I've been reading about how noisy the 5v lines are, especially on PC's, and how such noise can affect the sound, especially when the noisy power is connected to a DAC. $50 USB power cubes and battery banks are often used as a solution. I came across this and am curious if others have tried it or something similar with good results.
