Stack Audio Auva Isolator

@ozzy - I agree with Wig, no settlement time

I have Stack Audio Auva 70 under my Sound Anchors stands, with ATC SCM19v2 speakers.

Have a set of Auva 50 to put under my audio rack this weekend.

And Auva EQ under a Puritan PSM156.

Here is what Stack Audio replied to my question.

"The AUVA Loudspeaker Isolators have a burn in time to let the particles settle. We estimate around 6-7 hours although customers have noted continuous improvement up to the 20-hour mark in the past."

"Just a follow up note – I should also mention that several customers comment that no burn in time is required and there is an immediate impact. I think it varies on a case-to-case basis.

Personally, I noticed improvement immediately. As time went on, my system got a little better - smoother mostly and better soundstage and clarity as well. But improvement was immediate. 

I will be interested in your experience--my understanding is that AUVA w/ spikes will couple (not isolate) the speakers to your concrete floor while your podiums were de-coupling your speakers from the floor--one would think the results would be vastly different but since you're using different speakers than with the podiums i wonder if a true A/B is even possible?  Maybe try them with and without the spikes?
