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
George

MrD, thanks, the Nuforce was dead silent in the Freya's passive mode. 

Some early production Freyas had a lot of tube noise, but if I send it back I may just get a "that's normal" response and be wasting my time... 

I have decided for now to just keep using it in passive mode.

How does it run so cool? It is almost cold to the touch, even under load... Are we sure it is class AB?

Based on the same circuit board as the Job 225 so not Class D.

Brad, does it run cool on the speakers currently being driven with the Proceed ? It is AB for sure. As a correction, if I may. The STA 200 does not use the same circuit " board " as the Job, but it does share the same circuit design. The design is exclusively Goldmund. There is a lot of fascinating information about this circuit on the web, licensing agreements, and differences between the Job and the STA 200, and much more. Enjoy ! MrD.
