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

I use that cord on my STA200 as well as Nuprime DAC-9 and CDT-8 and that combo sounds great   Salk SongTowers complete the system 
Did not do any comparisons, but sounded great with a Signal Cable PC. I'm sure a better PC will bring better performance. 

It opens up nicely with a superior power cord, especially over the stock cord. Enjoy ! MrD.
Hi, anyone have one of these amps shut down for overheating? Do they have thermal protection circuits? Mine cut out--was pretty hot. Let it cool down and it came back on. Driving Elac Uni-fi UB5 speakers--4 ohm. Very little info about these amps online. Are they okay with 4 ohm speakers?
Haven’t had any issues with mine playing 4-6 hrs at a time, actually gets only mildly warm, but I’m running 8 Ohm speakers.
