PS audio hca 2 feedback...

Agree, with Kck and Richards. In my case, a particular asset is the HCA-2's indifference to the low impedance of my Maggie 1.6's. I use the HCA-2 with a tubed preamp with adjustable gain. The pre sounds best set to it's lowest gain, so the rather high gain of the HCA-2 is a benefit in this scenario. I had been rather frustrated with the 1.6's until I tried the HCA-2. It has proven to be an excellent performer, especially for the price. I did have some problems at first that required a trip back to the manufacturer and I have received excelllent, fast service/support.

I would say the differences in my system were well worth $800. Of course, the better the rest of your system resolves, the more you will hear the differences. With that caveat, I'd say that all of the problems that 10Audio.com groused about in their review of the HCA-2 are dispatched. The amplifier is much more refined now. It's hard to quantify percentage of differences in change, we each attach more importance to various performance parameters. I'd have a hard time going back to a stock version now. Rather than decoupling the transformer, I fabricated a non-magnetic copper and stainless retainer system. It is too easy for the heavy transformer to slide around when pulling the amp in & our of my rack.
