I really like the 1070 but I have front speakers that are kinda piggy (Energy Veritas 2.3s) and I really don't care about 7 channels, 5 is all I have room for in the bedroom.

I have a NAD 214 I could use to biamp the fronts (one channel from the receiver, one from the amp for each channel) but I would need to match the volume levels between the two using the preamp outs for the NAD. Anyone got any ideas?

P.S. I wish the two of the amp channels were reassignable like Denon, Pioneer, Marantz etc. have. But I really don't like the quality of the electronics or amps in any of those brands. Even better yet, preamp inputs to match the outputs would have been perfect.
