Nuforce STA200

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.

Even the Job 225 on which this amp is based does not like speakers that dip below 4 ohms. The problem is the speaker not the amp. Elac recommends amps with 140 wpc and 4 ohm stable.  That is the problem with these "marvel" Elac speakers and before them the Pioneers that Andrew created.  The speakers themselves are cheap but the amplifier requirements are not.  

I run Salk SongTowers which are 4/6 ohms...can run all day without issue...have never found any ratings or measurements for STA200 except 8 ohms...
