You did ask the question can you do better?
Maybe ever so slightly. Probability nothing audible but I’m a believer in spending enough to make sure you have no weak links but not buying into the Uber expensive esoteric cords. I absolutely believe there are no audible differences between 2 well made power cords of suitable gauge. That being said, for peace of mind I bought an AQ NRG Z3 14 gauge just in case. Found one new open box for $150. I hear no difference. But I like knowing I have a properly made heavy gauge cord. I’d also be completely happy with a Supra hospital/audiophile grade cord for about $200. If I were you I’d get something like that. Try it out. Then buy a pricey cord you can return if you don’t hear a difference. I sincerely believe you won’t.
