I consider myself an "advanced home user" and not a specialist or technical guru. From that perspective the Denon 3802 has worked fine.
A major consideration for this model was it's multi-room capability. As far as "weakness", well, I SIMULTANEOUSLY drive a Bose Acoustimass 15 system in my living room and a set of Bose 301’s in another part of the house. While I am sure there are more advanced or “power draining†scenarios out there…the Denon fits my needs well.
