Title: Exotica 3's customized to the max
Post by: jsalk on 3 Nov 2014, 09:17 pm
We have a friend who shall remain unnamed (Pete didn't want me to indicate these were his new Exoticas).  While we were in the process of designing the Exotica 3's, he had plenty of time to explore design ideas.  So he designed a rather novel set of cabinets and turned the project over to us to execute.

He wanted separate cabinets for the woofer section and the midrange/tweeter section.  He wanted textured copper on the front baffles and had a sheet of raw textured copper sent to us.  He specified everything down to the outriggers, feet, binding posts, etc.

While it may look simple, this was probably one of the most complicated builds we had ever done.  Working with the copper was very tricky, so we had to work slow.

Here are the results...

Here's a side shot...

And a shot from the rear...

On Friday (Halloween), Pete and Brenda showed up with cases Pete had built for the tops, bottoms and outriggers - each appropriately sized and labeled.

While this pair required a lot of extra labor and we wouldn't necessarily want to duplicate again, it was fun to see if we could turn Pete's dream into reality.

Happy listening (name withheld upon request)...

I don't see what took so long on those baffles...you mean it took more than a pair of Tin Snips and a couple of cold ones?  Kidding of course!

I was wondering if these mythical beasts would ever see the light of day.  No more wondering!

Not sure where to start.  Have not come to the realization that they are really my speakers.  Sure, they're sitting in my house, but they are surreal.  Huge kudos to the team for putting up with my request and having to work way outside the standard process flow.

Took a quick shot of the team on Friday posing with the speakers.  Missing is Robert, who left early for Halloween activities.

Yes.  ViaBlue spikes into a different brand cup (larger).  The left is matched to the left and vice versa due to tolerances of locating the spikes, recesses in the bass modules, and then gluing in of the cups.  I have the bas modules labeled as right and left now.

I spent a ton, and I mean a ton, of time sketching, buying copper samples, researching paints, finding all the detail parts for this project.  Started really getting into the design phase in late June.  I downloaded a CAD program and designed the baseplate, etc.

Now that's a finish! Veneer? pffft. Now we're talking up to date, styling, worthy of a modern home and something that makes Jim a badass.
Thanks.  I tried to find a veneer that was different or worthy but just came up with the same boring results.  One day when I was agonizing over the finish I spouted out that I really wanted copper....and that was it!  I grew up in a copper family - my dad was a 40 year Revere Copper & Brass R&D employee, we had copper everywhere.  Grew up standing on roofs installing copper snow flashing with my dad, learned to solder and braze at 10 years.  My grandfather, who I never met, made copper stills on the side for extra cash in the 30's.  So why the heck not.

My original paint idea was black as I thought it was the perfect match.  But I have always wanted white and a more modern look, so my wife, who has a styling eye, encouraged me to go white.

Looked at every automotive paint in any shade of white there was and finally we chose by process of elimination in both indoor and outdoor lighting, a Hyundai tri-coat metallic white.  Not too white and not too yellow or gray.

Found anniversary edition WBT's in white.

Provided copper colored cable sleeving.

Bought solid copper balls for the feet.  Drilled them, tapped them, inserted stainless set screws, and polished, polished, and polished some more.  Then sealed them in clear.  (good excuse to buy that new bench grinder)

Base-plates are 3/8" hot rolled steel.  Had them plasma cut.  Drilled and tapped them (not easy with hot rolled), sanded them, primed them, and painted them - twice.  The steel plates alone are over 20 lbs. each before copper.

The team also made me grills which I was not expecting.  They also made me white standard plinths for back-ups.  My crates fit perfectly and provided 100% assurance no damage would occur during that 3 hour drive and handling.

The system is getting overhauled and 1/2 of it has begun - new amps, speaker cables, power conditioner.  Can't wait for everything to come together this week.  Friday is a vacation day!

OK, I'll be the one to ask the obvious question -- what amps, cables and power conditioner are you gonna mate with your new speakers?

Post by: Big Red Machine on 4 Nov 2014, 02:53 am
I wanted Class A and my RMAF searching led me to tubed amps first, but finally I zeroed in on solid state (for many technical reasons).  My two top contenders were Pass XA30.8 and Electrocompaniet anything.  I ended up with EC AW180 mono blocks.  Should be plenty of power for 92 db upper cabinets.

Bought some Acoustic Zen Hologram 6 foot SC's in great condition - highly rated.

Looked for a Velocitor at my price but could not make the deal so I went with an Acoustic Revive RTP-4.  That should be here Wednesday.

