Here's another vote from a long time ecstatic owner of Parasound. I would however look online at Audiogon for a HCA-2200 mkII...make ABSOLUTELY sure it's the mk II version and you'll have a long time serious amp for about a third of what you quoted for the 2250...a little less wattage (220 vs 250), but a LOT more ampage (45 vs 90 peak per channel)
If you can't find one, then the 2250 is also excellent (although it is NOT a John Curl design) by all acounts that I have read
Good luck,
Konky.
