For sale is the highly regarded Hafler DH-220 Stereo Amplifier, known for its excellent sound quality. I have adjusted the DC offset voltage to meet the original specification, and tested it for THD at low power levels (I didnt have large enough loads to test it at full power), and it was at the low limit of my test equipment at 0.01%. Also I tested it with speakers...it sounds great! Here are the specs from the Hafler DH-220 manual: Power Rating: Less than 0.02% total harmonic distortion at any power level up to 115 watts continuous average power per channel into 8 ohms at any frequency between 20 Hz and 20 kHz with both channels driven.

Slew Rate: 10 kHz. 60 volts peak to peak square wave: 30 VI’,~ s. Semiconductor Complement: 26 transistors. 8 power Mosfets, 29 diodes, 4 zener diodes. 1 diode bridge.
