The noise could certainly be coming from the PC, if it is the source. How are you getting audio from the PC to the amp (factory/usb/PCI soundcard, external DAC, etc.)?

Got the Muse M15, very nice, no issues with noise whatsoever. It is very clear, detailed, and the highs extend very well. It can sound thin with large speakers and this is not a surprise given the output. I am building a power supply with spare parts (24,000 uF! power reserve) and a new in line regulator to keep things at 12V. I have at least 5 amps available. This is supposed to give the music some body. Overall, a very good buy. I am scoping out the TA2020s next. I would rate my Muse in the very good + build quality. Only issue I have is that it has an M20 faceplate and it is an M15.

I have a Muse M20 EX with a ta2020 chip inside. I use it with a meanwell 13.8V 4A power supply.

The only thing I can say is that it sounds very, very well. It drives a set of wharfedale diamond 8.4's with a fairly low sensitivity of 86DB. Still the Muse M20 is going strong, with great clear sound and good low's. The volume is more than enough for my small room.

I really recommend the device. It is completely free of any noise that we don't want.
