Emily, mit reconfigured some speaker wire for me, went from biwire to single for thiels, cost was $100, I'm guessing retermination is cheaper. I've used bare wire and IMO you can't really tighten down the connections enough without almost breaking the wire and it is also cleaner and safer to have terminations, then you have to worry about oxidation every few months.
Modification of speaker cables
I have a set of MIT's 750 biwire speaker cables. They are terminated with spades. I have just purchased a new amp that has binding posts that are larger than the spades will fit. Will there be any negatives to removing the spades and going with the bare wire? (other than resale value)
