older speaker connectors

Cardas copper/unplated.Cheapest was found at The Cable Company,for the price they covered shipment from Cardas Audio.

i'll break rank here and tell you pins are fine

What model speakers are we talking about? The cost of the upgrade with Cardas connectors may cost more than your speakers are worth. There are a lot of connectors available at reasonable prices.
Check this site out for some reasonable terminals. I've used them a couple of times, good service. Changing the posts is really not a diffivult little project.

If the labour doesn't cost alot, why not? It most likely will make them sound better. But then...you'll need to change the wire conectors and then you'll want to upgrade your amp, source etc.. Before you know it you'll be spending a fortune and you'll never get the pleasure out of your system as you did before you started all this. (BTW, BP Hex's are excellent binding posts just in case you decide to change them out.)
