I was wondering what everyone uses for a listening chair/sofa/beanbag/whatever? I ask because I've tried a few different chairs and they all had annoying resonances that would go off mightily at certain frequencies and be fairly distracting. Does anyone have a chair that doesn't resonate and annoy them when they crank their hifi to stupid levels? (I know I need to look into some sort of platform to decouple my speakers from the suspended wooden floor as that must be transmitting most of the vibes, but some of the frequencies are quite high and I suspect are just coming through the air. The sort of frequences that set off the foam padding...) Dunc
