I have the 3806, but I don't have B&W speakers (I have DefTech BP2000 mains / CLR3000 Center / BPVX surrounds). I would also wait and see how the 3806 sounds with your system. For mine, I would like to add a separate mono amp for my center or something to take a little bit of the work off the Denon, but that's not a big priority since for 99% of my listening, the Denon handles everything great. It's only when I want to turn things up pretty LOUD that another amp would be nice. Just wait and see how the Denon does with your system. It's a nice receiver, not a true 120x7 all channels driven... but it'd eat a Sony receiver up any day!
