AUVA Isolators.
Release hidden detail.

“I am using a full rack of Finite Elemente for my Lamm preamp and Gryphon Essence power amp, driving Kharma DB9s speakers, now with the AUVA 100 replacing the previous shoe of IsoAcoustics GAIA. First impression is bass punch is tighter and faster. The already wide soundstage is wider, and music is more three-dimensional, with every instrument clearly more audible.”

“I’ve installed the AUVA 100s and EQs, and they are truly outstanding products. They’ve elevated the sound, which was already excellent, to an entirely new level. Products like these prove that what may seem like simple tweaks can, in fact, make a significant difference in hi-fi. I’m really enjoying the much-improved transparency, detail, articulation, and the almost spooky soundstage and imaging.”

“I’m very happy with the sound! In the meantime I’ve also bought more of your products (SmoothLAN, the record mat, and many AUVA EQs) and I’m delighted with everything. I’ll be recommending you to all of my audio friends!”

“It is like having a far more expensive system in a much larger room. Gone are a lot of perceived room modes. Bass is so much more open and detailed and deep and not muffling higher frequencies. The mids are so nice and tonally correct. The highs have totally opened up and sound far more extended without any harshness. The stereo image (which was really good) is much wider, deeper, higher. Like I said it is like having a > 100 mtr2 room. The depth is literally as if there is no wall behind the set. This transformation was unexpected.”

"The AUVA 70s replace the GAIA IIIs under my PMCs, leading to an obvious sound improvement."

"The Martin Logan Classic 9 has gone to a new home and I brought my 4 year old Kef R5 with Kef KF92 back into the room and removed the IsoAcoustic GAIA ii and installed the Stack Audio AUVA 70 to them, what a dramatic change these AUVA 70 made on these Kef R5, much better clarity from top to bottom, they are solid to the floor, no movement at all. Now working out some details to add the AUVA 50 to the kf92. well done Stack Audio... well done!"

"AUVA 50s are really good!

They replaced (in my opinion already good) Isoacoustics Gaias.  Noticeable improvement over Gaias. As if everything was cleared, all frequencies. Most notable on bass, which is less boomy, even mids are more organized. Great product!

Best description of overall effect of AUVAs on my setup I have is following. Imagine as if you upgraded your DAC to higher level."

"I ended up at Stack Audio through Hans Beekhuyzen's review. That's where I bought the AUVA 70 insolators for my Focal Sopra No.1. And the AUVA Equipment Isolator CSA2 for my Accuphase E4000. This review from Hans resulted in a larger number of orders, but they did everything they could to ensure that I did not have to wait very long for my order and that I received a small compensation for the delay.

When my order was received, I installed the insulators with the utmost care. And then let it break in. After a weekend I must say that there is indeed an improvement in the details and the sound image.
I have a 30-day money back guarantee on my order, which is great that you can try a product for a few weeks, but I will definitely keep my order. I have a feeling they will sound even better after a few more days of playing. Stack Audio indicates 5 hours of playback time."

"I am very happy with the isolators. They are very nicely manufactured & finished. The felt pads/rings seem to entirely sufficient to protect my floor, allow the speakers to be easily manipulated into position and give the speakers adequate support & isolation.
As for the sound - the difference is immediately apparent. Rise & decay time of notes are much faster, everything is cleaner or clearer. Vocals seem to have an added degree of intelligibility. Bass notes are cleaner, tighter too.
I am currently listening to Bob Marley Exodus (the album) I decided to listen to this for bass quality but what has surprised me is the quality of the highs. The intelligibility of cymbals & highs of all kinds far surpasses anything I remember hearing on this album before.
One of the first impressions I got, along with the speed of rise & decay times, was that the music had lost a certain relaxed quality and gained a certain brightness or stridency, not enough to make it fatiguing but there nevertheless. Day two, and that impression has dissipated. I still have the added clarity but the impression of stridency has gone. It is not hard to make Leonard Cohen sound relaxed but nevertheless he sounds as relaxed as ever.
Ry Cooder’s paradise & lunch, played for Ry’s gorgeous guitar is now impressing me with the quality of the bass, much tighter & cleaner than I remember. The guitar sound is just pristine.
I have attached a photo of my little system. The diffusers behind the speakers are a recent addition, only a couple of months. What was there before it was a bit home made & made the sound a bit over damped.
With nothing behind, the sound, with anything but the simplest music, would be hopelessly confused.
I now get a proper wide, deep & high soundstage, within which, the isolators have added clarity.
Anyway, don’t want to go on too much, I’m very happy with the AUVA100."

