“Over the past two years, I have owned a variety of isolation/coupling devices to include Stillpoints, Symposium Rollerblocks, IsoAcouctics component and Gaia Speaker Isolations devices. They all made some positive improvements but they all lacked the speed and the 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.”
