I'm using a benchmark DAC1 USB and have zero complaints with the sound. My laptop and 750gig external hard drive are on the same breaker and sit less than 4 feet from my rig (my amp is sharing the same outlet with my computer). DAC is fed by a 6' USB cable.
mixing/matching ICs and power cords can do A LOT to calm down any edge/siblance associated with 16bit digital from the computer through the 24-bit upsampling DAC.
