Peter i have a question I turned my gain all the way to the left where before it was all the way clock wise on my JC2. My A21 was wide open to. So needless to say when listening to CD at 0900 on the JC2 volume knob it would scream but I turned my gain on my JC2 all the way off counter clock wise and my gain on my A21 to 1200. But now I have lost the ommph in the bass but the screaming is gone even at 1200 on the volume dial but does sound better. Is this one of these things of finding a balance and why did I lose bass on my proac d28's
