What the *#$@ happened??


I'll keep this short, just hoping someone can let me know what's going on. I changed out the platform my TT was on to a much denser wood, and I'm not really happy with the results. The good, I can hear more detail in the music, subtle nuances are more prevalent, better instrument separation, especially in complex arrangements. The bad, the whole stage moved back and got flatter, it lost depth. And the 3 dimensional characteristics of the singers voice also lost luster, became flatter as it were. It almost seems like I'm listening to a stereo now instead of a live performance. I thought the heavier wood would improve the sound, not degrade it. 
Anyone know why this happened?

Technically the Symposium is not a vibration isolation device. Isolation devices are technically not vibration absorbers either.

You could ask Clearaudio for the advice. As for tuning as opposed to just absorbing, I will be the first one to support this approach. After all I have Michael Green free resonance speakers. You can easily overwhelm them with very loud music, but within their operating range they sound very natural.
Still I am puzzled by the collapse of the soundstage depth that you experience.
Also, turntable is not a cd player, you cannot really extrapolate.
