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? 
I purchased the STA200 a few months ago based on feedback from users of this forum. Speakers that I've used with the amp are PMC OB1 (6 ohm, 87db) and Alta Rhea (4 ohm, 87.5 db) and the amp barely gets warm with either.

For $500 it is a ridiculous value. I love the fact it doesn't turn into a space heater and doesn't take up a ton of space. At the price point, there probably aren't many amps that can compete with it.
Those are certainly some nice speakers, if it was "good enough" for those, I will probably be happy :)
The amp takes well to an upgraded power cord. Enjoy ! MrD.
Have one on order from Signal Cable. Reviewed very well for under $100 PC. 

I also picked up a Proceed BPA2 (on its way) I really miss the ML and I am hoping it will be a somewhat close match. Between the 2 amps, I am sure I will be happy :)
mrdecibel, what is the item that is on the stock STA200 power cord just below where the cord attaches to the amp?  I assume it doesn't impact ones choice of power cord? Thanks