Am reworking my outlet box with Maestros and Furutechs and some tourmaline crystals to try and keep up with the RTP-4.

And for kicks I made matching copper sleeved power cables for the bass modules.

In 2015 I am looking at dacs and preamps and if the AZ cables show promise then either more AZ IC's or perhaps High Fidelity IC's.

I was going to buy Electrocompaniet at one point.  Have NCores and a Ultimate 70 (with XF2 Mullard EL34s).  I will go back to Electrocompaniet if the 1625 amps don't work out on my Exoticas.  110 Watts per channel from 4 1625 tubes.  I am looking for speaker cables.  Currently using Synergistic Research Tesla Accelerators, but they are short (8 feet), I need to get 10, so I am on the lookout.  I am using a Lampizator Big 7 Dac, Dave's Cables, a Tortuga LDR (this will be the next change I think) and a headless MacMini with an LPS.   

I am in the process of figuring out power.  I have built a few 12 volt trigger boxes that I am currently using (fed off of an UberBuss).  I have never really heard much difference with power, so I am not sure where I want to go here.  I also picked up a WattBox IP controlled power strip.  Thinking I may use that.

Hey BRM,

Would you mind sharing your thoughts on the need or desire to have the tweeter/midrange in separate cabinets. When I read that you were planning on doing this I guess I was expecting a little more drastic change to the design, but it looks like a standard E3 cabinets with just a little space in between.

I think it was a good call on going with the white!

Simple:  I wanted to keep the weight down for moving them.  Sure, I end up with 4 pieces, but I kept the size and weight down to where I can move them w/o blowing out my back.  And they fit into vehicles better, even in the crates.

Was there any thought that the speaker would perform better?  Not really.  I actually anticipated the upper rattling due to the lower energy but that has not occured and my backup plan was to change to a thick piece of foam between them if need be (plenty of extra from the shipping crate build).

I wanted the smallest crack between them and we got pretty close - there is a brow on the upper hiding the recessed spikes.  I also wanted very sharp edges all around for a super modern look but Jim talked me out of it for acoustic reasons.  As it turns out the cabinets are different dimensions than the one piece because the volume relationships between the upper section and lower section change when they are not integral.  So I had to go back and modify my baseplate design to take on the deeper cabinet dimension.

Everything about this build was custom except the drivers and crossover!

Pete, congrats on those amazing speakers! 

Can I ask you to belabor the amp search a bit more?  I'm considering PrimaLuna HP power amp with KT120s, which if run as a mono block, would provide 90 watts in triode mode (appx double if put in ultra linear).  These are about $8k/pr.

The Parasound JC1 can provide up to 10W/25W Class A if set to low/high bias mode.  Did this not make the short list?

Thanks for any input.  Enjoy! Jon

I read alot.  Bunches of reviews online including archives in Audiogon, Audio Asylum, here, etc.  I look for trends in analyses, watch for blowhards, and try to sift for honest assessments and then draw conclusions.  When you see repeated comments from different sources postively or negatively about a certain product then you start to feel good about working your way through the funnel.

My first choice was a set of used Lamm ML1.1's at 90 watts in Class A but the darned tubes take a beating and glow like toasters.  Plenty of power for 92 db, very highly rated, and for the most part reliable units.  I had lots of encouragement at RMAF to go tubes but the more I looked, the more I saw reliability and longevity the issue with Class A tubes (and sockets).  I hate to say I am lazy, because I don't believe I am, but it is a heck of a lot easier to own Class A in solid state form.

Can't comment on PrimaLuna, but if I was looking at tubes I'd contact Hugh and look at the Melody gear as well.  As for Parasound, very good company, great crew, but the common theme I read was that while powerful, they are consistently lean sounding.

In comparison, everything I found about the new Pass .8 series was exceedingly positive (and you need to sift through the fanboyism) but I was a little concerned that even up to 60 watts Class A was going to be barely enough headroom.  The larger amps were out of my price range.

Everything, and I mean everything I found out about EC gear was positive.  "Tube like", "smooth", "powerful" were consistent themes.  I spoke with the EC sales rep at RMAF and was inspired by their thoroughness outside of the independent reviews I did before and after the show.  I also contacted customer service and inquired about circuitry changes over time and how to tell one model from the next - very little has changed in their designs.  List on those 180's is now $5800 each.  I found 2 pair for sale and actually bought the more expensive pair in the states, with a warranty no less, for a very good cash price.  It was kind of a no-brainer to give them a try and be future-proof in the power output stat.

