I have the 6371's and I absolutley love them.
From a build quality standpoint, Ive yet to see a speaker that can better them. They are beyond beautiful.
The sound is warm and clear. Bass is a little light, Ive heard the 81's are much better. Light though it may be, it is still crisp and precise.
These are keepers in my book, especially considering the price break.
North American and Euro Hi-Fi manufacturers better take heed, The Chinese market is coming on hard.
