AUVA Equipment Isolator

The AUVA Equipment Isolator synergizes two distinct vibration-absorbing technologies: AUVA and CSA, working together in perfect tandem to achieve unparalleled Isolation performance. The rigid machined aluminium shell of the AUVA EQ is designed to sit underneath the piece of Hi-Fi equipment in direct contact with the case. The silicone absorber sits on the hi-fi shelf or rack. As such, the case of the Hi-Fi equipment is directly coupled with the AUVA chamber of the EQ but de-couple from the Hi-Fi shelf via the CSA suspension.

The Custom Silicone Absorber is specifically formulated to absorb high levels of external vibration including room reflections and reverberation that can be transmitted up through HiFi racks. The CSA is height adjustable and comes in 3 versions to work optimally with different weights of equipment:

Optimal load (per foot)

CSA 1: 0-4kg, (0-9lbs)
CSA 2: 4-10kg (9-22lbs)
CSA 3: 10-15kg (22-33lbs)

All weights are per isolator, divide the weight of your HiFi by the number of isolators you will be using to ascertain which CSA insert you will require. For example, a 15kg amp using 3 Isolators would be 15/3 = 5kg (CSA 2).

All AUVA products come with a 30-day money-back guarantee.

“Thanks for getting these to me so quickly. They are truly worth it. There is less smearing, more definition, tighter bass and better spatial queues. I’m sure that has all been said before based on seeing others’ reviews of these.”

Henk R. - Germany

“I hereby tell you that the SQ effect is even more profound than I expected. Depth, tightness of the lows, air etc. All the clichés you often read are more than applicable now.”

Havard D. - Norway

“Immediately I noticed more separation, or focus, as Chesky Records say. Individual instruments were easier to hear, but also background vocalists. Especially the live version of Money which has a crowded soundstage with many instruments, but also the synthesizer ‘floated’ better in many songs.”

Martin T. - USA

“It’s not difficult to speak highly of the AUVAs, as they are remarkable as a musical upgrade. To say I’m thrilled with them is an understatement!”

Marcel B. - Netherlands

“I have tried the footers under my vintage Philips CD960 player and it gave a very clear improvement in the depth and layering of the sound. Great product! Thanks again.”

Ted S. - USA

“When I look back at some of those games on Youtube I think to myself that what I am seeing on Youtube is nothing like what I remember from when I played the game all those years ago. I remember the game being so much more vivid and real than the pixelated image I am seeing on Youtube.

I believe what is happening is the effect or power of the mind to fill in the gaps of the pixelated image and reality. Our minds are that powerful. But that takes energy and work in the mind. Something that I had much more reserves of when I was much younger. As I aged I noticed that expending that same energy today tires me more than it used to.

Listening to my system at night, critically or with intent, has led to some nights in me becoming tired after a while of listening. Some nights are worse than others. I believe, in my case, some of the cause is my mind working to fill in the gaps of the music my system is producing with that of how I hear things in nature or around me. My mind is working to decipher what instrument is being played or what that artist’s voice sounds like.

After I installed the EQs under my DAC the magic and effect was immediate and undeniable. All the descriptors that Hans Beekhuyzen used are there. But what I personally found different was a relaxing of my brain. I was listening to the music instead of analyzing the music. I believe my mind didn’t have to work as hard to add in the transients and multi-layering of the human voices and instruments being played. The plucking of a string had all the extra details that the brain knows are there in reality but I wasn’t hearing in my recordings on my system as easily.

This effect is much like the improved graphics of computer games and the use of shading and reflections in games. You see the beauty in the newer games but the other effect is your mind doesn’t have to work to fill in the blanks between what you are seeing on screen and reality. You can then spend more energy immersed and enjoying what you are seeing or hearing.

I feel that is the effect I am experiencing with the EQs. Everyone is different and everyone’s brains work somewhat differently. I have a friend who honestly can’t tell the difference between a basic MP3 and a high-resolution file.

I look very much forward to ordering more of your devices in the future!!!”

“The EQs combine well with my other isolators because each type has different tuning and strengths. The AUVA EQs sound best on my preamp in my current system, and it’s an improvement in the overall system frequency response.”

John P. - USA

“I received the EQ’s and have put them under my turntable. Wow, just an immediate improvement to the music. Much cleaner and less noise. Really amazing!”

Ron W. - USA

“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…”

Klaus B: - Germany

“Our experiments brought us to the following conclusions: Using the EQs with source units (Oppo and TT) Resulted in improvements which were clearly audible and essential. it sounded as if the musicians were present in the room!”

Ron T. - Germany

“To apply the EQ’s directly under the casing of my preamp, I dismounted the original feet, as these almost have the same height as the EQ’s. This makes it more challenging to also try them out under the power amp, however, I do not think I will need to do so at this stage. The results are really surprising, again I am hearing a quite significant positive change! The bass seems extended and has (much) more texture and detail. The reduced level of (micro)vibrations going to the preamp also contributes to more clarity in the mid and high range. It all results in an even more immersive listening experience, where I did not think that would be possible to such an extent by such a relatively simple solution, without moving to a higher level of equipment. It only shows how (the avoidance of) vibrations really impact the sound quality.

All in all, a very positive result so far, I spent quite some hours listening to all sorts of music, which always is the best indication that something changed the sound in a positive way!”
