm anything to go by...)


My hooked Enhancers were of the plug n' play variety for all intent & purposes. No installation protocol was needed or rituals followed to get to where I fell in love with them quite quickly. Guess I was just lucky hea?  :lol:

Well the best I can offer is you read the DIY thread here (http://www.audiocircle.com/index.php?topic=87809.msg869914;topicseen#new) and the Audiogon threads here (http://forum.audiogon.com/cgi-bin/fr_srch.pl?&1&procsrch&3&4&) for hidden clues as to what you're suppose to hear.

Why would you need clues as to what you're supposed to hear? Are you saying it's all just the power of suggestion operating here? :)

well, it's been 2.5 days since I received my ge's. after much experimentation I have found a combination that works in my system, and yes, they DO work. I have them on the tweeter/mid module of my speakers and the corresponding output on my amp.
first, I will recommend that they be placed on the inside of the spades (on the post). originally I had placed them between the spade and the nut, on my speakers they seem to sound much better secured to the post.
I biwire my speakers with two separate runs of acoustic zen satori from two outputs on my krell amp, interestingly enough, when I had them placed on the terminals of both the bass module and the upper module, it sounded awful, muddy, congested, boomy.
It wasn't until I removed them from the bass module that I realized the sonic improvements most of the users on this thread have realized.
I did a blind listening test with my wife, inserting and removing the ge's...and the difference with them in the system is now significant ( they did seem to need some break in time as well).
What we are hearing is a reduction in 'digitalness" , more weight in the overall sound, perhaps a bit less transparency, but overall a very pleasing, easy to listen to sound.
As long as nothing changes negatively from here, they will remain in my system!

Interesting. I will try them inside the spades.

The extra weight and richness with less "digital" sound is addictive, but if one wished for a little more transparency/air, strategic placement of (good) silver cables, power cords, and metal cones/footers can achieve that without impacting the weight too much IME..

I have been moving various power cords and ic's into and out of my system and had landed on a combo that sounded really nice...and I thought that they would stay awhile...

I am planning on upgrading my preamp from an Audio Research Ls3b (solid state) to a tubed pre, maybe something from BAT in a couple of months...

Hi Robin,

I'm not suggesting they're difficult--they made a positive difference wherever I put them--it's just that with minimal effort they can sound spectacular!

If you have been reading up on this tweak you should know that it hasn't worked in every case because it seems to be system dependant.

Sorry guys, I have been swamped with work (finishing the last 3 Oppos and a few other things too) and also my emails were not being delivered.  This includes emails from Paypal that I had received a payment.  I took my spam blocker off and called Comcast today and now I just got an email from Paypal so maybe its OK now.  I will answer all emails that I have in my system tonight....so, if you do not get a reply then you need to resend....cuz for the last week many emails have not gotten to me.

I don't think there is one post about damping the GEs.  The GEs are mounted to a vibrating thang (speaker) by a single solid core wire.  This wire is going to vibrate and so is the GE.  Please use the cotton string supplied or whatever and damp the thangs.  I think some of you will be pleased with the difference.  There are no hard fast rules here and I will have pictures soon on the website showing this done, but I can describe here some possible scenarios:
Tie the string relatively tightly to the GE near the heatshrink closest to the connector...then tie the other end of the string to the speaker wire that it is laying next to or just tightly wrap the string around both the GE and the speaker wire.  If your GE is sticking in the air not near the speaker wire then you can use some magic tape on the back of the speaker (leaves no residue when removed...also bend one end of the magic tape under so you can easily remove it) and use some Blue Tack to hold one end of the string to the tape on the speaker and tie the other end of the string to the GE with a little tension.  You can do this on the back of the amp as well.  Also you can kill some resonances in the GE by tying some sting around the GE tightly in two places (on the cotton) and then tie it with some tension to something else with another string.  You could also just use some Blue tack and scrunch it between the GE and whatever.......use your imagination. 

When I first played with this technology over a year ago I had them soldered to the output jacks inside my modified Oppo and they were just sticking out in the air right above the circuit board.  I tightly tied a piece of string around each one and with some tension glued the strings to the circuit board.....way better sound.

I have had four people comment to me that damping them made a noticeable improvement.  What do you hear by damping them?

At this point from all feedback received directly and on the web (here and other forums) it seems that about 80% of the customers receive direct immeditate improvemnt with the GEs.  Another 15% seem to need some overnight burn in for them to be beneficial and maybe 5% are getting a difference they do not like (none of these people to my knowledge have tried damping and some are dismissing it without break-in).  Not one persion has yet said they hear no difference.  My sense is that with damping, experimenting with how they are mounted and break-in that the number of people in the last group will drop.  There is nothing in audio that is absolutely universal but this comes pretty close. 

The only one returned for a refund was by someone who is using a PS Audio GCA600 Ice Power based amp that has no true ground.  He said it veiled the sound and made the images fuzzy (the total opposite of what almost everyone says).  I do have other customers with Ice based amps that love them....so not sure what is going on here.  Remember, if you do not like them then just send them back for a complete refund.

Another thing to try is putting them on the hot.....along with putting them on the ground or by themselves without any on the ground.  These things maybe work in mysterious ways so maybe they work just as good on the hot......I want to sell you more....he he.  I know of no one who has done this including myself.....Who will be the first to try it?  Who is is mister "Tweak"?

I had some wrong wire delievered so this is holding me up a bit but I should be caught up with all orders taken by this last weekend by mid next week.  I should have some time this weekend to finally start the customer comments page and put some more pics and info up.

I have tried damping mine...I've gotten the best results with having the ones attached to the speakers damped but not the ones at the amp end...go figure :scratch:

Post by: Jon L on 2 Dec 2010, 06:00 am
GE's are definitely amp-dependent IME.  While I liked GE on both speaker AND amp with my 2A3 SET, when I tried them on my EL84 single-ended pentode, two GE's were a bit too much, resulting in that "brightness" (actually, more like over-splotlighting on upper-mids), but one GE on speaker was perfect.

I am using a pair on the speaker - end only. After flipping my wires from inverting phase, they are now connected direct to the terminal and tightened down. No banana plug used this time.
The result is they are even more pronounced and also on some material dynamic "in your face" I will call it. I suspect that to calm down.
I will try to dampen them next. I did not try them on the positive terminals. I don't think I need another pair on the amp end either.
My WyWires had the same effect when I first put them in. This adds even a bit more to the presentation. The GE's have got to be one of the most obvious tweaks in years at a most reasonable cost.  :thankyou:

That's not my experience at all Ric. I have a heavily modded PS Audio GCC100 Ice Power based amp, (which is basically the same circuitry as the one you mentioned) and the effects of the GE's have been startling!

Please don't burn yourself out before I order the RCA version!

So, any ideas on what one might do if the product doesn't settle down with break in, as some have reported in their systems?

Clean your connections! Adding the GE's seem to increase the performance of the equipment they're attached to. It's a bit like adding a new amp (for example) that totally outclasses the components that surround it--it really shows up the weaknesses in the rest of your system. The transparency the GE's bring, seem to allow small changes to shine in a revealing way. If your experience is like mine, the GE's will sound good when first connected, but with attention to detail--stuff you would be doing anyway--your equipment will start to fly! I haven't been as excited about a tweak in years!

