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

Read the link quoted above.  I don’t pretend to understand all of the amp’s measurements, but I know from speaker building that some that measure well don’t sound particularly good, and vice versa.  My speakers have a good 5dB peak from 10 kHz to 20 kHz; they don’t measure flat.  But that steadily increasing response has a lot to do with the air and detail I hear in the treble section.  I could control for that peak, by filtering it out and up with a dull and lifeless response that measures flat. With the STA-200, I’m letting my ears be the judge, and apparently others are doing the same.
The test was done into a 4 ohm load. Rated output was measured as 76wpc. Seems to me one might consider this amp as a 40wpc at 8ohm supplier. Did I miss something?
I tend to not put much stock in reviews when people take a fantastically reviewed piece of equipment, and say, "but look at these measurements I came up with"..... Especially when it is a lone voice.
