These power cords emphasize low end but it comes at a cost of sacrificing clarity and top end extension. This is the sound signature no matter the component that’s powered by these cords be it a dac, preamp, amp or streamer.
If you like dark sound go for it. If you just want a bit of warmth and a power cord that works well on DACs, try Audience AU24se-i or more recent models. All of these cords will color the sound. The degree of coloration is what’s different.
