Want to upgrade from Emotiva UMC-200 and/or Outlaw Audio 7500?

I want something used under $800 or so per unit. Don't care about features other than having HDMI inputs on the pre/pro. Seeking the best sound quality. I have Magneplanar speakers with a 10 inch powered subwoofer, and an Oppo BDP 95 in a small room (13"X14" and can't play it too loud). I listen to classical, jazz, classic rock, new age (in that order). System used 75% for home theater and 25% for music.
