I currently have a Denon AC-3 ready 2600 but it has developed some background noise (?cause) so I am looking to replace it with a less expensive receiver that has decoders. I have narrowed my choices down to the Denon 1802 and HK 220...any opinons? I will be using it 70% for TV/DVD and 30% for music. It will be driving Klipsch 5.5's with 1.5 surrounds and a 10" sub. Thanks!
