@audphile1 "Opting into “boutique bargain” brands like Zavfino, Audio Envy, Cullen, etc. will be a guessing game where you will get what you pay for, potentially not going to be able to return due to restocking fees and end up wondering how an Audioquest power cord would sound like with your amp."
I’ve tried audioquest and brands like Cullen. Never do I wonder what an aq cable will sound like. Popular retail brands do not mean better quality. There are advantages, like returns. Eating $20 for a restocking fee with a legitimate boutique cable maker is way cheaper than the mega bucks cable you’re likely to be no more impressed with than the boutique cable. I recommend exploring with an affordable cable at first, if that makes a difference, then move up the ladder.
OP: Cullen makes awesome power cords. Talk to Patrick about trying his Crossover cord for 30 days. He’ll let you return it. It’s as good a cord as I’ve found for under $1k. If you want, I have one for half price you can buy. One more thing, it's a very flexible cable, which is unlike every other cable of like quality and capability.
Decware makes excellent cables as well. Their shielded cable looks and feels identical to the Cullen Crossover, yet costs nearly twice as much at $400, which is still a bargain compared to Audience, AQ and others
Good luck in your search.
