I agree with WestCoastD, at least in theory the 785 should drive your B&W's more efficiently. I went with the 785 to drive my Monitor Audio GS60's because for the extra $400 I paid to jump up to the 785 I like knowing I have the top of the line AVR that NAD produces. Below are the differences between the 785 vs. 775.
Power output (stereo, 8 ohms within rated distortion 2 x 150W (21.8dbW) vs. 130W (21.1dbW)
IHF dynamic power 8 ohms 2 x 250W (23.9dBW) vs. 2 x 200W (23dBW)
Simultaneous power output surround mode 7 x 120W (20.8dBW) - [7 x 190W (22.8dbW)Minimum Continuous Power (FTC)] 7 x 100W (20dBW) - [7 x 165W (22.2dbW)Minimum Continuous Power (FTC)]
I know some of the numbers may not seem like much and some people would question just how much better is the sound between the two? All I can say is by buying the 785 you wont have to say to yourself "I wonder how much better the 785 would sound if I had it"
If you can hear the two on the same set of speakers that would be the best, but if not its just a bunch of specs that may or may not make a difference to you? Good luck in your choice. I am sure you will be happy with either AVR.
