OSD Nero HTA4200 in mint condition. 140w x 4 or 400w x 2 bridged. Very clean detailed sound with plentyof headroom. This amp is built very well and performs far better than an amp at this price point should. I've had Emotiva and Outlaw Audio amps in the past. This sounds better than both! It's runs cool and quiet. I've loved it but upgraded to an amp with more channels. Comes with the box, power cord and manuals. It still has 4 years of warranty left. Check out reviews on YouTube. Auditions available.
