Axiom Home Page Forums General Discussion Advice from Axiom Owners Banana plugs - probably a dumb question :)

The whole banana is electrically active (except the plastic parts, obviously). Sure the more surface which is in contact that better the conduction will be, but being flush with the biding post won't help much, because it's plastic on top too.

You should be fine as is.

But if this is a permanent installation you could go with bare wire. That's one less connection to be made.
