Parasound A-23 or Parasound HCA 2200


What are the relative strengths of these amps, I see both available for a good price on ebay.  Thanks.

the original 2200 wasn't a John Curl, you need the 2200A for that...same with the HCA1000, the 1000A still is a great little amp. In the older ones they used the parts he specified, now they just use his circuit design, but cheaper parts...
it's actually the 2200II and the 1000A     The 2200 and 1000 were not John Curl, he redid the already existing models...