Well I've had my Ground Enhancers on for 24 solid hours now and their contributions haven't faded in the least during the system(and my) "acclimation" period. I find the benefits to quite dramatic in my system which is already heavily loaded with power, signal, and other tweek conditioning. The sound stage expansion is likened to my Acoustic Revive RR-77, only greater and more importantly comes with the inner clarity that really accounts for this depth perception of the sound stage.
 
While I hadn't actually noticed any "ringing" that's said to be caused from the long wire lead, I did find it benefitial to use the included string that I attached from the Enhancer's tip to my speaker cable to add a very slight tension to them.

I cleaned all my contacts/connections with DeoxIT and DeoxIT Gold and then attached the GE's to the negative terminal on the speaker side (Gallo Ref 3's) and the amp side (Llano Trinity). I listened to some CD's that I am very familiar with and I do hear more defined bass and as other people stated, midrange vocals seem more focused. I will continue to listen this weekend to make sure I am not imagining things :icon_lol: Since I use Anticables, it was pretty easy to anchor/dampen the GE in between the positive and negative wires as you can see in my photos.

Bud suggested (on the other DIY thread) that if you are experiencing too pronounced a high or a hardness in the sound then you may have too much dielevtric in relation to wire. He said to extend the connection point with about 2" or copper wire.

So, it's a good thing Rick did this for us already  :thumb:

I extended the length where I connect my GE's, connecting them to my binding posts at the extreme end of the wire. I also cleaned everything again. Now it might be additional break in, or more cleaning, or the extra wire length, but I believe the top end has smoothed out and become more natural sounding than before.

Worth a try for some of you experiencing this problem, at least.

Enjoy,
Bob

Far be it from me not to try anything that might improve what's already great sooooo, I took your advise and re-ProGold my connections, placed the Enhancers closest to the loudspeaker/amp terminals and even tho I had already used the provided strings for slight tension on the "antennas" at the loudspeakers, I hadn't done the same at the Butler amps,, soooo I did that also.
 
You were right, even further clarity gains were realized and more smoothness obtained. Only took a second to do, but a very well worth second to take indeed.  :thumb: 
 
Like BobM says, experiment & don't give up early on these little gems, they are worth much more than their weight in gold IMHO. Heck you got a full 30 day full money back guarentee(for november orders anyways), why not use the full time and experiement if you're having issues?
 
Oh yeah, where the heck is my 2nd order Ric???  :lol:  just kidding.

Robin,
you're right, these things can do wonders, and it is certainly worth some time and simple 'experimentation" to achieve excellentl results. Bob's advice is well heeded, as was my moving the position of them on my terminals....
since even Ric claims that he's not exactly sure how or why these things "work", any further tweaking to get optimal results seems to be a "no brainer"
my system is sounding great and I for one am happy that I didn't give up after my initial dissatisfaction....
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: HumanMedia on 4 Dec 2010, 02:31 pm
I'm also finding big differences depending on location.
Mine don't sound good on amp end.
Mine dont sound good on treble speaker posts but better on midrange and bass speaker posts.
After this thread inspired me to experiment further, I discovered that the GEs sound best not screwed onto the binding post but connected into the back of the speaker cable spade connectors. (improved high frequencies)
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: bacobits1 on 4 Dec 2010, 04:43 pm
How did you do that?
Re-connect, by soldering on new spade connectors with both the ends of the cable and GH end in the spade connector?  Some of the descriptions are confusing. Sorry.

Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: HumanMedia on 5 Dec 2010, 10:28 am
Yes, that's the idea.  Although on my speaker cables I have spades I connect by hex nuts to the crimped cable (think WBT).  I just unscrew them, put 1cm of the GE lead in the collar with the crimped cable and lock them in with the hex nuts.

For my setup, 1 GE on the speakers negative bass binding post is the best.

They really emphasise the midrange eh?
Taking them out really gives another perspective on what they are actually doing.
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: BobM on 5 Dec 2010, 12:50 pm
I wound up getting some banana connectore and screwing the GE's into them at the very tip of the copper wire. Then plugging these into my speaker binding posts, after cleaning everything (plyug, wire, post-hole) completely and tying the bottom end of them to the wire with the supplied cotton string ( 2 sets, I bi-wire). Voila!!! No high frequency hardness. No overt forwardness. Nice and smooth and spacious. I'm done and enjoying them now.

My nervosa will probably kick in at some point and I will experiment with them on the back of the amp as well, but right now I'm happy as is.
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: BobM on 6 Dec 2010, 02:11 pm
So I played with them a little bit this weekend. To begin, they are on the + speaker terminals in a bi-wired installation, because my preamp inverts. This sounds very good with no forwardness or top end emphasis since I installed banana plugs and hooked them at the very tip of the copper wire.

I did move them to the - speaker terminal, but heard that forwardness immediately.

I took them all off and heard the soundstage compress.

I put them back on the + terminals and heard the forwardness. This disappated over the course of an hour back to the pleasant sound I started with.

So this leads me to believe that any quick A-B test is pointless and the GE's need some time to "acclimate" after being moved. I will have to repeat this test on the - terminals and maybe on the amp when I can give them time to do so.

I found a delayed response with the makeshift loops as well.  I went through the in and out comparison blind testing and came up with no difference however feel sure I hear the difference when they are in for a period of time. It's frustrating when this type of stuff happens with no apparent reason. It reminds me of the cd test sweep to condition your stereo.  I have never tried that one but it is supposed to clear out the grunge while playing the sounds.  In any event just because I don't understand it doesn't mean it doesn't work. It does make me feel a little more comfortable when I can relate to what is happening.

I have had mine on a bunch of different speakers and they take time for me also to acclimate when changed. Of all the tweaks I have made since starting this hobby this easily is the coolest, cheapest, and easiest one yet with the largest payoff. I'm enjoying the fact that we don't absolutely know why they work, but work they do!!! I'm into my third week with these installed and hear no reason to take them out of my setup. Its just one of those things you gotta hear... and my rig is fairly straighforward.

Hi Daniel, I think you'd have better luck emailing Ric than posting here as he's only posted here a very small handful of times in the 4 week lifespan of this thread. In fact I just emailed him with a question on my order a little under 2 days ago and got an answer today from Ric. I think he's finally getting caught up on his back list of orders so if you've already emailed him, I'd email him again or maybe even consider calling him here.  (http://www.tweakaudio.com/EVS-2/Contact_Info.html)
 
You didn't mention how you paid for your order but if it was by personal check, that in of itself could be the cause for delay.  :dunno:

Taking into account how buried he's been with orders, I'd give him 1 more shot at answering an email. If Ric hasn't answered in 2-3 days, call the guy. Ot just call him now which is what I would do given the length of time that has gone by. The trend has been for Ric to fill orders in the order that he receives them. Could be he already filled your order and there's a shipping issue. Only Ric can answer that one and this thread probably won't accomplish that for ya.
 
If my experiences are any indication, the wait will be well worth it for ya.  :thumb:

Ric emailed me several days ago that mine were shipping last Monday, then emailed again that the wires were incorrectly sourced, so he committed this Monday.  Voila, a USPS notice was emailed Monday, and the GE's arrived yesterday.  I have their installation on my to-do list today.  :)

Thanks Robin,

I already emailed Ric twice. I will do it again tomorrow morning on my office laptop. The payment was made through Paypal a month ago. So no problem on the money side.

