Adding banana plugs to old speakers - too late?
I recently upgraded my old 5.1 system to a Sony 7.1 STR DH800 Receiver. I kept the old 5.1 Pioneer Speakers (several years old). They are 8" book-shelves that still sound really good, especially after the switch. Two weeks ago I purchased 2 new Polk 8" book-shelves for the rear right and left channels to fill out the 7.1. I connected them (and the old speakers) to the Receiver directly.
I have discovered a lot of internet literautre on banana plugs and how they held prevent against wire corrosion and connection loss and decided that I should at the very least have the plugs for my new rear speaker connections to the Receiver.
My question is in regards to the five old speakers. Is it too late to use banana plugs for them as well? I expect they have already corroded over the years and the plugs may not make much difference. Would it be any better if I cut down into the older wires a bit to expose a new connection (as I have a bit of slack on each speaker)?
Thoughts appreciated.
