If you dont want to spring for a Symposium platform. I like a hard maple platform with cones under the component. Ive found it opens up the sound while enhancing detail.
Best isolation under a big receiver ?
I have found the gingko cloud to be great under my cd player, and am perfectly satisfied with it. But i have nothing under my big b&k avr307 receiver except the shelf it sits on. I know it is not as sensitive as my source, but i would still welcome your thoughts.