Regards

Daniel

Hi Daniel, any luck in contacting Ric concerning your order? I've been hoping you'd update your post here with some positive progress with your order.  :o
 
Cheers,
Robin

Got mine yesterday...ordered on the 22nd. I emailed Rick twice during my wait and he usually got back to me within 24 hours.

Haven't installed yet...hopefully this weekend.

Well I don' know how Daniel's faring on his 5 week old order but I got my email shipping confirmation on my 2nd order for 7 more hooked Enhancers and 2 RCA Enhancers. Depending on how my experimentation goes with the RCA's, I sorta suspect there will be a 3rd & final order.  :green:

Well, I was contemplating not giving any feedback until I tried the GE's in several different iterations, but then i thought...what if my initial feedback hits a note with another user and I am spared the "n" number of iterations I could have to go through!   :thumb:

First, my setup.  I have Modwright KWA-150 monoblocks that feed SP Tech Revelation custom external mundorf crossovers via ASI Liveline speaker wire.  The crossovers are jumpered and the output of each lf and hf signal path then go to a set of Aether Audio (formerly SP tech) magic boxes which are closely umbilicaled to the crossovers.  The output of these magic boxes use Aether Audio custom speaker cables to the HF and LF binding posts on the speaker.  Although one would assume that this presents about nine different GE location scenarios I have come to the conclusion that my most effective scenarios are all negative-terminal -speaker binding-post-based, and are one of the these five:
* single or dual GE's on HF
* single or dual GE's on LF
* one on each
I've discounted putting them on the amp end cuz it is full range and likely the GE placement there would be more difficult to isolate, but I'll try after each of the above...if someone has strong feelings one way or another..

So...I installed them last night and they are in a typical setup, scenario 5 (one on each hf, lf).  How do they sound??  Well...the good: incredible micro detail and ability to hear into the recording, as if the noise floor dropped 3db or more!!  Incredible.  I am floored at the instant "never heard that before" results.  The bad:  imaging, especially center fill stuff like female vocals, has become almost as wide as the soundstage...as if that aspect has had it's polarity inverted (and yes, i tried invert polarity on my remote, to no avail).  I will listen again tonight after some long break-in, but my next step will be to follow Big B's idea and take them off the woofer posts and double them up on the tweeter ones.  I'll report back before I do too much else.

Any opinions?

Ted, before I placed a 2nd order, I took the set of Enhancers off my 2 centers (I initially got a set for all 6 loudspeakers only) and placed them on the amp end of my mains. They have never left and my 2nd order will effectively cover both ends of all my speaker cables. Definitely try them on both ends of your mains.  :thumb:

Tvad,
On Audiogon two weeks ago you concluded:
"In my system, to both my wife's ears and mine, the EVS Ground Enhancers emphasized treble to a degree we found unpleasant over time. We believe the tonal balance without the EVS Ground Enhancers is more natural."

What happened since then?

On the same A-gon thread a user talks about "diffuse imaging" and "loss of image precision" with his GE's (as opposed to his more expensive AP GC's, btw).  I would use the same terms, although no one else on any of these forums has described that phenomenon (unless that is what Brian Cheney referred to as "cloudy" during one of his less successful setups). 

Robin,
i'll try them on the amps then, but will need to pull them off one of my speaker drivers, HF or LF.
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: rhyno on 12 Dec 2010, 08:35 pm
evidently great ears hear alike (props to you BCheney).

tried the EVS GCs in the following locations on my speaker /amp setup
Watt, Puppy & Amp
Puppy & Amp
Puppy
and Puppy *2
(always on negative)

simply put, best sound was achieved w/ 2 pair in parallel on Puppy. more liquid, relaxed top end, very musical. what a great tweak.

i also tried on ground of CDP (EMM CDSA) and Preamp (Audio Horizons 2.1). in both instances it was better WITHOUT the GCs. (in a buddys rig, his DAC sounded better w/ the GCs on the ground post, but his AC ground was disabled on the DAC). YMMV

Your SP Tech connections are way over my head Ted so I can't help ya there. But from what Brian Cheney and you have stated, it makes me glad I'm only working with a single set of speaker terminals.  :lol:  Guess you'll just have to experiment Ted and see what works and what doesn't. Have fun, you still have 26 days left to audition them.  :thumb:

My one pair are still installed on each negative terminal at each speaker, I don't have a biwired/biamped setup and my system continues to benefit as it did when first installed. I have not run into any issue with clouding or diffuse imaging, if anything the imaging got better for me. The soundstage is wider for sure, there is more clarity and the speakers have become extremely transparent. When I say transparent I mean to try and communicate that the sound seems to be coming from the entire area of the room where I have my speakers, it doesn't sound like its coming directly from the speakers....follow me, its like the speakers have vanished and the sound just emminates from the entire wall where my setup is.
 I'm truly enjoying the improvements these gadgets have brought on, I can sit back, close my eyes and hear the music all around me and in some cases-I forget which CD I was listening to- the imaging makes it sound as if the music is coming from behind me, its pretty neat.
 So for me less is more, one pair is all I need....have you guys seen some of the prices on this same type item now that a few folks are carrying them online? I have seen them with nice terminated ends for 4 times as much as my pair cost, I'm just glad I jumped in early. If Ric ever comes up for air I for one will thank him as I have no desire to take the DIY route and like they say "timing is everything".

Well, after several iterations in setup (both on hf, both on lf, one on each and one on amp, one on each and one on crossover output) I settled on putting a pair, in parallel, on each LF binding post (negative).  This seems to have the most clarity while presenting the least negative effect, which is still comprised of a slight bloom or smear/instability in center image, esp vocals.  It was undoable on the HF side.  I've got them breaking in over night using some test and break-in frequency sweeps, etc.  We'll see what happens tmrw.  So far I sense a slight overall trickiness or phase anomalies to the sound that seems unnatural but presents itself as "wow" initially.  Hopefully, the downsides will dissipate over time.

Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: AB on 13 Dec 2010, 04:22 pm
I received my order on Saturday and played with them yesterday.

About 3 weeks ago I built and installed a set of four DIY CAT5e versions on my biwired speaker posts and have been super pleased with their effect. Except for a hyper detailed "busy-ness" on complex music they clean everything up and sound very natural. The DIY versions were improved when I added some cotton sleeves to the wires - less of the "busy-ness." And they do seem to break in.

On to the GEs... I am comparing them to my CAT 5e efforts only. They've been in my system for three weeks and have become the new normal for me.
This probably makes my review a bit less relevant to most but seeing as these are SO system dependent, any review must be read in the context of the individual system the GEs are used. Right? Anyways...

I initially tried the GEs on the HF speaker binding posts only. There was a subtle change - less detail, less focus than with my home brews.

Next, I tried them on both HF and LF posts. More of the same - less detail, less focus and the SS shrunk quite a bit. They sounded pretty grainy and unnatural too.

Each of these configs was left in for a few hours for some amount of settling to take place. Any change over the few hours was minimal.

Next, I tried one pair of GEs on the amp only. The result here was similar to my home grown CAT 5e wires on the speakers. But still there was some loss of image focus and SS width compared to the CAT wires.

Next was GEs on the amp and my CAT wires on the HF and LF speaker posts. This was the best of all - so far. The sound was very clean and natural with an extremely wide and detailed SS but with a touch of mid range weight. No negatives but the improvement is pretty subtle overall.

