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?
Stack Audio Auva Isolator
I just ordered a set of these. They are supposed to be better than the Iso-Acoustics or even the Townshend podiums for speakers.
Anyone try these yet?
