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

Check pictures of the Job 225 and STA200 again. They use the same circuit board with different caps, resistors, etc. The power transformers and RCA jacks are also different.
I guess adding to the above, and I have not looked into it at all, I get the impression that the STA200 is the only non class D amp they make?
I am not concerned one way or the other, but based on the above and the link, do you believe that the Nuforce and Job are more or less similar amplifiers?
It is well documented that the STA200 is a scaled down version of the Job 225, which is based on a Goldmund reference design.