"I am actually a fan of source first, but had to invest in sound treatment because the room produced too many standing waves. After installing the panels, I experienced an increase in spatiality in all dimensions and much more transparency, I had expected that, although not to the same extend. What was surprising was the increase in dynamics. I was totally happy with my sound.

In this situation, I ordered the AUVAs for my proAc D48R's. I wanted to know if spikes could possibly be surprassed. The concept sounded promising. This time, too, my expecations were exceeded. At a much lower price than my panels, the AUVAs had a comparable effect! More three-dimensionality, transparency and dynamics! No more vibrations from loose spikes and those dynamic tight basses! My dynamic Naim components now run on steroids! Addictive! Highly recommended."

"So, to be honest on first impressions, I like the improvement but did wonder if it was enough given the cost, and would even say I may have considered a return to the Gaia's. I also had to take into consideration that I'd had to alter the speaker position slightly as AUVA 100's are much bigger than the Gaia's, but overall I like them but wasn't overly 'wowed' by them.

But, as in all things, time tells and as I had the chance to spend more time listening, then things seemed to gradually improve, building on the overall first 'OK/Good' impressions I had. So my current thoughts are, that the AUVAs really add a sense of space & depth (darker background) for the music to flow from. There is greater dimension overall and the tonal presentation is more refined.

I've also been able to hear more of a difference on a IC cable change I threw in for good measure."

"Over the past two years, I have owned a variety of isolation/coupling devices to include Stillpoints, Symposium Rollerblocks, IsoAcoustics component and Gaia speaker Isolation devices. They all made some positive improvements but they all lacked the speed and initial attack of notes and a sharper image focus that Audio Points Coupling discs and Speaker System provided.

I was quite happy with my AP until I heard about Stack Audio. The moment I replaced my AP with coupling discs to the AUVA EQ, I heard way more low-level detail, texture, more expansive soundstage width/depth and image focus was much tighter with a more impactful midbass and bass presence. Each AUVA EQ added to my DAC and Tube Pre-Amp increased my listening pleasure quite notably..

I also added the AUVA 100 Speaker Isolators a few days ago and to my surprise, they have similar attributes as the EQ; tighter/cleaner midbass/bass, more transparency, ambiance/spatial detail and a laser focused image that you can follow precisely within the soundstage.

These AUVA EQ and Speaker Isolators are the real deal and they are staying where they belong, in my system..."

"It's hard to envisage what an isolator will generally do to a random system acoustically, but in my case, it was rather simple. So I give you a specific description what actually happened, after acquiring the AUVA 100 for my Daniel Hertz M7B speakers. Generally I pick my gear very carefully, so I needed a professional isolator solution for my next step after my system was finished (I thought).

I use ultra-efficient speakers so, I thought isolator could potentially work wonders in my system in the long run. But Mark Levinson told me by having a conversation with him, that I shouldn't expect too much from any isolator under his speakers... in the end my experience said otherwise.

My primitive 1st gen. plan was plain simple: raise the speaker cabinet to a small amount, so my robot vacuum would fit around the edges of the speaker without to scratch my piano black finishing, without losing musicality... okey, check mark.

But I was still curious if their claims about AUVA isolator has any benefits, so I listened carefully, and to my big surprise, the overall sound signature gained a deep background from nowhere. I was floored. Probably the resonance-reduction towards floor & back gave the cone vibration the remaining extra movement to enhance the total effectivity of the speakers.

At least that's my interpretation of the outcome. So no energy loss present from the cabinet vs. wood floor interactions anymore.

What else? Soundstage got deeper and the whole presentation gained something magical, the MUSIC CAME TOGETHER finally and I was able to let alone my weird idea to upgrade my amplifier again & again. It is not necessary, my plan is to enhance my current system to maximum potential with small tweaks like this. Of course, I have to admit ML is also right, to reach such changes (or even bigger) it is also possible to change amplification which has speaker-specific fine-tuning.

There are many ways to influence sound in domentic environments.

Highend system building is a fancy game, You either love to do it by finding a way to reproduce your music collection in a satisfactory manner, or you will always seek for something better and you will unable to find your ultimate peace in this hobby.

