I have a UPS (uninterruptible power supply) which I use to connect a lot of my electronic devices. I've read many comments saying that audio equipment should not be plugged into one, as they can distort the sound, so I've plugged both my amp and DAC directly into wall outlets.
 
However, would there be any sound quality difference if PC is plugged into the UPS instead of the wall? The PC is outputting to a Schiit Gungnir DAC via USB 2.0.
 
Thanks.
