My amp is 50 watts per channel, so pretty modest. But, my "run" to my

I am not a "nut" for monster cable or magic cable that claims to work
wonders, but I do want very good quality, and use wire that will perform
well at what I believe it a bit of an extended distance. I would also like
a wire "set", that has the banana plugs installed at each end.

You'll pay dearly for someone to add those bananas to a piece of wire. Can you
use basic tools ?

Someone recently recommended a very specific brand and internet site, but
for the life of me I cannot find it.

Can any of you make a recommendation please ?

Brand is entirely unimportant.

Most copper is 'oxygen free' as much as it needs to be anyway.

Just find some nice 14 or 12 gauge that doesn't cost a fortune.
