Thank you very much for the help/advice. I'll do the RCA to RCA routine. So far, the amp is great. It runs my B&W N804's/ HTM 1, & others like a champ. Question - Does an amp like this require a "break-in" period of time? Seems like it sounded a little smoother after about an hour total time. Possibly just my imagination. Anyway, I'm going to leave it on continuosly for 2-3 days, on principle. Again, thanks for the help.