I also tried GEs only on the LF speaker posts only. Here they cranked up the bass and bass detail a lot. VERY impressive but too much for my system - I have enough bass, thank you .

I have 8 of these things - 6 wired and two RCA versions. The RCAs have had no real noticeable effect so far. But who knows... lots of combos to try yet.

The GEs certainly have an effect in my system. The CAT 5e wires do too. I will continue to play around with all of these and report back.

All in all this thread and these gizmos have been a lot of fun.  :thumb:
Title: Re: Introducing the mind blowing EVS Ground Enhancers!
Post by: satfrat on 13 Dec 2010, 11:32 pm
Today I received my 2nd order that consists of 7 hooked Enhancers and 2 RCA Enhancers. I placed 1 hooked Enahncer of the ground terminal of my BPT and the rest on my Butler amp negative terminals so I now have Enhancers on both ends of all my speaker cables. I have 1 RCA Enhancer on the composite video of my DirecTv DVR and will be swiching that one over to a composite input of my Sony XBR TV at halftime of the Houston/Baltimore game. I'm not really seeing any noticable improvement on the DRV but I've tweaked out my video so much that this doesn't surprise me. I'll have to do a ton of A/B'ing to really make up my mind on this install option. I have the other RCA Enhancer on the right channel of my Force XL subwoofer's LineLevel inputs with my Bybee/Z-Sleeve laced subwoofer IC gracing the left channel. I feel like there's a tightening of the bass, somewhat more articulate. Volume level checks found no change on any of the 6.1 channels.
 
I have now returned to my multichannel music listening preference, Dolby Pro Logic 2x but with the center channel shut off. While I had preferred stereo when I had the Enhancers on both ends of my mains only, now that the rears are Enhancer'd up likewise, the clarity balance of all the speakers has returned as has my preference for the fuller "house sound" that multichannel has always given me. But for the past 4 week, I can definitely see the stereo purists point of view.  :thumb:

I'm not really seeing any noticable improvement on the DRV but I've tweaked out my video so much that this doesn't surprise me.

OK, I couldn't wait til halftime so at the begining of the 2nd quarter, I plugged the RCA Enhancer off the DirecTv DVR and placed it on a composite input from the back of my Sony XBR CRT Tv. Well it took all of a second to see the HD improvement which I also wasn't expecting considering all the tweaking I've done to that set like installing an IEC terminal for a power cord with dual Bybees, heck I even have Bolder Cable Bybee RCA adapters on all 3 component video inputs. Yet this little RCA antenna had a positive effect on the picture which I can define as simply a more refined color base with enhanced sharpness. Nothing really major mind you but after not seeing much of any gain from the DVR, I wasn't expecting anything from the CRT either. It's a pleasent surprise that the little bugger has found a home.  :eyebrows:
 
On another failed experiment, I also tried the RA Enhancer on an analog audio input on my Sunfire Theater Grand 4 processor, which btw already sports an Acoustic Revive RGC-24 Grounding Conditioner. Well the sound simply went flat, like the life had been sucked out of the processor. But the second I pulled it off, the livelyness instantly returned. I might try replacing the RGC-24 with the RCA Enhancer and see if I might be able to place the highly expensive Acoustic Revive on the chopping block. But it does do such a fine job on that processor, I'd hate to part with it.
 
The RCA Enhancer on the Force XL kicks major butt. My bass has never sounded so textured as it now sounds. I really like this application. As for the BPT grounding terminal application of a hooked Enhancer, I really have no clue is it's contribution to the overall effectiveness of my system in general (everything in my system goes thru the BPT) but for $12.50, I'm sure as hell not sending it back. It's there to stay, fwiw.  :lol:

Post by: RPM123 on 14 Dec 2010, 06:03 am
I've had mine for about 30 days and they are definitely keepers! Started out with one on each bass negative speaker terminal (I am using jumpers)  and heard an immediate change in sound, but not necessarily better. Highs seemed a bit "brittle", with the overall the sound being slightly etched. Bass went up a notch too. I left it that way for several days and things started to improve. After that I hooked a pair up to the amp end and that's when I started to hear their potential. Another week went by and the sound started to really come round. Fast forward to the present and all I can say is that I have never heard so much improvement from so little investment!

What really strikes me is the better "clarity" of vocals... lyrics are much easier to discern. Vocals also have more texture and body. Highs and lows are more extended and lower listening levels are more enjoyable, although listening at higher levels, I notice little if any fatigue or irritation.  Bass and mid-bass are much tighter, such that up until I tried the GEs, I was seriously considering getting some GIK bass traps to tame a bit of bass looseness or boominess on some recordings. Now, I no longer feel a need to try them! I also noticed a difference in rhythm or timing, in that music seems to be "slower", but more "deliberate". The only other device that has that effect on my system is the Alan Maher "Quantum Studio", which I still use.

I also noticed a bigger soundstage and more precise instrument placement. I thought that my phono could not get much quieter, but that improved as well. Music is more involving now, so I have left everything as is and I don't have the desire to move them around to find out what happens. Eventually, I may try one or two on the RCAs of my integrated amp, however, I am not in a big hurry. One thing that I noticed is that if I don't play my system every day, there may be some regression in sonics, which goes away after continued playing. I'm not entirely certain of this though.

The GEs are absolutely the biggest bang for the buck that I have ever experienced!  :D

Ric is very good at honoring his money back offer. I ordered 3 sets of GEs and they definitely made a difference in my systems. Unfotunately, it was a bad difference. Even after break-in my systems sounded so bright that I couldn't stand it. So I sent them back to Ric and he refunded my money immediately. This is great service.

Post by: BobM on 14 Dec 2010, 03:58 pm
As fine as my system now sounds with the EVS enhancers on the speaker terminals, I am not completely satisfied with the somewhat diffuse imaging between the speakers. Yes, things are way wide and deep and quiet, but the center image between the speakers themselves is really not as focused as before.

So I did a little reading at Audiogon and elsewhere and found others have been saying the same thing. Here's what I tried last night and the results I got (I bi-wire and my preamp inverts).

(1) I took off the tweeter GE and left the bass/mid GE in place on the speaker - this was better mage wise, but didn't quite sound continuous top to bottom. Something is off.

(2) I put the removed GE on the amp side, leaving the bass/mid GE on the speaker - same result, not continuous top to bottom.

(3) I removed the speaker side GE on the bass/mid and left the amp side on - this is better. There is a focused center image again. The width and depth may not be quite what they were before but that hint of some kind of phase anomaly is gone.

(4) I put the other GE on the + terminal of the amp, not there is one on both the + and - amp side (my amp is balanced, so YMMV) - it didn't seem to hurt anything from #3, but I can't be certain it helped anything either.

After doing this test the top end was bright and forward, as I experienced whenever moving these things around, but it did tame back down after an hour or so of playing music through them.

Bottom line: I think I'm goign to leave them on the amp side. I think this is better for me than the speaker terminal connections that seem to cause a loss of center fill focus while expanding the soundstage.

Enjoy,
Bob

Post by: Gopher on 16 Dec 2010, 01:04 am
I received a pair in the mail today and the results are interesting...

I can say with certainty that they have changed my sound--there is a lot more clarity and transparency now--my 845 SETs sound as transparant as my Atma-sphere.

