ERS uses

bubba966 · « **on:** 22 Nov 2003, 03:06 pm »

Ok, I've not had a chance to do anything with ERS yet, other than having a digital fully wrapped with ERS tape. At some point I'll be getting some.

But what to do with it?

I've heard that around digital & power is good. Around analog apparently doesn't work so swell.

But I'm looking for very specific & interesting possible applications.

Has anyone tried the innards of a video display? How about a speaker enclosure?

So list what you have tried, and what you're planning on trying. But most imprtantly, be as specific as you possibly can!

Thus far I've done a 5" square on the top of the inside of my Sony DVP S7700 transport directly over the aluminum looking plate where the disc spins. Also done the inside of my tubedac and power supply. Finally I had a small square so I cut it in half and wrapped a peice around the BNC barrel of my HDXV digital cable. Thus far I'm very happy with the results.

I've got one sheet left and was thinking of posting a very similar topic to see where else people have gotten good use of the ERS - thanks for taking care of it for me!!

Inside Transports - over the uproc clock nets - very good result

Inside DAC - very bad result

Inside preamp - very bad result

Based on the ERS thread in the critics circle and since I had to be inside my Powervar and Oneac transformers anyway (now that I've found a pair that are DEAD quiet - no transformer hum AT ALL!!) I placed a strip on the back of each of the outlets, of course making sure that the sides of the ERS weren't touching anything. I also placed a strip on the cover of the units directly over the top of the transformers. Results - quiet, quiet, quiet, quiet. Another level of "blackness" that the music just comes out of. Based on this I'll probably take apart my PS Audio ultimate outlet, ernie's po-box and also cut a couple strips for my wall plate as well.

OK, question. I was thinking about this as I sat and listened to the differneces to my system. According to Stillpoints web site ERS "ers redirects, absorbs, and diffuses EMI/RFI frequencies". redirects and diffuses I understand, no problems there. However, absorbtion - where does it go? EMI/RFI has to turn into something else or it would get saturated right? So, what then, heat, light, liquid, solid, gas -

Thanks!

I cut out a 2 1/2" circle of ERS and punched out a 3/4" hole dead center so's to fit over the inner plastic ring of the WBT terminals on my Lorelei's. I plan on doing someting along the same lines for my Nemisis center speakers. Excellent tweak! I also lined the inside casing of my Motorola 4DTV satellite receiver by cutting a zillion slivers of ERS to fit between all the vents , both on the sides and top. A royal pain in the @@s but a major worthwhile tweak as my picture quality both on analog/digital improved plus there was a slight improvement in diital audio. I went back and forth for over a month with a sheet under my 4DTV before gaining the courage to do this. (my first application of ERS) My Yamaha digital 6.1 receiver was next and all tho there was a clear clarity improvement, I probably overdid it by covering the sides and top as I had with the 4DTV. The Yamaha had been fatiguing to listen to at high volume anyways but after ERS, the clarity brilliance was just too much. Sounded awesome at lower volumes tho,,, sold it with my Bose, which also had ERS applied to their terminals. My BPT, now what can I say that I haven't already said elsewhere? Well, maybe 8 sheets internally with 3 more to go! This tweak kicks major @@S. I have no doubts that it was a big part of BPT's success in their new Signature flagship as that torridal is a hotbed for EMI. I went by the pictures at 6moons along with talking to Chris Hoff as to where to place ERS and how much. Other possible places,,,, Bybee's!!! I know that Jack Bybee has already wrapped them with ERS. Even he knows that ERS will complement the little buggers. Wrap them again! Can you use too much on them? Not likely I'm afraid, just like you can't use enough Bybee's in the audio/video chain. Yeah right!

It's MY opinion and I'm sticking with it. And with that,,,,, I'm done. (til you guys give me more ideas

) Regards, Robin

Some questions:

Audioengr - You stated that the results were less than expected involving your DAC and Preamp. What was bad? Did the sound become too etched?

Robin - You are truly a sick puppy to have the patience to cut up microstrips for your dish receiver. When I get my fresh supply I'll get right on it!

It appears from what I've experienced and what I've read from other tweekers that the ERS can be used with relative impunity on all power related applications (eg. within power conditioning units, over and around transformers, over power input cables, as a cover for receptacles, etc)

I used this product extensively in my Modwright modded Sony 9000ES.
I covered the interior front half of the top cover, taped the transformer as best I could and added a cantilevered piece 2" above the digital board. I avoided putting anything over the analog section per Dan Wright's suggestion. This resulted in a sound that in my system, walks a thin line (successfully) with being too detailed. If you use this product, be aware that you don't necessarily have to totally cover a given area you want to treat. A piece half the size may do the trick. Put in a piece then listen. Don't worry about the effects being too subtle to detect. You''ll hear them! Add to the tweek in successive steps until the etched effect becomes too prominent. Then back off. As I've stated before, the ERS seems to take the euphonics out of your system.

I was thinking of treating my Marantz AV receiver, but after reading all the comments it looks like I'll just treat the transformer and power lines and maybe a small piece over the digital board. I will certainly not line the sides and cover like I did with the Sony. I don't want my ears to bleed!

At any rate, it's probably pretty system dependant as to where and how much to use. Start slow and gradually build it up until your eardrums start to ring.

