FWIW, a Synergistic Research UEF blue consistently sounds smoother to me than other power cords I’ve tried (including a $15 Tripp-Lite Heavy Gauge Power Cord) when used on both a Denafrips Ares II DAC & a Pathos integrated amplifiers. My guess is that the Synergistic power cord may be better at channeling or rejecting analog interference such as EMI which can come across as harshness and lack of transparency.
BTW, the $15 Tripp-Lite Heavy Gauge Power Cord sounded pretty decent and was clearly smoother in sound than an $200 Audience forte f3 powerChord. I also tried out a Shunyata Venom that was pretty decent. I haven’t compared the Shunyata enough versus the $15 Tripp-Lite to know which is better because the Synergistic Research cord is just clearly more enjoyable (smoother, more detailed) than all of the other cords. I think the Shunyata and Tripp-Lite aren’t so far apart in sound quality. At least, not to a degree that is clearly evident to me.
I was lucky enough to have the Synergistic, Shunyata, Audience power cords loaned to me by a friend to see IF power cords made a difference that I could hear. Unfortunately, some do & it looks like I will be now several hundred dollars poorer. Haha.
