Just hook them up and play them. After 1000 hours you won't know the difference. Some will say it's the dielectric that is being conditioned, because wire is wire, comparing apples to apples.
We have a lot of the same taste in music cask. Billy Cobham on your set-up must be phenomenal!
I will add prog rock including ELP and Yes, plus Zappa, Zevon, Stevie Ray Vaughan, Chick Corea, Count Basie, Gypsy Kings, Moody Blues...
Search this forum, especially in the ht section, I've seen some decent solutions. Personally I went through the walls into the attic and back down, and yes parts were a pita. The fish tape properly secured would go between cross studs and the drywall with patience and effort.
Search around there are products which are made for this and are paintable for maximum blending. If you get really ambitious and own the place you might investigate going up into the wall and back down the desired wall location. A fish tape wire and a hole drill bit are good tools for this.
At first I thought you were looking at Pipedreams. Five feet is a little short for a nice soundstage, twelve will be much nicer, can you run a covered wire over the door trim?
So the rationale for this is that the animal only eats the best, yet passes it through as a brewable bean. It's a premium bean, except its been through the digestive tract of an animal. Sounds like you'd be better off picking the best beans yourself and skip the excremental process. Of course human error then comes into play but ffs it's only coffee. No I have not tried it.

If you like single point drivers then find a way to listen to a pair of Maxxhorns. They are huge and sound great at close distance as well. For that matter Klipschorns sound great at close distances too. Define close for starters, and try to listen to as many different speakers as you can, then try to explain why lesser bass response speakers "blow away" those floorstanders.
