Andrew,
what is you opinion on these banana plugs?
I'd have the best quality banana plugs going, professionally soldered or cold-welded onto the end of the cables.
But then I spend half my life plugging and unplugging stuff, and it's a pain when you pull a plug out and it falls off, or you have to start strippling back wires and twisting them to put on a binding post, only to have them fall out later.
Sonically? I don't think they make a whole lot of difference, though the presence of proper plugs fitted in such a way as to avoid contaminants getting to the cable conductors could prove advantageous in the long term.
