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.

David12, what are your speakers made out of? I suspect they are MDF based? MDF is not a good material to base a speaker or any audio component on. It is used as a low cost material that is very easy to work with and build boxes with, but the sound is not very good.

My previous speakers were Living Voice OBX-R2, and although they did sound good, they do have problems in the mid range. I believe these speakers are MDF based with a veneer finish. When I switched to the Wilson Duette (no MDF in the construction) I was really surprised at how much more detail and resolution I was hearing. I do not know to what extent, but I think avoiding MDF is a factor in good sound. That may be a limiting factor if your speakers are built with MDF.

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