Class A will also reduce the need to power up my space heater in my basement as well! ha  These monos are 48 lbs. each as well.  Hello chiropractor.

Well Big'un you certainly have outdone you're self this time !  :thumb:

I have had interest in upgrading for about a year now and with the development of Exotica 3's I have been waiting to see yours and the others since the prototype introduction.
You truly have a unique styled pair, the copper is one of a kind I'm sure. My vote from the first was on the 2-cabinet design, base on convenience of weight and mobility. The single cabinet is fine, depending on cost difference it still maybe the optimum choice. However when you are spending this much its best to get what you want ! I am very impressed with you're attention to detail with the associated parts of the speaker, very well done! :thumb:

I guess the biggest surprise to me is the choice of the amp. I have never had the opportunity to hear the  Electrocompaniet  equipment but I am aware of the brands very good reputation. I will have to agree with your choice of solid state over tubes, not that the "tube sound" is inferior to Solid State, its my realization that playing with tubes would not be my game after the newness of the experience was over ( that a personal reflection knowing myself). But a significant point is when SS amps go beyond the typical designs, offering advanced technology, such as (low to none)  feedback implemented to the different stages of the amp for one, puts this Solid State amp in a different league. The reported sound character of the EC AW180 mono blocks uses terms like accurate, realistic upper bass / lower midrange, excellent reproduction of acoustic music. The reproduction of Horns, Cello, wood instr. and piano are reported to be wonderful. Also the report that the amp does not give the "front Row effect", that is it doesn't force the forward feeling of being in the front row but rather puts you where the recording intends. Now I have not idea if these stated reflections of the amp sounds are typical hype or are a truthful, agreeable, nature of its sound. BUT I can't think of a better assessment where a SS amp needs improvement. This amp should go great with the stated qualities of the Exotica drivers!

Anyway sorry for the long drawnout post but I must admit I am very impress with your new system and would love to hear it.

Wow, those are just stunning.  Love the idea of a class A amp for the uppers.  I think that makes a ton of sense with the powered lower section.

Any anticipated acoustic impact of the copper on the front?

While I'm no longer using Butler Audio, they make an unreal Hybrid Tube/Solid state amp called the Monad's that are pretty darn trick also.  You know... in case you get an itch down the road.

Stunning speakers and attention to detail by all involved.  Very, very nice!

From the amp/ speaker connections doe it travel to the upper box or does it feed into the bass amp?

thanks

The signal goes up I believe, but if you turn off the bass module, the upper will still play like a monitor.  Ask me how I know this. :duh:
Title: Re: Exotica 3's customized to the max
Post by: Vulcan00 on 5 Nov 2014, 08:42 pm
I suppose you know because you tried it?

But does it feed the bass amp module first, then out to the upper box ( tweeter / mid range). Or does it feed from amp/speaker connections to both?

But does it feed the bass amp module first, then out to the upper box ( tweeter / mid range). Or does it feed from amp/speaker connections to both?

It seems like there would only be one option here.  The amplified signal for the upper cabinet enters at the speaker posts and travels up through the connector that links the bottom and top cabinets.  This signal would not have anything to do with the built in amp.  The amp should receive its (non-amplified) signal through the XLR input and then amplify that signal and send it to the woofers in the lower box.  Did I get that right??  Just my thoughts from looking at the photo.
Title: Re: Exotica 3's customized to the max
Post by: sfox7076 on 6 Nov 2014, 02:36 am
Nope.  The amp receives the signal from the binding posts.  The amp is internally connected to the binding posts.  A separate wire goes from the binding posts to the cross over for the umbilical I imagine.  Mine is internal in the cabinet.
Title: Re: Exotica 3's customized to the max

I hadn't thought about the crossover--I was thinking in separate powered subwoofer terms.  Doesn't the amp need an un-amplified signal?  How does that work from the binding posts?  Didn't mean to derail the thread with technicalities.  :D

On another note...BRM, who did the metal work for the bases?  When Jim built my custom sub a while back, I used a third party to build a metal base, so just curious what you did.

I had a company that I have used several times cut my parts for me.  I did not use Jim for the baseplates.

On a sound note, the EC amps are AUTHORITATIVE, OUT OF THE WAY, SMOOTH, CLEAR!

