I'm looking to upgrade my old H/K AVR 30. I'm hoping to stick under or around the $1100 area so I can still get a SVS sub. I see lots of praise for Denon 3803 and H/K in general. But I have seen several threads of people having problems with H/K 7200 and 8000 with some speaker buzzing issues. I'll be using the receiver for music and Home theater. I'd like to stick with 6.1 capability, I just put in 3 rear paradigm reference series ceiling speakers to complement (I hope?) 3 front B&W 805 matrix speakers. I'm thinking I can use my old AVR 30 to power/listen to speakers in the kitchen and another set in another room. I guess I just send audio out from the "new" receiver to the "old" AVR 30 and then I can use the "A" and "B" speakers of the old AVR30 if I want those speakers on or off??? I only mention this because I guess I don't need the new receiver to have Multi-zone capability if I go this route. So any suggestions on whether to get H/K AVR525, H/K AVR7200, H/K AVR8000, or Denon 3803, or maybe another I'm overlooking?
