Hello, all. I will soon replace my Sony V555ES with something that offers a more stable amplifier section. I've narrowed the field to the following candidates: Denon 3803 Denon 4802/R B&K AVR-307 (a $2,675 display model that lacks the processing of the first two, but dang it's a killer piece!) My primary concerns are build quality, sound quality (duh), electronic stability, and future-proofing. I will be using the unit in a 5.1 setup, as my HT room is on the small side. A sneaking suspicion is that the B&K is probably the best-built of the trio (best warranty, too), but I'm doubtful that it's worth a $700 premium over the 4802/R -- I'd really like to stay as close to the $2,000 mark as possible. I tend to be be a moderately critical listener, but lack the resources to make the jump to separates. Although I realize most receivers have limitations, the value of "one-box" solutions cannot be ignored. Any advice or suggestion of worthy alternatives will be sincerely appreciated. Happy listening!
