What I think is you are using the freebie rubber power cord that came in the box. Probably anything, literally anything, is better than that. But if you are talking about spending money, even only $60, then reading eBay ads is not the way to do it. Nor reading anyone else’s ads for that matter. Nor reading any engineering, materials, geometry, etc stories. Forget all that.
Instead what you do is buy only what you have tried and heard yourself, or read a lot of reviews or user comments, and like what they have to say about how it sounds. Because everything, every wire, power cord, interconnect, or speaker cable, it all totally affects sound quality. Not in some subtle hard to hear way either, but big and obvious, sometimes dramatically so. It depends a lot on what you have in the rest of your system. Not because the power cord needs to be "matched" either. This is BS. Whatever a power cord sounds like, it will sound like no matter what its plugged into. But it matters because you don’t want to spend $500 on a power cord to plug in to charge your iPad. Not because you won’t be able to hear what the $500 power cord can do either, but because at that level you can get a whole lot more with something else.
You probably won’t find many reviews on this particular power cord. What I would do, search around for used power cords by known long term makers like Synergistic Research. There will definitely be reviews, and some very good cords will be old enough you will be able to buy a lot more for your money for a lot less than they cost new. But even then do not buy based on price, but based on reviews. Listener impressions. Only way to go.
