Stack Audio is a UK based company pioneering in vibration management, streaming products and ethernet isolation.
This post concerns their various acoustic isolators, which fall under the rubric of AUVA or Audio Vibration Absorption, of which they say:
This technology… “harnesses the power of Particle Impact Dampening which eliminates vibrations across a broad frequency range, unveiling remarkable clarity in musical recording. The vibrations excite the particles, creating movement and collisions that dissipate the energy virtually instantaneously. Think of it like throwing a ball into soft sand -the sand absorbs the energy from the ball, preventing it bouncing.”
Today my audiobuddy Marc (who is also becoming a good buddy in general), came over to do some listening.
He knows my system and room very well, and today he was quite impressed by the sonic impact of the Stack Audio AUVA Isolators under my electronics (versus the prior Isocaoustics Oreas), and the Stack AUVA 70s under my speakers (versus the prior Herbies Titanium Speaker Gliders).
Marc and I agreed that the Stack Audio Isolators were clearly superior across the board, particularly in terms of presenting an exceptional level of clarity and naturalness, improved soundstage-width and -depth (in this regard, perhaps most notably in the far rear corners of the stage), the organization and air surrounding individual players on that stage, dynamics macro and micro, bass extension and impact that you can feel in your chest, together with a sense of absolute quiet–yet without a hint of darkness–rendering instrumental decays that seem to go on forever, at least until clearly truncated by the mix.
One caution that one might not think to extend to isolators: it takes some time for the magic powder in each isolator to settle–not so much a break-in process, but a settle-in process which can be hastened a bit by a horizontal shake and a few taps on a horizontal surface.
Happy boy!
). My best audio bud is coming over on Monday so we can both make a final assessment, or tweaking, as the case may be*. Once that’s done, the SDFB is next. I’m going right to the graphene with that one!
