No need to get any banana plugs, bare wire is the easiest(sometimes) way to connect every thing, especially for flush mounting the QS series of speakers as they sit too close to the wall to get banana plugs into the terminals.

I usually run banana plugs for the wiring on the back of the receiver and at the speaker end on my mains and center as I tend to swap out my M80s/VP150 for my M22s/VP100 once in a while.
