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

sound is extremely similar...at the original list price, most found the Job a much better value, both for the extra power and the Goldmund name...so fortunately for us, the Nuforce was continued at this outrageously low price...
Thanks, jl352.  Incidentally, I was lucky to not have the preamp/speaker mismatch. I guess the three pairs of speakers I have used the amp with were not so efficient to create any (hiss/volume control)  problems.

I did end up purchasing the simple little Schitt sys which I like experimenting with just for fun, but most of the time I have it set full volume so as to not impact my tube preamp signal going to the amp.
Base on this thread,  I just purchased this amp from Audio Advisor. A Demo unit. I also have a Schiit SYS which I will try with it. Will likely pair it with a DAC/PRE in a second system later. Will get back after gaining some experience with this. Probably not work well this my Jolida Fusion preamp as it has 26dB gain.
