Emotiva UMC-200 preprocessor. Home theater preamp. Possibly the best sounding preamp for home theater under $1000! I have compared this to a number of units, including a $2000+ Av7702mkii, and I'd venture to say that 19 out of 20 people couldn't hear the difference. AND here's the best part: it not only is in perfect condition, with box, etc.... it is still UNDER WARRANTY. DtsHD, Dolby HD, 7.1 this baby is fabulous. Shipping is $25 insured.
