Zap 2 speaker cables by MIT

I'm trying to figure out if these speaker cables are high quality. I got them used with a Yamaha RX-777 receiver and a set of Definitive Technology DR 7 speakers. I really don't know anything about them. Except I got them from an 80 year old man. Who told me they were very good. I cut the ends off them. So I could use banana plugs. They just had hooks and straight pin type connectors on them before. Looks like they have about a 14ga. wire inside. Does anyone know about these speaker cables? Zap 2 speaker cables by MIT. MIT? Whats that all about. Sorry I'm not much of an audiophile.
