1+ ptss, Equi-Tech uses a balanced topology with their transformers so they cancel noise, any noise just like a balanced pre amp circuit. I use a 1.5 RQ on my low level and digital stuff and it is faultless. It will also last longer than I will. They do make them much larger for amplifiers but it gets expensive and IMHO power amps are less sensitive to line garbage. My opinion here is colored as the electrical company forced me into paying for my own line transformer because of my work shop when I built this house. They did not want me dimming everyone else's lights. So, I probably have less garbage to begin with. I do think the 1.5 RQ made a difference sonically but it is a subtle one. For computer audio it is a must.
I use an Apple Mini with a 6 TB hard drive run by Pure Music and it use to crash every two to three hours or so. Now it might crash once a week. That is a big difference and when I unplug it from the 1.5 RQ it goes right back to crashing every two hours. Go figure.
