If your speakers are moderately efficient (ie: 89db or above), i'd look at the Nakamichi Pa-5 Stasis amp on the 'Gon. The guy is asking $349.00. These amps were designed in consultation with Nelson Pass & have quite a following. My only caution would be this seller doesn't have any AG feedback, so i'd be enquiring if he has any Ebay feedback and sticking to Paypal. I would think it would be hard to find a better amp at this price point ~ http://app.audiogon.com/listings/solid-state-nakamichi-pa-5-stasis-stereo-power-amp-2012-11-16-amplifiers-22601-winchester-va
With that said, if you could up your budget, there was a Threshold S-300 on the 'Gon for $800 a few months ago which would kick the Pa-5's butt! ~
