Following are its specs., as published in Stereophile
Rated output power, 20Hz–20kHz, with no more than 0.5% THD (FTC): 100Wpc
minimum continuous into 8 ohms (20dBW); 200Wpc minimum continuous into 4 ohms
(20dBW); 400Wpc continuous into 2 ohms (20dBW). Peak output voltage at rated
line voltage: 48V into 8 ohms. Frequency response: 20Hz–20kHz ±1dB. S/N ratio
(main output): <–80dB (ref. 1W). Input impedance: 100k ohms balanced, 50k
ohms single-ended. Voltage gain: 26.8dB. Input sensitivity (for 2.8V output):
130mV. Input sensitivity (for full output): 1.3V. Output impedance: !x0.05
ohms, 20Hz–20kHz. Damping factor: >800.\
I am the original owner and have been using it to drive JMlab Grande Utopias to great effect. It has no operational flaws, aside from my periodically having to hold down the power button for a few seconds to get it to turn fully off, (as opposed to putting it into standby mode). It has some cosmetic imperfections, mainly nicks on the bottoms of the heat sinks and smudges on the front, which are shown in the photos.
Reason for sale: am in a new house with (thankfully) a large listening room- bought higher output amp.