No, it was definitely rolled-off. Similar to my experience with other filters, such as Bybees.

I disagree, really I do. You may sell your Bybee rolloff but ERS rolls off the highs too? Now that's a major joke to my ears. No negativity intended here Audioengr as with other AC members towards your comments but I guess I'll go with my ears vs the wall of patents thank you. Regards, Robin

I've got to side with Robin on this one. If there's one thing that this product does NOT do is to dull the sound. Perhaps the ERS was placed over analog circuits which is not recommended.

Because of Audioengr's comments, I put off not doing my Sony ns-700 til this week and did them now. This included an IEC terminal installation with a Acme silver plated cryoed IEC terminal w/ a VenHaus flavor 2 power cord. After cutting the power cord 2" from the circuitboard clip and crimping quick disconnect clips for the IEC terminal, I wrapped both leads with about 1/2 dozen truns of ERS. I then placed dampening vinyl across the length of the upper casing and far enough back as not to touch the circuitboards for the RCA connections in the back. I was also able to place a small strip of Dampening vinyl on each side. To ALL the dampening material, I placed Stillpoints ERS all tho in one spot I had to go back and cover with electrical tape as I noticed a ribbon cable that might have had contact with the ERS. Why take chances?

Well, when it was all said and done, I must say that the bolt holes were a little off. But not so much so that I had any problem threading the screws back in place. I am right now rocking to Nathan's Metal Sampler. I will say that at first listen before this mo, I wasn't all that moved my the music but then I only gave it a listen once. I cansay that at this second listening, the music is much more appealing. The lyrics are much more understandable (a f***ing miracle) and if this CD isn't fatiguing for me, none will be.

Not only are the lyrics more comprenable, everything is more pronounced, clarifyable with a noticable lack of grunge that had been brought out from the introduction of my recently new Ridge Street digital cable w/ 2 silver Bybee's. So there you have it, Bybee's in the digital cable & ERS in the DVD player with the results of increased dynamics/micro details and a decrease in the grunge department. I haven't witnessed any downsides at this point, the only ones that I was expecting anyways were a fatiguing brightness from using too much. At this point, that doesn't seem to be the case. If it had been, I surely would have gotten out the electrical tape. I still may after putting some miles on this mild mod. But for the time and materials spent, time well spent! Regards, Robin

OK, had to reopen the power conditioners today after looking at the 6Moons review of the BPT and reading some more of your posts. Since I did I took some pictures of where I put the ERS and created this gallery - http://www.audiocircle.com/index.php?action=gallery;area=browse;album=139 -with them.

Well??? You gonna let us know how the ERS power applications went? Good, bad, ugly, what?

Oh! Sorry, I kinda forgot. My wife was telling me to get off the damn computer and pick out a movie!

With the additional ERS around the Powervar cabling and the two "black boxes" and in the UO, things just get quieter. Like I said on the first page, it's just quiet now. And after listening to a selection of stuff (briefly before the movie

) I noticed a wider soundstage and more detail, but no loss in the presentation of emotion and realism.

Really, for me, a great tweak in the power equipment, at least as good as in the transport, actually better. Now, hopefully we can get some others to post results so I can try this stuff other places! I'd try tackling the Denon 3802 pre/pro but I'm not so sure I want to disconnect everything from the back of it!!

Hea, I know what you mean about connections as I'm taking apart my Sunfire TG3 processor next week to replace an Acme cryoed IEC terminal that DedicatedAudio gave me with a Furutech Fl-10 Rhodium IEC terminal w/screwdown connections that Chris VenHaus gave me. A regular IEC shootout!

I'm also going to cover some of the ERS that I previously installed with dampening vinyl, for experimental purposes as I never listened to my processor without the ERS. Let's say I crossed the finish line before starting the race. As far as ERS in my BPT, I had an incredible (love that word

) clarity improvement in the highs and midrange. I'll be going back in there also to visit the Bybee's with more ERS. Like stuffing a turkey from the outside? And I think I'll visit my dedicated outlet box with some ERS,why not?

Regards, Robin

Steve, are you still using Stillpoints ERS in your Sony DVP-S7700 modifications like you had been doing all summer?

I have tried ERS in a number of places and I find that in most applications it does reduce dynamic impact, dulls transients and rolls off the top end.

I have found this effect when wrapping ICs, putting on transformers, on top of components. In my DAC it had the negative effects placed almost everywhere. I did find a positive improvement when I placed a credit card sized piece over the ICs in my Audio Note DAC. So this was mostly on the digital circuitry in the unit. The improvements were lowered noise floor, more ease and pace to the sound, less glare.

I also like the improvement to my Monarchy Audio DIP classic digital filter. So I feel it improves digital circuits, but harms analog and power supplies.

satfrat · « **Reply #19 on:** 28 Nov 2003, 06:56 am »

Tucker, when you say power supplies, are you talking about component transformers or power conditioners also? Personally I've stayed away from all cables and analog components, but with all the places I have used ERS, I seem to find/hear just the opposite of your findings. Another difference of opinion here, hea? Who would have thunk it possible,,,

BTW, have you tried Zcable's Z-sleeves yet? Regards, Robin
