I use an NR1200 in the living room with just 2 speakers. It's overpriced for what it does, but I bought mine a couple years ago when they were still pretty cheap. I had a Yamaha 5.1 but got annoyed because it would keep putting itself back into multichannel mode at random times when I had set it for 2 channel. Annoying as hell when it sends your dialogue to a center speaker that isn't there. I no longer have those problems.
The Marantz' biggest flaw is lack of bass management, so you'll have to cross over your sub pretty low, like at your speakers' F3 so you wont get a lot of overlap in bass frequencies.
There is a little bass adjustments the user can make, but nothing like the other units. This might be perfect for my daughter,
Well the NR1200 does have a bass adjustment knob on the front panel along with a treble adjustment knob. Hence the old 'Tone Control" .
Plus one can adjust another way:
