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

brad, if you were to connect the Nuforce to your speakers, without connecting anything to the amps input, ( any amp for that matter ), you may find the Nuforce / other amps to be quiet through the speakers. I have done that with both of my Nuforce amps through my 104 db efficient speakers. The Nuforce amps were silent.I believe you may have a problem with the Freya, or a tube ( s ), as others have not reported very loud hum / static / hiss etc. Enjoy ! MrD.

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.