A hobby should be fun, and I found my end destination with my system, and AUVA 100 helped me to calm down, sit back, and forget about upgrades. My system has been completed, this isolator was the missing piece. I'm there... no major issue found for my ambitious audible taste anymore.

Please keep in mind, that I possess absolute hearing: 18K Hz not a problem for me... Stack Audio, thank You guys. Your flexibility & kindness towards customers is unmatched in my humble opinion."

"I had my Revel Ultima Salon 2 with the Gaia1 and have now switched to the Stack Audio AUVA's 100 and... I am really pleased, much better stage/image and the information clearer and more detailed, more natural sound."

“I received the AUVA 100, unpacked and installed them. Already from the first listening session I immediately experienced the difference between speakers with or without AUVA. What shall I say? Just Wow, it’s amazing! Really impressing. You will find a picture in attach. If you need you can use it. Thank you for your support. "

Speakers: ATC SCM 50 ASLT.”

"The AUVA isolators and I had the first listening session together with my wife. What shall I say, I had expected a good performance but not at this degree! Yesterday we were listening to four tracks which we know very well. Today, with the new equipment we were fascinated after the first few seconds of the first track (last movement of Franz Schubert’s octet for clarinet, bassoon, horn and strings in F major D. 803 with Gidon Kremer and friends). As you know my speakers are very good, but in the past we never heard this music as detailed and exactly located in a well defined space.Same experience with Dvorak’s 8th symphony, first movement (London Symphony Orchestra with István Kertesz 96kHz/24bit) and Gustav Mahler’s 5th symphony in a 192/24 recording (Duisburg Phil. , Jonathan Darlington): here the complex parts, often in fortissimo, got transparent as never before heard. Also the specific colours of the woodwinds were better than before. Last track was John Adams’ Short Ride in a Fast Machine with San Francisco SO and Michael Tilson Thomas (96/24), which became a “firework”! We thank you very much for having solved the problem of dampening the speakers whilst giving them enough stability. We are really enthusiastic with the AUVAs and we are sure that we will have much enjoyment with them in the future!" Speakers used with the AUVAs: Piego Coax 511.”

“Devices like the AUVA are few and far between. Relatively inexpensive and noticeably effective.”

“only when we remove the Stack Audio from the system we really realize how good they are”

“The Auvas sound better, while still doing the Gaia trick of keeping vibration in the air”

“More controlled and clearly contoured bass resulting in noticeable improvements in attack.”

“I have noticed a reduction in the bloom in the mid bass frequencies, which is an annoying characteristic of these speakers, and greater focus in the mid-range and upper frequencies.”

“the bass is the biggest beneficiary, with it being far tighter than ever before. There is also a much more open sound across the mids and highs.”

“The 100s cleaned up the bass further and provided more definition and clarity, it's amazing how much more detail is in the bass now!”

“my perception would highlight two aspects: better "clarity" and more "spatiality" or "three-dimensionality".”

“As soon as I installed the 100 I noticed a huge improvement. Bass is now tighter and more controlled and as a bonus I could hear everything more spatially open.”

“The imaging is much more focused than before, with better separation between instruments.”

“All I can say is WOW!!!! I don't know where to start. Everything seems to have tightened up. More bass control. The midrange is way more forward and present. The spacial separation is insane.”

“Saturday morning I installed the AUVA's and right away I heard the difference. A much tighter bass and cleaner mids and highs.”

“WOW, I've never heard it sound like this before. Fuller, richer and extremely detailed.”

“The 50’s are fabulous, the 70’s are sensational, the resulting clarity of my speakers output is incredible.”

“The combination now sounds absolutely spectacular with top to bottom significant clarity and soundstage improvements”

“the verses in singers songs that I could not make out before with some recordings are now clearer to pick up which is great.”

“The bass is tighter and better controlled, the midrange more open and natural, and the soundstage has improved noticeably”

“the 50's work quite well in helping "clean up" the overall sound stage and clarity. I really couldn't be happier.”

“Found immediate improvement with the Bass performance and soundstage seemed somewhat deeper”

“It make the V2 sound a lot better along with a lot wider and deeper sound stage.”

“Certainly the bass seems to have more depth and control (to quite a surprising extent), while I'm also hearing a bigger soundstage and more fine detail (reverb, decay) etc. than before.”
