Well, it was worth a try, Thanks Danny!
(but if you decide to sell, I'd be interested
)
My long ones are just like these but are a 9 foot pair.

They have Vampire's best ends. See Vampire website. They sell for $75 per pair, but worth it. But I used them without the barrel over them. They sound better without the barrel added.
These use two pairs of Vampire Wire's 18 gauge continuous caste Copper. They are in a counter rotating braid around a polyethylene tubing core.
And yes, they take a LONG time to make. It is lots of braiding.
These are my favorite long RCA's, but I just don't need long RCA's anymore.
I'll take $450 for the pair, and that's a steal. If I don't sell them then I might cut them in half and make two pairs of RCA's out of them.
