Well.... I don't want to bore everyone with my tale of woe (as my previous Marantz amp had a different, but equally irritating fault). But my current problem is this:- Every time I try to watch a film with 5.1 sound (on Marantz SR4300), I'm constantly distracted by a crackly noise emmiting from the left-rear speaker. The speaker is still outputting the usual surround sound, it's just that it's always accompanied by a faint static-like noise. I tried changing the coaxial lead from the DVD player, and tried a different player altogether, but it didn't make any difference. I even tried swapping the rear speakers around, but the crackle is still present (and still left-rear, despite the swap). So I can only assume that the amp itself is to blame... Any ideas what may be up with it? (some sort of magical quick-fix that hadn't occured to me would be ideal!). I've had it for about a year, but the problem has only been noticeable for the last month or so.