That said, its almost too much.  I'm listening to LCD Soundsystem right now and its like sensory overload with this level of inner detail.  A bit distracting.

I've noticed others have said they 'calm down' after an hour or so of play, so I'll keep listening.  First impressions are an immediate change on the negative terminals of my Zu speakers though.

--

Alright, I gave it about 2 hours... I'm impatient.  It was way too hifi sounding for me on the speakers.  I just threw them on the back of the amp terminals and things relaxed a bit.  Stil a more detailed presentation, but not to the same overload level.  I'll revisit on my speakers in the days to come--maybe leave it playing on them overnight. 

I have a second pair arriving tomorrow anyway.  I guess we'll see.  Neat tweak.

Hey guys -

Been following this thread since the start and have a question.

I just got my EVS GE yesterday. I have added them to my front three channels
in my HT setup. No downside for me, larger soundstage, tighter bass and better
dimensionality - all right out of the box.

My surround speakers are flush wall mounted. To add a GE to the negative post
I would have to bend the GE itself to accomodate the installation.

Has anyone done this? Does bending the body of the GE cause any negative effects?

I think you'd have to explain what you refer to as bending? Ric has already recommended that you use a piece of string tied to the end of the antenna so to bend the antenna to prevent it from ringing. So if when you say "bending" you actually mean that the antenna is being pressed against the wall, then I see no difference between that and the tension from a piece of string. My front center channel speaker's antenna is actually pressed aganst the video rack so I didn't bother string tying that one back like I have all the others at both my speaker and amp ends.
 
For anyone who didn't get string with their order, neither did I on my 2nd order of 7 more hooked Enhancers. No biggie for myself as I have tons of lose string lying around but I did mention it to Ric who seemed surprised that he had infact forgotten to add the string to anyone's order. So at least now he knows to look closer..  8)
 
Gopher, a little late to the parade but if anyone backs out, I too shall take them off your hands for a copy of the Isotek System Enhancer & Rejuvenation Disc. I run the Rejuvenation track each day myself and I do believe it to do as advertised.  :thumb:

I would think anything that prevents them from ringing as being a good thing. If you like what you're hearing (and I happen to do), then it's all good. I happen to love them antennas on my amp/speaker rears when listening to surround music as the presenation is much more balanced than just having them on the mains. But for usual movies/tv DD surround, I personally hear don't hear the improvement that comes with music. But then it's music that I'm primarily concerned about anyways. HT is selfsuffficient and takes care of itself for the most part when it comes to these type of music enhancing tweaks.  :thumb:

Gopher, a little late to the parade but if anyone backs out, I too shall take them off your hands for a copy of the Isotek System Enhancer & Rejuvenation Disc. I run the Rejuvenation track each day myself and I do believe it to do as advertised.  :thumb:

Would have loved to do it locally but I committed to a west coaster. 

I can't imagine why it would matter, but is there any reason NOT to just rip the flacs and run 'em from Squeezebox.  Lossless is lossless, I imagine and I'm not really setup for CD in my system.  I guess I could run it on my PS3 and send an optical out to my DAC, but thats a PITA.

I ripped my entire CD library to avoid physical media.

If that is a fine solution, I'll probably do as you do and run the rejuv. track daily--whether it makes a difference or not, I may as well as my tubes warm up.   :)

The Isotek I run daily is on HD and I found no differences myself between the HD and my actual Isotek CD,,, other than convenience. I was just thowing my hat in the ring anyways, fwiw.  :thumb:

Well, after living with only a single pair of GE's on the woofer negative speaker terminals (seems to be best overall compromise) for about a week I took them off last night and let the system settle back in for 24 hrs without them (noticed when you immediately remove them that there is some perceived harshness, but then again the amps are power cycling).  Tonight's listening session was one of the best, and I'm deciding on living without them.  In my system, with my room, and my ears, they just bring too many artificial artifacts to overcome the few plusses.  It was a fun experiment.  YMMV.

Here's my experience with them.

Have one on each speaker negative post and one on each negative post on the amp. Well, these things are pretty damn special.

I first tried them just on the speakers, and I noticed greater air and separation right away. Vocals were crystal clear, but possibly too crisp and a little thin. I then ran through some tracks and then put one on each negative post on the amp. Wow, this hit the spot. It seemed to give more ass to my low-end, like really clean bass. The slight brightness seemed to be gone and everything was in more balance now. Still have the awesome separation and air in the instruments. Midrange, mid-bass and low-bass are very solid. Sounds like my SoundScapes can go even deeper now.  :o

Have had the system running over night and when I sat down today for a listening session, it was one of the best I've had. They're keepers.

Seems like the magic really started when putting them on the amps, so I recommend trying the amp and the speakers. I didn't really need to damp them since they were usually up against something anyway, but I did tie one down and never had an issue with ringing. I previously moved my speakers away from the front and side walls, and lost some of my bass impact, but it seems like I got the bass back and more, without even moving the speakers.

I have a few extra so I am going to put them on my surrounds. Great tweak!  :thumb:

Nope, not running them biamped. I have the enhancers on the un-used terminals on the speakers.

I like what I hear better without them now. It seems like too much of a good thing maybe? There seemed be better instrument separation without them in. My WyWires take care of all else in that area.

I will sell them for $30, 1 pair with loop end.

I have not read any of the more recent posts on this subject so as to not be biased one way or the other. I received a pair of these before Christmas and attached them to the negative terminals of my speakers, Roman Audio Centurions. I wasn't able to do a lot of critical listening before I left town for two weeks, but I became aware that they seemed to act like a power conditioner, enabling me to enjoy listening,as little as I did, and mostly as background music, in the evening hours when normally my system takes a dive in sound quality because of very dirty electricity here in the hours beginning after around 5:30 P.M. There's never been an adequate explanation for this, but it happens and always has. If during the day it is 10 quality in sound, in the evening it becomes about a 5 and some music, vocal (esp. choral), strings, can become unlistenable. I have tried too many power conditioners to count, including two different PS audio PPPs, a Canadian brand of power regenerator, and many others. None did much good at all. (I even tried battery powered and passive electronic components to no avail.) Now however, after several days of listening, I find that these little things do what those multi thousand dollar units never did. They clean up the sound for me in those evening hours so I can listen with pleasure to any type of music.  Can't explain why, but it's what they do for me.

Been experimenting for the past month or so with 2 pairs of straight GEs and 1 pair of RCAs.
I've ended up with only a straight pair on the negative binding posts of my amp, and an RCA on my sub. This made the sound more liquid, increased the sense of ease, seemed to lower the noise floor (my preamp prior to GEs had a bit of hash), and increased the 3D aspects of the sound. Very, very nice!
Putting more GEs in the path rolled off the highs, made the sound very forward, and sometimes gave a "phasey" quality to the sound (esp. when the RCA was installed on my pre - no bueno). Putting a set of GEs only on the speaker's negative posts also rolled off highs and made the sound more forward.
May end up using the last set on my HT system, if I ever turn off the music!

Post by: highfilter on 7 Jan 2011, 10:01 am
Update for me as well...

I previously had the enhancers on the neg posts of my speakers and amp and thought it was great over a few days. I decided to try and remove them from my speakers to see the difference, and wow, instantly opened my eyes. Much, much more organic and smooth presentation with them off the speaker terminals. Everything improved almost 50%, especially the highs. I'll be leaving them off my speaker posts unless I change configurations.

