The single most important component in ANY audio system, regardless of the channel count, is the ROOM. A room with a glaring sonic flaw will not be correctd with electronics or speakers. You can't generate a 20Hz note in a 10x15 room regardless of how badly you want to or what the salesman who sold you that subwoofer said. Your audio system's sonic profile has to be tailored to the room or you're just throwing away money and fooling yourself. That said, to the OP... Try the Denon. The sonic characteristics of Denon electronics work and play very well with the sonic characteristics of B&W speakers... especially the modestly priced B&Ws like your 602s.
