Parasound HCA-1000 High Current Power Amplifier. Total harmonic distortion: 0.03%. Signal to noise ratio: 110dB. Power output: 125 watts per channel into 8Ω (stereo), 400W into 8Ω (mono).
Glad I decided to pay a bit more and get one that had updated caps and resistors. No need to worry about it going out of spec due to age of components. Sounds like a new unit. I need a high current amp to drive Magnepan speakers, and this should do a fine job.
