“I ordered the AUVAs for my ProAc D48R’s. I wanted to know if spikes could be surpassed. The concept sounded promising. This time, too, my expectations 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!”

“Just installed the AUVA 100’s under the LINN. Really sounds good with them. I guess Linn already has spring suspension and the AUVA is holding them firmly and absorbing any vibrations to and from the turntable!”

“The set up was simple and the new sound spectacular. I have looked for this product for 40 years and never found anything I liked. You have come up with a great product that will work well with any system. Congratulations. Hope to stay in touch. The Avalon‘s are great speakers, but the isolators take them to another level.”

Stephen D. - USA
“The AUVA Isolators are not designed artwork but they sure as hell work!  My impression….. The hunt is over!  I’m now satisfied that my system is performing as intended. The enhanced clarity allows for higher volume listening levels and increased listening experience. Thank you.”
Pedro N. - Portugal

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