I've listened to a range of power cords on a Denafrips Pontus II DAC. Of these, the $95 Supra LoRad power cord was the best sounding of all of the cords that I list below. Surprisingly, power cords seem to make a bigger difference to my ear on my DAC than they do on my phono preamp.
The $15 Tripp-Lite Heavy Duty power cord actually sounds surprisingly decent (about 75% of the sound quality of the Shunyata Venom V14 power cord). Of these power cords, the WAudio and the Audience F3 Forte did not sound good at all on my DAC.
Tripp-Lite Heavy Duty: $15
Audiophile AC Power Cable - WAudio 10AWG HiFi Power Cord 3.3FT : $35.99
Pangea AC-14: $44.95
Pangea AC-14 SE MkII: $79.95
Supra LoRad: $91
Shunyata Venom V14: $135
Audience F3 Forte: $150
Synergistic Research UEF Blue: $499
Shunyata Research Venom V10 NR: $600
