Power cords... Put fancy power cords on a LPS that feeds a DAC and on one on another LPS that feeds a fancy streamer. LPS's got super hot. Sound was straight crap, and I just knew I'd be sending the DAC and the streamer back.
Then for sh!ts and giggles I replaced the fancy power cords with the wimpy power cords that came with the LPS's and the LPS's cooled down and the crap sound turned to pure bliss.
