Stack Audio Auva Isolator

I see this thread is a little old, but I wanted to chime in with my experience with Stack footers.

It is funny because I observed almost the opposite of @lollipopguild , yet we came to the same conclusion that the Auva 70s are an improvement. Probably has much to do with systems and maybe even more so the floor that they are coupled to. I have a suspended hardwood floor, Dynaudio Stand 6 and Dynaudio Heritage Special speakers. My Isoacoustics Gaia iii's are more smooth, warm and relaxed and I always thought they were an improvement from spikes. In contrast, the Auva 70s seem to have a lot more energy and vividness. They also have more of that wall of sound feeling with well defined imaging. As was said above, both products are good and I could see some preferring the Gaia iii's in the right system. For me, I like what the Auva 70s do and I am keeping them. Definitely a very noticeable change in sound, probably more than the average component level change in my opinion.

Now, onto my experience with the Auva EQ component footers. I put 4 of these under my LTA microzotl preamp and the change was all positive. These replace Orea Graphite footers. The Auva EQs are more detailed with better clarity and imaging. I was really surprised by how much better they sound. I just ordered more for my digital front end. Excited to see what they can do there. I should probably try taking them out from under my preamp and trying them there, but the sound is so good I don't want to move them from the preamp. 

Wow. I am so impressed with the Auva’s! I put three under my Bricasti and one under my Sonore Opticalmodule and the sound got even cleaner and bigger. Maybe slightly less of an impact than they made under my preamp, but still noticeable. Cumulatively, this has been one of the best changes I have made to my system. I realize this is considered a “tweak”; however, I would consider this an essential product for my system now. Not terribly surprised that speaker isolation is important, but I wouldn’t have thought component isolation could make such an impact. 
 

I know I sound like super fan, but I am always excited to find “relatively inexpensive” and easy ways to improve my sound. My only other reference point is Isoacoustics Orea and Gaia so I can’t speak to how the Auva’s compare to the well regarded Revopods or Critical Mass footers.
