with the 4 Pi Pro's, effortless power and dynamics. Un-rack mounted, ie sitting on a shelf, it's dead quiet with your ear to the woofer, a slight sshhh from the tweets. Not sure how common the problem is, but mine had lost "bass extension" on just one channel. Replaced the electrolytic cap in the feedback loops, and the problem was solved. Thomas, if you own a DMM, be sure to verify the output device bias settings, adcom bias pots are really inadequate, now that I've had her opened up, I'm ordering "multi-turn" replacement units soon.
