Previous reviewers seem pretty uniform in saying that the detatchable power cord model outperforms the non-detatchable cord model. Luckily, mine has a detatchable cord. Thus far, I really like this amp. The Adcom is a bit more agressive and analytical, but not in a bad sense. There is detail without being bright.
Build quality is very good.
The binding posts could be more robust, but these are fine, particularly for the banana plugs that I use. Aesthetically, it looks like an Adcom. To the best of my knowledge, I haven't yet caused the amp to illuminate any of these lights. Apparently, many Adcom amps run hot, and mine is no exception. After playing a couple of CD's at moderate levels, the top of the amp is very hot to the touch, much hotter than my Rotel, Hsu, HK, or Yamaha.