Meanwhile I still had them on the back of my amp. I then took them off the amp and still had the sweet, organic presentation from before. I didn't really notice much of a change, but I was only comparing on a few tracks. I need to try them on the back of my amp, as it might improve low level detail and bass definition. Like watercourse, I have a DAC Cherry amp (but the Jr, not the PLUS) - so I might find they work quite well on the amp neg posts. Will try in the next few days.

I really notice the rolled off highs as watercourse mentioned, it's even more of a metallic grain from my hearing, compared to having them off. I recently just put in all WyWires in my system for cabling, and they are very organic and neutral with great detail, so the high harshness was more noticeable than before when I had my previous cables.

I'll have to try ordering some RCA Enhancers to try on my sub and maybe on my pre-amp. BTW, the bass and midrange improvements I mentioned before are still here without the Enhancers since, and are actually even better since swapping over to the WyWires cables. I might have too many things breaking-in right now to be trying this tweak anyhow, as I just got my new cables a few days ago. So I'll re-evaluate next week and give these a fresh try.

Thats a great description of how Alex's cables sound, in my setup with Wywires front to back the cables got me 85% there and the EVS ground enhancers took me the rest of the way. I'm still using one set but they now reside on the negative speaker terminals at the amp-that change made things even better sounding. I have noticed. and it may just be coincidence, but the older the speakers are that I use them with the greater the effect the enhancers have on that setup.

Post by: watercourse on 7 Jan 2011, 02:40 pm
Highfilter: GE on the subwoofer seemed like it wouldn't make any difference whatsoever, as it seemed the REL was already well-integrated with the mains. I tried it on a lark only, since the RCA versions didn't work with anything else I put them on, but dang if it didn't increase the coherence top to bottom, improve timing between the sub and mains, and increase the soundstage depth ... it really pulls the sound together like Lebowski's rug did for his room. Or El Duderino's rug, if you prefer.
RE: the metallic grain - I heard it too, but shifting where I connected the tail on the binding posts affected how much grain I observed. This is true for both the speaker and amp ends. I ended up connecting about midway on the tail for best results, and a tad closer to the heatshrink than the other end.
Also, the RCAs were not helpful on unused analog outs from my CD player and phono pre - it was phasey city.

Post by: highfilter on 7 Jan 2011, 05:37 pm
Cool, thanks for the information eclein and watercourse. These things are sure interesting and versatile - I should be able to tweak them some more.

Another question, have any of you guys tried putting the RCA or XLR versions on a receiver for HT? I have a Marantz receiver that I use for movies with HT Bypass and was wondering if you noticed any improvements in the HT area. I don't have the RCA versions but I think I'll order a few to try. I noticed the pre-outs on the Marantz receiver are not dead quiet or as noise free as my W4S STP-SE preamp, so having some on the receiver might help tame the Marantz.

highfilter - when my next pair come thats my plan is to play with them on my home theater rig, A) I'm gonna hang one on the RCA input of my sub for starters B) depending on how that goes I'll try them out on my receiver somewhere. The other day when I got my new/old speakers I had to take them off of the old ones and then forgot to put them on the new/old ones and was too lazy to pull the speakers out and do it when I remembered a few hours later so I just hung them on the negative speaker terminals on the back of my little Virtue TWO.2 amp and instantly noticed an improvement in sound, largest improvement yet for me.
 On subs are you guys just hanging them on to where the RCA connects to the sub, my sub is powered and has two RCA inputs but my amp only uses the one-so do I hang one there and then put the other into the open RCA????

Ed, I'm using an RCA Enhancer on the right channel of my Line Level Inputs of my ACI Force XL sub, my RCA subwoofer cable uses the left channel. An RCA Enhancer is also working awesome on the composite video input of my Sony XBR CRT.
 
If my hooked Enhancers were making my soundstage sound both forward and rolling off the highs, I'd have them on the chopping block ASAP. Fortunately for me anyways, just the opposite has happened for me while using the Enhancers on both ends of my speaker cables. The highs have actually been greatly improved as has the whole frequency range, like a veil has been lifted and the sound stage simply expanded because of this. Everything collapses when I remove them so,,, I don't do that anymore.  :D

Robin -

A RCA GE on an unused line level input of my sub worked very well. As did on the component input of my TV. Have to thank you for posting your test results a few pages back. My subs sounds amazing with the little GE in place. Also the effects on my LED DLP TV were amazing. Immediate difference when putting the RCA GE on a component input. The RCA GE pictures on RIC's websit are actuall my sub and TV. Had to send them pics because they worked so well and I think they should be considered step 1 in implementing RCA GE's.

I am now experiementing with damping the GE's. I am adding a piece of fo.Q damping tape on the heatshrink of the GE nearest the connector to the GE on my centre channel. Christoph Waltz opening dialog scene of Inglourious Basterds was much more organic and vocals and dialogue had more weight (bass?) and dimensionality with fo.q on a GE. I have only added fo.Q to the GE on my centre channel and compared before and after with dialog heavy media. Will do another A/B test over the weekend and post pics and feedback. I believe damping a GE increases it's efficiency (At least in my initial test it did - YMMV). 

Tweaking a tweak.... :)

For all the guys that are putting the RCAs in their TV sets, do you know if you are able to put them in while it is running and notice the effects real-time? I think that could be cool to have a friend put them in and get to see the changes flip-over - or maybe it doesn't work like that. Or maybe you could shock your friend.  :lol:

Picked up two hooked pairs. 1st installed solely on speaker neg posts (applied tension to bottom by using a type of bluetack). Results: wife and I heard nice improvement in soundstage depth and width, perception of increased detail / air around voices and instruments.

After some listening time, subsequently put second pair on neg posts of my mono amps. Seemed to be even wider soundstage and more air around voices and instrument, but lost much detail. Ended up pulling them off the amp posts.

Wouldn't mind trying the RCA version - anyone want to swap a pair of RCA for a pair of hooked? FYI - don't know why these work / don't care. They just work.

---------------------------
EDIT: Placed one each of the second pair on my preamp and cdp grounding posts respectively, and it sounds like they are going to stay there. Guess I'll have to purchase a pair or two of the GE RCAs.

These little buggers work with my stuff, the combination of items, the older JBL's, every place I've put them I've noticed a clearly better sound after installing them.

I have been listening to the EVS Ground Enhancers for a couple of weeks and am amazed at what they can do. Ordering was easy, first I sent Ric 35 PayPal dollars, received a reply the same day and my enhancers were shipped the next day.

My system includes the Von Schweikert VR2 speakers and all Van Alstine Insight+ electronics, this combination responded very well with the enhancers installed. I didn't notice any break in period, the sound and presentation changed immediatly and I have not noticed any change since. The enhancers made quite a few changes to the character of the sound.

The most noticeable change is greater separation. Instruments and voices are more delineated in space. Music that seemed to be clumped between the speakers is now spread out: left, right, and center with individual musicians easier to pick out. With a wider sound stage there is also more depth, the area between the speakers opens up quite nicely. The Miles_Gurtu album has a lot going on, the enhancers turn the album into an aural 3 ring circus.

Some people have mentioned more bass or treble, I did not notice an increase at either end. Listening to music from an adjoining room the stereo sounds exactly the same as before. What I have noticed is a faster attack and greater clarity in the treble which gives the impression of an increase in high frequencies. The VR2's tend toward a warm presentation, the enhancers bring the sound closer to a neutral presentation. I first noticed this effect while listening to Tom Petty's latest album Mojo. Tom's voice is not as sonorous with the enhancers in place. The flip side is that vocals are now more intelligible with enhancers. My stereo is also part of a 4.1 surround system used for movies and television. Voices from the phantom center channel are now better defined and easier to understand; movie sound effects have more punch too.

The EVS Ground Enhancers are quite an amazing tweak, it is like getting an electronics upgrade for almost free. The + upgrade for my AVA pre-amp cost more and didn't do as much for the sound as these little white pig tails.

Highly Recommended  :thumb:

Jeez, what a way to be remembered!  Back when Joel was starting out (Pian Man and Streetlife Serenade days) he played the Allentown area frequently.  For Ed's reference, he played at Ag Hall and also at the Roxy Theater in Northampton.  The song Allentown is based upon his skewed memories of the area.  Allentown never had a steel industry, that industry was 10 miles to the east in Bethlehem (you might have heard of Bethlehem Steel).
Allentown was a clothing mill town, home of Mack Trucks, and had a Western Electric plant  (1st transistor production line was here).  Oh, Allentown also hid the Liberty Bell during the Revolutionary War. When the song came out, the then mayor presented Joel with the key to the city.

When I was younger and still playing we used to play The Main Point in Bryn Mawr a lot and one night while backstage (which was actually in the basement) I happened upon some old boxes with cancelled checks back in the day when banks would send you the checks that cleared.
I'm looking at all these checks and immediately start noticing the names.....Jackson Browne-$35, Martin Mull-$60, Bonnie Raitt and on and on, all with signatures of the artist as endorsements so they could cash the check....way down in the pile I see -Billy Joel-$35, Biily Joel-$150, Billy Joel-$2000(as he was rising so were the paychecks he was cashing)...I grabbed a whole pile including the Joel's and used them to barter with people for equipment, food, drugs on my way up then down.......I grew up outside of Philadelphia in Media,PA....and that seems like 100's of years ago now... :dance:

Have all three pairs installed. A pair on the amps and speaker - binding posts. First impression was enhanced bass performance with something going on in the treble region. Let the system settle for an hour and the bass stays better defined and more tactle. As for the highs there seems to be no differance with them on or off the speakers upper range neg post. Sound stage was not affected. I will have to try with the amp GE's removed to see if the bass remains as stated as well as what happens to the treble and stage. Will play more tomorrow. :D

I got my pair about two weeks ago and am unsure if it improves anything. But I may not be using them in the best way. At the moent I'm just putting one on the negative speaker post (the bottom one because they can be biwired) of one speaker. Where should I install the second one?

Post by: teknikly insane on 10 Mar 2011, 05:21 am
Hi all, my first AC post here. I'm teknikly insane, but you can call me TI. I'm really just gonna pile on here and say I tried a pair on my passive crossovers (Magnat MSP-120's) and after a few hours was wowed by the results. Everything was a bit cleaner and with a bit more detail, but my moderately well tweaked system already sounded good in those areas. The best thing for me though was the much improved dynamic vividness throughout the mids. The crescendo in a CD of Rhapsody in Blue peaks with a new level of aggressiveness and Al Di Meola's intentionally flared guitar notes on Elegant Gypsy really grab me with a whole new level of cool factor - yet there's no hint of overexaggeration or any downside at all. I didn't have the OMG realization that some have had, but shure didn't feel like I got ripped off either! :D More of 'em are in my near future. These I've had in my system since January.

Also, I've had the pleasure to chat a number of times with Ric by phone and I concur with everybody else here that he's the real thing AND a nice guy and I don't think I've ever found a seller who's more in your corner and with less bias anywhere on the planet. I like to think that rather says a lot.

I still have mine in play. I'm using Zu Omen Definitions, but have no idea if the GEs work "best" with them. I also have a GE each on the ground posts of my preamp and CDP respectively.

I still use mine, neg. speaker binding posts on the tube integrated amp I'm currently using. I was using another pair in a set of Grado headphones I was modifying but have since taken them off-a bit too bright for me. I use relatively old JBL speakers if that helps at all.

Every system is different as are each individual's listening preference. There is no "1 answer fits all" solution for the use of the Enhancers ( and that holds true for wire, gear combinations, etc). Sampling & doing demo's is the only real way to get the answers you seek.
 
I'm still using Enhancers on the negative terminals of my Odyssey Lorelei's & Usher X-616's, my Butler 3150 amps, my ACI Force XL sub and my BPT BP2.5 balanced power conditioner. And I expect I always will.  :thumb:

I removed mine a few weeks back, it wasn't because they made my system sound bad it just seemed to me to be a bit too bright overall and some of the dynamics in my system were lacking. I'll try them again in a few months and see what they do then...money well spent for me buying my two pair, its a way to change the sound of my system and easily change it back. I have no regrets about buying them or using them, I still have both pair and plan on continued use.

I have not used the Enhancers, but have reported on a variation of this tweak i called the 'Pigtail' tweak. Both here on Audio Circle and over on Audio Asylum in the Tweaks/DYI asylum.
Similar enough, it is just the wire on the negative terminal, with a ferrite core added to the end of the wire.
Seemed to me the idea was going from an old original idea of just a bit of wire, to a more complex wire, so I just added a lot of metal mass at the end.
The results very similar to the results described with the EVS.
Clarity increase, better dynamics, better mids, and lows.

I added even more mass to the ferrits, so now I have bundles of ferrite (three ferrite bundles at the neg speaker end of just the bass wires.. biwired Magnepan 3.6s) and seven at the amp negative terminal (Bryston 4B-SST2), with bunches of extra wire sticking up out of the ferrite bundles.
(I used stuff on hand: ferrites 1" tall and 1/2 diameter, tubes)
Same increase in clarity, also a nice return of midrange fullness I had lost from using several powerline conditioners.
I made one with three ferrite and a bunch of wire for the Rudistor RPX-33mkII headamp, and connect it at the jack with a ring on the outside of the jack ground. (to Sennheiser HD800 phones)
I have used them like this for several months and am quite happy with the results.
Like icing on the cake.
Many others have tried my sort of tweak, and not many good reports. i have to say my tweak version is very system dependent.
I tried the 'nine volt battery' tweak version on the grounds of RCA at the preamp, and did not like that at all.
I did mention in some of those posts i think the EVA is a great way to try this sort of tweak, and thank them for making it so affordable!

Post by: rollo on 12 Jun 2011, 01:32 pm
  For my system the EVS installed at the negative speaker terminal brightened the sound.
  With so many positive reviews and Elizabeths experiments I had to try options. Having excellent results from Mapleshade products my Buddy who is a Mapleshade dealer informed me Ron Bauman was tinkering with the concept.
  Intriuged as per his suggestion I ran 2 8 ft. ribbon wires connected to both positive and negative terminals of the amp. Gave a listen and was taken back as to the result. More info and no added brightness. Bass was clearly defined and better focused.
  The set up is ugly as sin. The results positive for me. During the experimintation phase a 10ga stranded wire with a bananna attached to the end [ mass a la Elizabeth ] proved positive as well, frankly a beter result than the EVS, go figure.
  It was a fun experience to try with varied results. There is something to this tweak and maybe an overall winner for all will appear. In the mean time if you desire give the Mapleshade idea a whirl ya never know until you try.

