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

TOO MUCH GAIN. Even with my McCormack passive preamp I can't turn my volume knob past the 10 o'clock position without leaving the room holding my ears.  There is no need for a preamp. All you need is a attenuator between your source and the amp. 
I have one driving my Klipsch Forte II speakers.  They are 8-ohm and have 99dB sensitivity.  It runs cool.  I WONDER if they could handle the 4 ohm JBL L-100 Classics? 
Just like Job amps, as long as your speakers don’t fall much below or preferably not lower than 3 ohms, you’ll be fine.