The speakers sound 10 times better than I heard them at Axpona or RMAF.  They absolutely can play with such clarity and imaging in my system it is just astounding.  At the shows I would not have put these in the same league as some of the $50k+ speakers, but hearing what they can do in my system, I am thoroughly convinced they are competing with some very expensive designs.  I have shaken the rafters w/o even trying and had instruments laid out in very segregated placements from left to right that I am experiencing familiar music on a new level.  The "realness" of voices and instruments is spooky.  I said the SS8's were different.  They are different animals, but the E3's are wayyyyy better.  Hands down.

Doesn't the amp need an un-amplified signal?  How does that work from the binding posts?

I assume that with the proper circuitry and a very high input impedance sub amplifier, the sub can derive its input signal from the speaker input with negligible loading, just like the REL subwoofers do.

I'm using my brothers powered subwoofer with my HT3's. You can hook it up either way. I bought cables and use a line out from my preamp, my brother  hooks it up with the amplified signal from the speaker leads. On the Rythmic website you can see a closeup of the amp with the different options for hook-up.

Awesome Pete!

Post by: sfox7076 on 6 Nov 2014, 02:57 pm
Not to contradict you, but if you hook the sub up by LFE in and the speaker cables on these, the second the signal hits the amp, the sub will likely blow.  You would have double signal coming in below the crossover point in your receiver.  DO NOT DO THIS WITH EXOTICA 3s.  That is all.

Sorry if I confused anyone. I was simply trying to explain that on many powered sub woofers you have the option to hook up either way, Line Out, or the powered speaker leads from the main amp.

For sure, don't take your Exoticas apart and rewire them, just use the speakers connections provided.

Post by: jsalk on 6 Nov 2014, 04:48 pm
Just to make things clear, this model Rythmik plate amp has two line-level inputs - RCA and mini-XLR - but no external speaker level inputs.

When we designed the Extocia 3's, we did not want to require the owner to use an additional line-level input to the woofer section.  So we tapped into the amplifier internally to provide a speaker-level input.

The result is that the amplifier signal applied to the binding posts feeds both the crossover for the midrange and tweeter as well as the speaker level input to the amp.  When used in this fashion, you cannot use the line-level inputs to the woofer section at the same time.  If you did, the output of your amp would be feeding the output of your preamp and disaster would likely result.

It would seem that it might be a good idea to internally disable the line inputs to avoid the possibility of someone with a combination stereo/HT setup connecting an HT LFE output to them.  Perhaps a rare scenario, but .....

It sounds like you should deactivate the input on the amp so someone down the road couldn't make that mistake.

We ship these speakers with cages over all inputs and adjustments.  So the user would have to go to great lengths to remove the cage to gain access to those inputs.  We don't expect any of our owners to do that since there are no controls (other than perhaps gain) which should ever be changed.

Since Pete supplied the plates, footers, binding posts, finish and a large sheet of raw textured copper, I don't know what costs were involved with those parts.  But I would guess that the price would be around $15,000 when all was said and done.

Can't say it is a problem.  The shelf is 24" deep and the speaker backs are 11 inches from it.  The way I look at it is sound will blow right through the open cavities so it is invisible to the speaker performance.  Certainly no bass build up due to the shelves.

Eventually I will run some sweeps which should be interesting with these beasts.

I called him yesterday to thank him for such wonderful speakers.  I did mention that compared to RMAF, my setup is bringing out a level of sound that I only thought possible in rooms like Von Schweikert and Focal at the show.  Pretty close to the VS room and in the same "family" of sound as the Focal (ease of delivery with a kick you in the balls result).  Redbook never sounded so good in my world, ever.  96/24 is sublime.

No way man...I bet your system is doing wonders for the lower syth bass, pipe organ, percussion, double bass, tuba, etc. Two 8's per side with 600W a side. With the servo controll I bet they kick like some 12's on the right tunes. Oh, you are playing low bass, LOL! The best of both worlds I guess. I'm sure other 2 ch/no sub purist will be envious when they hear the clean low bass they've been missing.

Amazing design choice. Congrats!!!

Lack of remote control is wearing on me, but the damn preamp is so awesome.  I am considering many options including a Bent or perhaps a dac that acts like a preamp (although many who do this miss the preamp in the chain).  But I'll tell you what, it sounds mighty fine.  Now if I can swing some High Fidelity cables to try....

I think they are as they only have balanced inputs.  Work great single ended though.  If the Bent were better I would definitely get a balanced version.  Don't like that you can only get the gold case and not the black or some other color.  I actually think a solid state EC pre might also be a good choice.

