The Aragon amp is very good. It begins to approach the quality of better amps, but it will never be on par with the Krell or Levinson gear, unless it is being compared to integrated amps or HT gear.
I owned the 8008 for several years, and was very happy with it. I built a system around it, but when I replaced it, I bought a Krell FPB 200.
On paper these are very similar amps, both rated at 200 wpc into an 8 ohm load... the specs go on very similar, but the Aragon could not touch the Krell for impact and dynamics, or reserve power. The sound of the Krell was from top to bottom better than the Aragon.
That doesn't mean that the Aragon is a poor quality amp. It is not. It is very good, but know going into the deal that while it is good it has limitations that the comparable Krell or Levinson will not.
Aragon is relatively inexpensive, and a great bang for the buck unit, but not state-of-the-art.
