Sometimes, maybe once a day, or every other day my normally fine sounding Icon starts pushing about 10% high frequency hash thru it's outputs. I don't think this is the 'I have high efficiency speakers and I hear a little noise' problem. It's a 'this sound is unlistenable, but if I turn the unit off and on it goes away' problem.
I really like the sound of this unit, it's handily the best of the little amps I've tried. But I'm really wondering about this 'need to reset the unit'. Wait a minute, Microsoft didn't do part of this design on this did they?
