Parasound HCA1500A - 19" Rack Mount

I just purchased another Parasound HCA1500A, from the same guy, he has another available. $550/obo + shipping. It is a John Curl design, amplifier pioneer, and designer of Mobile Fidelity Sound Labs(MFSL) recording facility(Original). I wasn't sure if any of you are interested but here are some specs from the website:

It is a really great amplifier. We demo'd my first one on F1's SDA's and it had a noticeable increase in bass, clear mids, clear highs. I have read comments that the amp is heavy in the bass area, one commented that it was a little "dark", but I have no idea what he meant. The amp was more than ready to keep on going, it has some very large guts. We just did normal listening... F1 had more time with it than I did. He may offer some comments.

We are planning on using both of them, bridged to 630wpc, on his SDA's this Friday or weekend...unsure, but it looks to be pretty cool experience.

Drop me a line if you have any seller or Parasound questions.

Thanks for looking.