Post by: TJHUB on 16 Jun 2011, 07:51 pm
Kind of late to party here, but I received 3 pairs of GE's a few weeks ago.  I've been playing with them in different locations with VERY different results.  I could write pages of comments, but I don't have the energy or desire to do so.  So here is a short version:

When I attached 1 pair to the negative speaker terminals on my speakers, the sound changed immediately.  It was not for the better.  I lost some upper frequency tones verified with certain tracks I use for critical listening.  It didn't take more than a day for me to figure out that I couldn't live with the sound I was getting.

I tried a pair of GE's on the amp's negative terminals with the same effect.  I even tried a pair on my preamp and that really took away the detail and resolution of the sound.  Not good.

So before I gave up on the GE's altogether, I decided to try them on my speaker's positive posts, the sound was completely different.  I lost no detail or resolution and I'm convinced I've gain a level of clarity, decreased background noise, slightly more defined bass, and increase separation and sense of space.

Ok, this is good, but why the POSITIVE speaker posts?  This sent me on a quest to find out if one of my components was inverting absolute phase.  I couldn't find any information on my gear that stated the phase was inverted.  Then I set out to figure it out on my own.

I can't seem to definitively figure out if my absolute phase is inverted or not.  I tried the battery test and couldn't really determine if the driver was moving in or out as it bounces quickly and I just couldn't tell for sure.  Then I did some tests with my finger on the driver and convinced myself that the phase was inverted.  So I flipped the speaker terminals at my amps and I convinced myself that the drivers were now in the proper phase.  This I'm 15% certain of... :roll:

So now I'm listening to my speakers with the absolute phase inverted from where I've been listening for the last year or so.  My thoughts?  I'm NOT SURE!  This kind of stuff drives me INSANE!! 

I listened for an hour without any GE's installed and got used to the sound that sounded really familiar to me.  It is possible that the bass sounded a bit punchier, but I won't state that as fact.  It's more of a gut feeling than anything.  I didn't really notice anything else different about the sound, so inverted absolute phase doesn't seem to be a horrible thing for me.  Time to install the GE's again...

I installed a pair of GE's on my negative speaker posts and listened again.  Again, the sound seemed to change similarly to when I installed them on the positive speaker posts with the phase inverted.  I could hear slightly increased clarity, a more quiet background, slightly more defined bass, and increased separation and sense of space.

Totally confused by all of this, and frankly a little sick and tired of messing with all of this, I decided to just listen.  The sound is really good, but I had really good before.  However, it is now a couple of days later and I sat down to listen for a while.  The sound is amazingly good.  It's one of those deals where I can just let the music play regardless of what's on.  Everything sounds really great.  I would say it's better than what I had before the GE's.

Big picture, I'm still VERY confused.  Are my speakers now running inverted absolute phase or not?  This I find a bit upsetting.  I need to figure this out.  I also need to play with the other GE's I have, I'm just not in the mood for now.

I've never actually measured, but my guess is that there is no measurable attenuation.  I think the "attenuation" you hear is more a timing thing that makes your brain perceive as attenuation. 

Also, if you hear attenuation, try switching the GE's to the positive speaker post if you are using them on the negative currently. 

For the record, mine are all gone.

TJHUB,

I'm so late to the party, it's probably over!  However, I want to share a thought with you on your experience regarding the phase inversion.

First, is your source strictly CD/SACD/DVDA based?  If so, this may explain why you preferred the sound phase inverted.  I was recently informed that approximately 90% of all CDs, SACDs, DVDs, etc. are phase inverted.  So, if your system has correct phase throughout, you will get the best sound by inverting the phase in your system as this will correct the inverted phase from the source material.  I recently made this change and can't believe how much better the vast majority of my CDs and SACDs sound.

I'm getting ready to order some EVS Ground Enhancers and was contemplating which speaker terminal to attach them to, positive or negative.  You may have already done the ground work, but I guess I'll have to try them both ways as well.  Now, if I can just figure out how to order these things.  I don't find any way to do so on their website, and there isn't any phone number to call.  Does one just send them an e-mail?

Cheers,
Dean

Would you mind posting back if/when you get a response?

I e-mailed a month ago & have PM'd Ric Shultz here...but so far can't reach anyone to place an EVS order.

TJHUB,

I'm so late to the party, it's probably over!  However, I want to share a thought with you on your experience regarding the phase inversion.

First, is your source strictly CD/SACD/DVDA based?  If so, this may explain why you preferred the sound phase inverted.  I was recently informed that approximately 90% of all CDs, SACDs, DVDs, etc. are phase inverted.  So, if your system has correct phase throughout, you will get the best sound by inverting the phase in your system as this will correct the inverted phase from the source material.  I recently made this change and can't believe how much better the vast majority of my CDs and SACDs sound.

I'm getting ready to order some EVS Ground Enhancers and was contemplating which speaker terminal to attach them to, positive or negative.  You may have already done the ground work, but I guess I'll have to try them both ways as well.  Now, if I can just figure out how to order these things.  I don't find any way to do so on their website, and there isn't any phone number to call.  Does one just send them an e-mail?

Cheers,
Dean

Dean,

Yes, you are VERY late to the party!  I actually gave up the the ground enhancers because I just could not get a sound from them that I'd call "better."  There is no doubt that they affected the sound.  One way more negatively than the other.  I ended up giving one set away and the other is at a friend's home since about July of the year, and I think he has yet to try them.  I'll be seeing him this weekend.  If you are interested in a pair of these in new condition, PM me. 

On the absolute phase inversion, I still haven't figured it out.  I tried the AA battery trick, and I could not determine which way the driver was moving.  So I just gave up.  I recently received a new DAC that has a phase inversion button (very cool).  When I use the tube output, I have to invert the phase to get the proper, coherent, center image.  If I leave the phase "normal," the center image is clearly smeared.  I haven't really figured that one out yet either, but as things are sounding really great, I don't care either.  I hope one day to understand all of this.

Gooberdude, etc.
My regular email address is my paypal account address (ricevs@comcast.net).  That info is also on the main page for the GEs.  If you cannot figure out the pricing then let me know.  I can also send you a paypal invoice.

Thx Ric

It has to be 45 days or so ago now, but I pm'd you here & sent an e-mail to your comcast address.

No worries though.  I'll be in touch.  In no hurry as I made some enhancers which are ok, but not as good as the evs you sell.

heck, i'm still waiting for the crystals wraps you have on your website.  My x-overs are covered in maher's crystals & I'm game to try other iterations.

I must say Ric came up with a brilliant marketing strategy.  Price it at $30...a price that many will say what the hey and send him the $$.  Some will hear an improvement, many won't but the latter group will say returning ain't worth it for the measly $30.  The cost of construction in Ric's basement couldn't be more than...what?...10 cents, if that.  Very smart marketing strategy, very smart indeed..but what makes it even more ingenious, he apparently doesn't even bother returning messages....brilliant.  Hats off to ya Ric!  :thumb:

I tried the version which just adds a piece of wire to the speaker ground side but did not really hear a difference however the version that uses a battery and a cap was a different matter. I connect this to the grounded chassis plate of my tube preamp and it makes a nice difference. Quieter background with more details.

It is called the Battery Ground Tweak(BGT).
