Email EJ (Wyred) and ask him if they use their P-1 Ultra power cord on their dac. It's the only power cord they make. If not, maybe he'll suggest something.
Power Cord for Wyred 4 Sound DAC2
if you've tried aftermarket power cords on the Wyred 4 Sound DAC2 i'd love to hear from you. i'm not sure if this piece is sensitive to power cords, though i've heard the Wyred amps are. i'm using mine as a DAC and preamp and was thinking about trying an aftermarket PC. if you've gone down this path, i'd be grateful for your inputs.
