Just began my listening to Buchardt 400 MK2. Initial impressions: substantially better than original. Now I'm running on an Anthem pre/pro and Emotiva power amps , which was not available for the original go around.
So, with that being said....wow these are really fine speakers. They sound sweet. The sound is clear, not tentative, no holding back, just a wonderful sound. Do yourself a favor...check these out!