In the mean time, I have deployed QRT's, PEA's, and Pulse Gen Zx to wicked effect.  Amazing elimination of sibilance and also bass tightening.  You've got to try these!

And in my hunt for absolute quiet background I have also ordered a Total Dac USB cable to see if my source of noise is digital.  If that doesn't work then I'll be going down the re-generator path.

And to add that final touch to the speakers, Jim has had a conversation with the owner of Seas and now I have solid copper phase plugs to match my speaker finish instead of the wood plugs in the Exotica drivers.

Remove the driver and the screw holding it goes all the way through from the back side of the magnet out into the cone side.

Okay, installed my new TotalDac USB cable which just arrived via FedEx from France.  One of those: what the hell is that, oh wow, ooh didn't know that was there, interesting, is that more separation, not sure, maybe some more hours are needed,.....hopeful.

It is always a shock to your body to hear so much change from a single cable.  When I updated to Acoustic Zen cables I heard a nice improvement, but not a shock.

I didn't know a digital cable could make such a change to the bass.  Now I have only just plugged it in and have one whole hour on it but immediately I thought the top end was extinguished for the worse.  No edgy attack.  Way more laid back.  Soft even.  The bass came alive and instead of breaking up on deep notes they held up with even more power.

The more I listened the more moments of quiet I heard between notes and the more real some things sounded - electric guitars, female vocals, saxophone.

Maybe Vincent is really onto something with his filter network.  I need more time because it feels like much of the top end is smoothed out but maybe that is hash.  I might need to up the volume one more click to compensate.

Lack of remote control is wearing on me, but the damn preamp is so awesome.  I am considering many options including a Bent or perhaps a dac that acts like a preamp (although many who do this miss the preamp in the chain).  But I'll tell you what, it sounds mighty fine.  Now if I can swing some High Fidelity cables to try....

Wow Pete, fabulous design and way to go Salk team

Since you are no longer in the vinyl stage look at the new Doshi linestage

The prior full function Aalap totally transformed my system, it has a phono and line stage that many say is second to none or at least not without spending totally stupid money

Nick Doshi is out of Virginia but Larry Marcus at Paragon Sight and Sound in Ann Arbor is his Exclusive rep. Just incredible and the new line stage has a remote. This is a different league.  Doshiaudio.com


As far as cables, i have AZ holograms and Satori Shotgun. Now relegated to my ht. Very nice and tonally correct.  I tried out a modestly priced cable - Crimson Audio out of Austin texas from buzz I read on Audiogon. I am generally one to never buy cables new, but I am so glad I did. Creston Funk is great and they have incredible prescence. The ICs are great too.  They dont look like much and are not garden hoses but dont let that fool you  I've tried a lot of stuff but these are staying. Wow

Again congrats of the speakers!
Title: Re: Exotica 3's customized to the max
Post by: Big Red Machine on 25 Jan 2015, 02:35 pm
Yes, Doshi is highly regarded.

I'll check out the Crimson cables.

great to hear Pete!

you really put so much thought into those speakers and crates.

perhaps you should design crates for Jim to haul things off to shows  - with pop out wheels on bottoms

Having SS7s and SS10s,  I know having the tops isolated from the woofer drivers in the SS10s make a big difference - Jim's spare no expense approach, like your customization

As tempting as it is to have Jim take one of those exotic wood finishes, that white look with the metal inlay is so classy 



with any luck Larry might lend you out a Doshi line stage to try at home over a weekend.  A short trip to Ann Arbor - they have some great music stores and ethnic restaurants

I've been meaning to visit Larry's showroom  and see Jim again when I'm up visiting the family but I didn't go home last summer

cheers

Added power conditioning:

Most recently I had the Walker Velocitor - had an interesting effect, was way overpriced for the technology inside, and at the end of the day was a major ripoff to anyone who might have bought one brand new.  What I learned was that the QRT technology was very effective and I moved in that direction.

Tried a small Silver Circle Audio power block that was not equipped any more inside than the Felix.  It was very damaging to the sound, but did help the noise.

I started experimenting with Audio Magic Gen ZX's and PEA's to great effect.  I ended up hard wiring a Gen ZX into each monoblock, placed a small PEA over the circuit breaker (highly recommended), and then eventually put a medium PEA over each monoblock's grates as well.

The Kemp QRT's also work very well and are adjustable.  The cheapest QRT technology you can buy.

I still have a Running Springs Duke I used on the amps to great effect.  I have not tried it in combination with my latest XXX unit from Audio Magic yet.

