I think I should add at this point that I have no further noticeable hiss, so that folks aren't led to believe this is a problem inherent to the 1050. I do think a part of it was the older recordings of the Miles Davis CD. But it was clearly there on other CDs. I have been doing alot of general tweaking, added a Panamax surge supressor, made sure all my connections were clean, etc etc and am now very happy! (Except that the receiver no longer responds to my remote. But I have been promised a new one next week. Geez, I hope I'm not becoming a "problem customer.")
