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

Even the Job 225 on which this amp is based does not like speakers that dip below 4 ohms. The problem is the speaker not the amp. Elac recommends amps with 140 wpc and 4 ohm stable.  That is the problem with these "marvel" Elac speakers and before them the Pioneers that Andrew created.  The speakers themselves are cheap but the amplifier requirements are not.  
I run Salk SongTowers which are 4/6 ohms...can run all day without issue...have never found any ratings or measurements for STA200 except 8 ohms...
Thanks. I suspect it's the speakers. No problems with a Cambridge CXA 80 driving them but the Nuforce runs pretty hot. I also have it in a cabinet without enough ventilation and was really running it when it happened.  Going to add ventilation and swap in some 8ohm speakers and see how it runs.

The Elacs do sound really good, esp. since I got them on sale for $350.  Maybe I'll buy another amp and run two :)
The TA Premium PC came yesterday, quite an improvement over the less expensive  TA PC that preceded it.  I’m running AQ dbs Jaguar IC’s from my pre to the amp- I think that’s the next upgrade...
I have run my STA200 on several types of speakers, and it has had no problem running them to levels I am happy with. It runs slightly warm, and I leave it on 24 / 7, unless I am out of town overnight or longer. It has become my main amp for my Lascalas. Enjoy ! MrD.
