Power cord - 5 ft vs 10 ft ?

10 ft is too long in my book. Sweet spot is 6 ft.

Jim from wisdom cable recommends 2 meters.He is very knowledgeable.

Jasonborne plainly he does not believe cable can make the system sound better, I respect that? Yes Thymame I also notice Jasonborne either he is first or second to post.

Long enough to connect without straining, large enough to carry the required load, and as well insulated as you can afford/justify within reason.  I run 6 foot AudioQuest NRG-4 to my PS Audio Powerplants and 3 foot AudioQuest NRG-2 from the Powerplants to the components.  Sounds wonderful without breaking the bank.

It's not the length so much as the girth that's important.
