0.2 multichannel preout, so does that mean just two subwoofer outputs? I'd have to jump up to the X3700H?
Yes ... only subs ...
Marketing figured out quite a few years ago that people who cared about pre-outs were willing to pay for it. So it's only offered on the higher end models. I could not find a 5.1 with pre-outs and had to go into the higher-mid tier of Marantz to get it. Think new it was suppose to be a $1000 USD. In the Denon line up, I believe, you have to get into even higher tiers than Marantz for pre-outs.
