I am a member of several that have been mentioned but only post over on AudioKarma. The traffic over there is quite a bit heavier and I have got some great deals on speakers from 2 members. I have become a fan of older DCM speakers and there is a fairly good following over there for those speakers.

Having said that I guess because of the smaller size here I have come to better know the perspective's of many more members here and it helps me when (if) I get answers to my noob questions.
