Hi all! First time poster, part-time (wannabe) audiophile. I have a set
of B&W 600 series 2 fronts -- left, right and center. They are
currently powered by a mid-range Denon receiver, but I would like to
upgrade to a straight-up power amp. Since the drivers in the speakers
are matched, I am assuming that I should keep the power as consistent
as possible -- i.e., a three-channel amp.

First, any comments on my reasoning there? Would you recommend just
going for a two-channel amp and running the center off of the Denon
receiver's amplification? I am primarily concerned with two-channel
stereo sound, but would like my video setup to be very good as well (I
am less concerned about the rears, however).

Second, assuming that a three-channel is the way to go, what
brand/model(s) would you recommend? I am somewhat familiar with the NAD
line and would be comfortable buying a NAD. The 906 (3 x 30 watts) and
the 916 (3 x 90 watts) are discontinued, but I think I could probably
find a used one for a decent price. My budget is $600 or less
(preferably something closer to $400).

Finally, I'm sure that the 916 would be preferable, but would the 906
work as well to drive the B&W's? Or would it be underpowered?

Thanks for all your help!
