Power cable education needed

The info at this link might be helpful. Other than replacing one to correct "inadequate" gauge, I thought power cords making an audible difference was silliness...that is, until I heard an unmistakable improvement switching from a Pangea AC-9 (7awg?) to a Shunyata Venom HC on a Class D amp. The "flat earthers" can rant all they want, I don’t care about convincing them. Decide for yourself. I like Shunyata. There are other options. Rent something (or some things) from The Cable Co. and try on power conditioner (a bigger impact than on the amp), or amp, pre, source, etc.. Experiment. Let your ears decide. Does a system have to be at a certain level of "refinement" for power cords to make a noticeable difference? Maybe. But I can only speak about my experience with my system which, on the continuum of audiophile gear, is mid-fi at best.

One more suggestion. Seems like power cords by "Audio Envy" are getting a lot of positive buzz around here. I haven’t tried them but an audio-bud has them and by comparison to more expensive cords, he found them much better. There’s at least one thread about Audio Envy on A’gon. Might make some interesting reading for you.

My three rules of audio: 1) There’s always something better sounding out there. 2) You can always spend more. 3) #2 does not guarantee arrival at #1.

Good luck, have fun and hope you find something that lets you enjoy your music even more.
