Hello,
You have a really nice system. Sometimes I look for what used gear is sold on the different websites and see which one people are trying to get rid of the most. If the market is flooded with it I would stay away. On the flip side if it is hard to find mass marketed product in the used market it is very likely most people love that model. A lot of PS Audio power cables are for sale on the market. I believe the like a solid core power cable. A lot of manufacturers use stranded cables. I personally have Nordost Blue Heaven power cables. If you have something that draws a lot of power Like an amp you will need a thicker awg cable. Everything else you can use standard cable. I know it is expensive but you get one shot to get it right so make sure you can do an A-B comparison and that you have it in writing you are allowed to return the cable in a limited amount of time. You might want to wait until this pandemic is under control so you don’t run into issues. Most companies are running on skeleton crews or working from home and the mail is even running a little slow. Possibly use Amex for the credit card so you have a company that can back you up and purchase the items at the beginning of your billing cycle so the money does not come out of pocket right away or at all.
