I'm going through a similar process right now as I need a power cord for a new phono preamp. I've currently got a Shunyata Venom power cord on a Denafrips Pontus II DAC and have previously listened to the following power cords: I might use the Shunyata power cord on the phono preamp if I find something else that works well on my DAC, use the new power cord on the phono preamp, or just buy a second Shunyata power cord.
Tripp-Lite Heavy Duty: $15
Shunyata Venom V14: $135
Audience F3 Forte: $150
Synergistic Research UEF Blue: $499
Audiophile AC Power Cable - WAudio 10AWG HiFi Power Cord 3.3FT
Pangea AC-14
In the $100-150 price range, I think the Shunyata Venom is good, but your experience might vary depending on the DAC you're using it with. I've not tried an AC-14 SE yet but that's on my list to try next along with the Audioquest power cords in the same price range.
