PSAudio HCA-2 2 Channel Amplifier Prelude Power Cable Everything is in excellent condition.

This amp is a winner, I have owned two, but ... after a couple of hours of listening the right channel began to misbehave with intermittent static. Not sure what this was about. I have a stand-by amp (Bel Canto Design) and I admit I am obsessed with balanced (XLR) components, so since that day the HCA-2 has been sitting. 150 WPC into 8, 225 into 4, fully balanced internal architecture, RCAs if you desire. Runs so cool, produces almost no heat. Has a few tiny marks on top, but face and rear are quite clean and look great. Some scratches on bottom. MSRP when new was $1695, current listing price reflects right channel issue. 17x4.5x14, 35 pounds. Owners Manual and original box/packing. Ships to the CONUS ONLY via USPS or FedEx Ground.

PS Audio HCA-2 Amplifier For sale, we have a PS Audio HCA-2 Hybrid Class A Stereo Amplifier in perfect working order. The amp has been serviced, including replacing defective output transistors, and setting the DC offset. The amp was then put on our bench where it went through our amplifier testing process. A 1k sine wave was run into the amp, while monitoring the output on our scope via a sine wave for signs of distortion or noise. Once we established there were no issues, we then slowly ran the amp up to full rated power using a dummy load provided by our Sencore PA81 power amplifier analyzer. The amp performed as it should and ran clean at 150 watts per channel at 8 ohms. Finally, we ran the amp in one of our house systems for several days where it performed beautifully. Physically the unit is in very good to excellent condition, with only minor blemishes, no dents, and no deep scratches. See pictures for further details on its physical condition. Included in the sale are the amp, original owners manual, display light adjustment tool, a generic AC cord, and original box with packing. More from PS Audio: Congratulations!

I bought this from the estate of an audiophile. This PS Audio HCA-2 stereo power amplifier is in great condition and it sounds great. I let it run for 2 hours while I enjoyed it and it didnt even get warm. When I moved it and tilted on its side I could hear something heavy move inside, so I took the cover off and a very large coil inside the unit is not firmly affixed to the case (see photo). When I ship it I will unplug the coil and wrap it separately so it doesnt get damaged. Here is a 2003 review from Gary Krakow NBC News: PS Audio’s HCA-2: You may have read about this in some of the hi-fi specialty magazines. It is light in weight (35 pounds), but the unique, heavy-duty circuitry produces 150 beautiful sounding watts per channel and it never, ever breaks a sweat. It always remains cool to the touch on the outside. This is one of the most neutral sounding amps that I’ve ever auditioned; it produces bass that has to be heard to be believed. Worth every penny of its $1,695 asking price. For shipping information, click on the shipping tab on the listing page and fill in your information.

When I moved it and tilted on its side I could hear something heavy move inside, so I took the cover off and a very large coil inside the unit is not firmly affixed to the case (see photo). When I ship it I will unplug the coil and wrap it separately so it doesnt get damaged. Here is a 2003 review from Gary Krakow NBC News: PS Audio’s HCA-2: You may have read about this in some of the hi-fi specialty magazines. It is light in weight (35 pounds), but the unique, heavy-duty circuitry produces 150 beautiful sounding watts per channel and it never, ever breaks a sweat. It always remains cool to the touch on the outside. This is one of the most neutral sounding amps that I’ve ever auditioned; it produces bass that has to be heard to be believed. Worth every penny of its $1,695 asking price. For shipping information, click on the shipping tab on the listing page and fill in your information.

### The Audio Board: www.theAudioBoard.com - The Search Tool for Used High-End Audio Equipment### I sold and shipped the amp to the buyer but he changed mind. The amp worked great; no issues. So, I am re-listing here. For sale is a high-performance PS Audio HCA-2 Hybrid Class A Stereo Power Amplifier It is in original box, with manual and heavy-duty power cord. I personally tested this amp, and found it worked great. Both channels produced good full music. This amp is built like a tank. Very reliable. The amp produces very musical yet solid music.
