Glissando,
I will look into the kimber kable’s 
I do have the speakons with spades on other end with the benchmark cables.
Will let you know if I get cables and bi amp.
huge thanks for the help.

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 $$$

Tomic601,
thanks for the input/ reinforcement!

The purpose of the gas tight crimp is to prevent oxidation.

I should add that I clean the Banana plugs with an anti-oxidant, electronics contact cleaner every time I switch out amps and or speakers. That's every couple of weeks.
I use the contact cleaner on tube sockets too. Something about spending $1K to re-tube the Music Reference RM-9 compelled me to start that years ago.

Glissando,
I use a contact cleaner now. Got suggested it 20+ years ago for two way radio contacts and was astonished at the improvement so have used it on my audio gear but probably not often enough.
