NHT Power5 ** Price Reduced **
5 x 200 watts per channel. Fantastic home theater amp - very powerful but compact and runs cool. Class D amp, using Bang & Olufsen's "ice power" amp modules that have had very positive reviews. NHT brought out this amp with a few other pieces of electronics in 2007 but even though the reviews were great, decided to focus on their main business of speakers.
Retail was $2000, this was purchased in 2008 and I have the original box & manual. I was using this as a spare, have an identical one in use (and keeping - these are great amps). Very conservatively rated as 8/10 condition, only noticeable cosmetic flaws are a couple of light scratches on top of case but otherwise pristine.
Dimensions: 5.75" H x 17" W x 17.25" D, Weight = 37 lbs
