Marantz or Emotiva as processor?

I'm plotting my home theater and audio makeover and could really use some advice.

First, room is 15x20.
Second, planning to get some quad 22L2 for the fronts.
Second, I care about 2 channel fidelity above all, but getting a solid ht processor is important too.

Remaining speakers will be junk onkyo htib until later.

The question is, do I go with the marantz sr6004 refurbished for $600 or the marantz sr7002 refurbished for $600 or the emotiva umc-1 for $700.

I've heard marantz and like the sound over denon and pioneer.

I'm not sure what will power my speakers yet. Assume emotiva amps, but I'm open to suggestions. My total budget for pre/pro/amp is $2000.
