Speakers/Symposium Rollerblock JR's.

I use rollerblock juniors and svelte shelves under my floorstanding Acoustic Zen Adagios, on a suspended wooden floor. I was using Herbies big fat dots onto a thin sandstone block before. Both are a great improvement on spikes. I think the Symposium is a tad better, tighter sound with better defined base, but not a night and day improvement.

James The acoustic Zen site is'nt clear, but I feel you are correct, the Adagios are MDF. Coincidentally, my previous speakers were Living Voice Avatars. The Adagios are a very big step up in performance
