My speakers have general speaker wire and also an adaptor for RCA which has the two red&white plugs, but the Audiophile 2496, which I have, also has plugs on the end. How do I connect them? Do I just put one of these
Yes, if your speakers have RCA ins then a simple RCA cable like the one you linked to will do fine. I reccomend a medium priced cable. Don't get the super cheap ones, they are not sturdy, but don't get fooled into thinking you need those $150 monster cables. Usually that's overkill. BUT- with an analog signal a beefy cable with gold ends is a good call.
