DIY power cable questions

If all you want is to get electricity from the wall to the component then go for it. But if sound quality is even a small concern then search around and buy something used. Whatever amount of money you plan on spending on DIY, spend it on something already built instead. Because it will be better than anything you can make for that amount of money- and not by a little. A lot better.

Sorry, but this is the best advice I can give: don't.

I do not agree, homemade cables can perform incredibly well.  I use Furutech cable, including their TOTL DPS-4.1 cable and NCF connectors.  You will need the right tools, nimble fingers and some serious patience but they can be built and sound incredible.  If you are not patient or dexterous then I suggest you simply buy built cables.  Good luck

Don’t pay bloated prices as many manufacturers’ profit margins are greater than 70% and up.  Cable manufacturers don’t have any secret sauce in their cables that aren’t available to you and me.  Also, many of the the cables being sold and their ‘technology’ are truly snake oil.

Making a homemade cable or buying bulk Furutech I don’t think is the same thing. Agree making a truly homemade cable will probably be a waste of time. Buy bulk cable and terminate your own and maybe save a little money. Check out VH Audio as Chris has a nice selection of cabling and plugs.
