OP,
Thank you for your post. I had gotten a couple of Shunyata Venom power cords a few years ago… just needing some and not having the time to do any research. I found them to be no better than stock cords. I was really disappointed. It is not like Shunyata isn’t a well respected brand.
Good to hear that higher level cords are significantly better. I know my AudioQuest Hurricane is simply stunning.
Your post got me thinking… reminding me that I had left a Cardas Clear Beyond on my preamp (for the last year), but I had a Transparent Ultra (current generation) in my pile of spare power cords. Typically Transparent sounds better on my equipment (under my UserID). So, I switched. More detailed, very quiet. I’ll have to give it a few days to verify, but both great power cords.
