Hifidreams,
BFA (British Federation of Audio) plugs are not the same as banana's.
They are almost completely opposite of a banana plug. They receive something like a banana, but slightlty smaller, which is inside a protected covering within the amp or component. They were designed, if you can beleive this, to stop people from connecting banana plugs into British power outlets!!!
Please don't put your speaker wire into any power outlets folks!!
