Power Cable Suggestions.

They do make a difference for subs. Power cable for sub is what made me believe that power cords can make a difference. Many years ago I tried one of those Monosaudio/viborg ones from Amazon on my sub. They are $40 and make a noticeable improvement. Try one of those, if you don't hear an improvement, its just $40 that you can always return.

@jasonbourne71  Agree completely, upgrading a power cable won't do anything unless you are using something really crappy.  However, I bought these just for the bling.  They claim to be OCC and 10 AWG although the Chinese have been known to lie a time or two.

I have the DH Labs Corona and Red Wave, bought each of them on sale. Every month something is discounted. I bought these years before any of the cryo stuff was out. The difference between them and the factory power cables was very noticeable.

I recommend auditioning each cable in your system, bearing in mind that most power cords will not reveal their true potential unless they've been broken in for at least 200-500 hours.

And those who say they can't hear differences in power cables have very low tier systems or rooms or have never tried it and are just internet armchair pundits.

Let's face it, their main problem is they can't even afford power cables. It is an unfortunate situation, but they brought it upon themselves. They made a lifetime of bad choices that left them with systemic impecuniousness, class envy and populist anger. They are best left ignored; do not engage them lest they lash out.
