Hifimaniac- That's not true about the sistrum stands(as I understand there "theory") they do not isolate perfectly, in fact they do not isolate at all. They couple, or so they claim that's how they work. My intention is not to have this become yet another Sitrum vs. thw world thread, I have heard them used in friends systems, but didn't hear much for improvements. I have some SP-1's a friend is going to let me borrow locally for my system- then I will get to try first hand. But for some reason I really doubt "coupling" is going to beat a sub-heartz platform.
