Thank you to Bryan L for submitting his feedback on the AUVA 50 Loudspeaker Isolators.

"After installation, I was taken aback by the level of change, which I would categorise as transformational. The bass greatly improved, and I can hear the drumbeats reproduced with greater snap. The vocals are more separated from the instruments, more prominent, more centred, with greater tonality/texture. The soundstage widened, and I can place the instruments more clearly.

I can now say I believe the improvements mentioned by the many reviewers. I was initially torn between ordering this or the Isoacoustics, and I definitely think I made the right choice."

Thank you, Marc, from Sound Matters, for reviewing the SERENE Record Mat.

"What the SERENE does really well is control. On the Buckingham Nicks album, the presentation felt clean and stable without becoming clinical or thin; it gave the music a composed, well-organised feel."

The SERENE Mat is covered by a comprehensive 60-day money-back guarantee. If you feel it doesn't significantly enhance your system, we will arrange collection and process a full refund.

Over the years, I’ve used and tested quite a few platter mats, from...

Volker Frech put the AUVA 70s to the test in his recent review for Litemagazin.

"Thanks to greater accuracy, the music gains coherence and timing, increasing dynamic range and providing more freshness and vibrancy. Singers and instruments have greater presence and body. Furthermore, the 3D representation is more immersive. The increased spatiality is accompanied by greater openness and airiness.

Thus, the AUVA 70 offers a significant performance boost and, considering the sonic improvement, is truly excellent value. Highly recommended!”

Thank you to HiFi.nl for their fantastic review of the AUVA Platform, which received a 5/5 rating.

"Wherever I deployed the AUVA, the reproduction consistently improved. In the silence in the background. In the tranquillity imparted to the system. Especially in the stereo image, which gained depth and height, and could just as easily become wider. Also in naturalness, detail, and spatiality, in which, for example, reverb was given the time to slowly fade into the background. Voices lost a ragged edge, even if that wasn't really noticeable before; instruments detached more from the harmonic overtones they produce.

In all cases, I was delighted with this upgrade in my systems, right up to an experience with a tube-based power amplifier where my jaw dropped in pure amazement. Stack Audio is doing something fundamentally right with its AUVA products, time and again, as I have come to experience over time."

Thank you to Radoslav from Slovakia for sharing his feedback and pictures after adding AUVAs throughout his system over the past two years- a seriously impressive setup featuring Simaudio, Mola Mola and Vimberg.

"Maybe the biggest change out of all EQs under my electronics so far. Everything is more gentle, and the background is even quieter. Space is wider and more real."

That was after installing AUVA EQs under his Simaudio Moon 791 streamer/preamp. It wasn't the first time he'd noticed the difference either.

"Deeper soundstage, better localisation, and also better dynamics."

And on his Mola Mola Tambaqui DAC:

"Helps Tambaqui to really shine."

The AUVA 70s under his Vimberg Amea speakers have been just as consistent.

"The AUVA 70s on my speaker stands are doing a wonderful job"

He now runs Stack Audio isolators across his entire system.

Thank you to Lip W. for sharing his feedback on the AUVA 100s.

The Kharma DB9s sit at the top of the tree, driven here by a Lamm preamp and Gryphon Essence power amp on a full Finite Elemente rack. Every system has vibration to deal with. Even this one.

"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."

Thank you to Jee P for sharing his feedback on the AUVAs and a picture of his stunning system.

"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.

These are five-star products, and I’ll be reaching out later this year for auva for my racks as well. Attached is a picture of my setup. ✌️"

"How do AUVAs compare to the Gaias?" We get asked this a lot. Here's what owners who've used both say.

"I'd been using Gaia IIs, which did a good job, so I wasn't expecting miracles. Must admit though, the AUVAs make a night-and-day difference. I mean that literally."

Fifteen owners told us what happened when they replaced IsoAcoustics Gaia feet with our AUVA isolators. Under Harbeth, Magico, PMC, ATC, Kharma and more.

Thank you to John R for providing his feedback after adding the SERENE Mat to his Rega P10.

"I was so impressed at the difference the mat made that it hasn’t been off my turntable since it first went on!"

Should you isolate your HiFi rack?

Speaker isolation deals with the most energetic vibration source in the room. But every component on your rack is connected to the same floor through the rack's legs, and a rack on spikes gives vibration a direct path up into everything on every shelf.

A rack still needs a rigid, stable connection; a spike provides that, but nothing inside it absorbs anything. The AUVA Loudspeaker Isolators keep the rack fixed while particle-impact damping dissipates vibration before it passes through. One reviewer fitted six beneath an already heavily engineered rack and reported a clear, repeatable change he didn't expect.
