Nuforce STA200


I am curious about the Nuforce STA200 amplifier  If anyone has experience with the amp it would be appreciated if you would share your listening impressions, both good and bad.  Some of the descriptions I have read classify it as a class AB amp and others a class D amp.  I am not technical savvy about these things, can a single amplifier be both? 
Thanks

Very clear and warm. Good depth and dynamics. Did not use with speakers that had deep bass. I think the TAS review was quite accurate. I think Audio Advisor still has them new for $500
I saw that Audio Advisor only had 8 left. I just ordered one. As I update my main system with a much higher end amp and pre, I'll be building a system in out master bedroom. My Nova pre will make the move. However, wife says that my B&k st140 will not make the move. The Nuforce will blend in nicely. I'm sure it will do fine for what I need it for.