One thing for sure is that sibilance is completely gone with AM gear and the noise level is significantly reduced.  Not 100% gone but way better than prior setups.

What's a PEA?
Title: Re: Exotica 3's customized to the max
Post by: Big Red Machine on 30 Mar 2015, 02:45 pm
A P.E.A. is:

http://www.audio-magic.com/Prod-PEA.html

It is similar to QRT (Quantum Resonance Theory) but not exactly the same.  PEAs are often referred to as Spintronics, but I am not sure that is accurate from my readings on Spintronics (still trying to wrap my head around this).  Aligning electroncs so they are all going in the same direction and therefore do not make "noise" by being chaotic is what I believe a PEA is supposed to do.  Something like that. Whatever it is, it seems to clean up the sound and in my application does not impede any flow of music.  Quite the opposite, it seems to "free up" the sound and provide more detail.

Well thanks for the explanation and the link.  I had not heard of this before.  If you place a PEA over a breaker and it aligns your electrons at that location, how does it prevent those same electrons from becoming un-aligned by the time they reach your components?

Scientists have been working on electron alignment for a long time.  It could replace binary language for computing.  Basically that would redefine the world.  But they have not been able to alighn the electron's spin outside of a ferrite core with anything small enough to work.  And once out of the core, alignment is lost.  I don't buy PEA tech.  I am glad it works for you, but to me, it is doing something else, not aligning the spin of the electrons.

Gotta find something to spend cash on right?  Gotta feed the monkey.

I tried the smallest, cheapest used one I could find and liked the result.  So I then found a pair of bigger used units and really like the results.  I'm pretty happy right now if they are spinning or not in the same direction.  It is not a subtle change that is hard to distinguish.  I'm not a subtle person and need substance for me to keep someting in the system.  Plus I am very good at finding deals so I rarely pay "new" prices.  That way I can resell and break even in the tweak category if the "science" does not pan out.  Monkey fed.

I can certainly relate to Pete's approach to evaluating equipment in his system.
My modus operandus as well.  Finding manufacters who sell direct and being patient and finding deals on used equipment.   It can seem like a merry go round at times but the effort is well worth it

I am not saying it doesn't work.  I just doubt it works the way they claim.  This is quantum physics/magno chemistry:   

http://www.nature.com/ncomms/2014/141020/ncomms6304/abs/ncomms6304.html Outside of a field, spin is gone in less than 1 second (its less than 70 microseconds at 68 degrees).

Here is a video of a lecture discussing much of the current work in the area.  https://www.youtube.com/watch?v=cID4fKraWkE  Start at 11 if you want to hear about spin in copper within a magnetic field.

Pete,

I got a Stealth Power Purifier (http://www.6moons.com/audioreviews2/bybee/1.html) from Garner.  I took a demo home from RMAF a couple of years ago and kept it.  It replaced a re-generator.  I don't care what you call it but the Bybee thingamajig works for me.  Even works on my tube amps without any power sag.  FYI, I used  to have RSA Haley and PurePower APS2000 for many years and I now have the SPP.  It cleans things up in the mid/treble without making them bright -- Just cleaner detail that is musical and non fatiguing.

An update:

The system is absolutely amazing these days.  I still use my Chord Qute EX dac and am targeting a Bricasti some day.  But for now the Chord has been stellar and I no longer have any issues interfacing with my HAL MS-2 player.

The creme-De-Le-creme piece for me has been the latest Audio Magic Stealth XXX unit in the smoked plexiglass case.  I had my clear unit upgraded by Jerry and it is stellar.

Of course I did mention previously of going to good power cables and then the Silversmith cabling - both of which stunned me and shot me way up in performance.

Now I have started implementing the Nordost Sort Kones.  Damn demo last year at Axpona left me shocked and I sat right in the front row again this year and was stunned a second time.  I went right downstairs and bought 9 of them.  First set went right under the XXX.  And yep, sounds outrageous, but they really have a cleansing effect.  I still use a Running Springs Duke for the amps, now running through the XXX.  It tightens up the bass a skosh.

Anyways, the holographic nature of my system these days is just fantastic.  I am now a hi rez download fiend because I cannot get enough.  But I have to say that redbook is absolutely stellar as well and I enjoy it equally. Go get yourself some Exoticas!

Chad Stelly at Acoustic Sounds has always used the little Qute DAC's, and he made a believer out of me with the EX... He recently upgraded to the 2 Qute, and said it is an astonishing improvement. Something to think about. Chad really gets it, and I trust his ears for sure.
