Thanks for replies...I took a look at that Sumo, Timlub. Interesting unit. I'm kind of married to Parasound or Adcom at this point...I've spent so much internets time reconning those two to the bone. This amp is really to hold me over until I can get one of my wish list amps, used, in the $700-$1000 range. I've been using an Adcom GFA-545 until now, so I'm also sort of interested in hearing a Para. There's a Parasound Halo 23 on ebay for $500, and I'm really conflicted about it. That's almost "keeper" quality, and it's at the upper end of what I want for now.
As for the 1200 II, it doesn't seem to have been "professionally" reviewed, but what little people say about it is positive, more or less. It sure looks like an HCA-1500A on paper. I would love to find a 1500A for less than that Halo, but for now, I'm kind of resigning myself to getting a GFA-555 (which is not a bad amp) for $300 or so.
btw here's some info on the Sumo Andromeda II and original, in case anyone's interested:
