A gas tight spade is best, see Vandersteen model 7
i am running a shotgun bi-wire TC-12 on the TREO CT ( Kimber makes the spademaster but you have to tweak to fit Vandersteen ) and I run the silver Audioquest ( essentially Wild Blue Yonder ) with the 7’s.
the Kimber is good wire at a reasonable $$$
