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

Well, I have been rotating amps in my collection, to determine which I should sell, and which to keep. I am still amazed, listening with the Nuforce STA 200 in my system. I cannot complain about it, tear it apart, want for anything. It does not have a house sound, and best, it gives an impression of the best of tubes and ss, in my system. Because I use a passive pre, it is extremely synergistic with the rest of my system, and simply works. It allows me to enjoy listening, which it is all about. It has been in my system for a month now, and I am doing fine. My best to all !. MrD.

I also have a STA-200. Don't use it often and when I do it is paired with a simple single input boxed attenuator due to it's having too much gain. Given it was discounted to $400 it can be classified as great return on investment when paired with a passive pre and a true 8ohm speakers (rated 80wpc into either 8 or 4 ohms).

Redundancy can be useful at times :-).
