@karl_desch ,
I know Mr. V. believes his speakers sound better on a granite block.
I have my Treo's on maple butcherblock at the moment.
I was going to try Townshend Podiums, but the outrigger feet made that unusable due to my limited floor space. (They went under my preamps- and made a noticeable positive difference).
In any case, I think the Gaia provide much the same 'uncoupling' as the Townshend Podiums. And, I think your observations to be much the same as my experience using the Townshend Podiums under my preamps.- A cleaner, more defined sound, with the bass tamed but not muted.
Overall, better.
