Hi folks I got my new components yesterday (PW7, AVR-2805, DVD-2900) but I am having problems with a continuous buzzing sound through all of my speakers (all 5.1 of them) when everything is turned on. I have: Sky to Denon 2805 via JS Labs RGB>YUV Denon DVD-2900 to Denon AVR-2805 via component Denon AVR-2805 to PW7 via component Kef eggs and Kef sub connected direct to AVR-2805 The buzzing is constant but, by a process of elimination, I have found that it stops completely if I disconnect the sub audio connection. I have tested the sub on a friend's system and it functions perfectly so I am sure that its not at fault. Its all a bit weird and I don't have the expertise to work out what is wrong. Any ideas... Thanks.
