Here are some reasons why I've heard that connectors (e.g., spade, banana) are better than bare wire for attaching speaker cable to a binding post: 1. Much more convenient to attach and detach, especially if bananas. 2. No stray strand of wire to cause a short. 3. Connection doesn't break down over time due to oxidation. 4. No chemical reaction due to dissimilar metals. I completely buy into #1 and #2. The parts I don't understand are #3 and #4. I have recently closely examined many types of banana plugs, and in nearly all of them the bare wire is attached to the plug using friction. Sometimes there are one or two set screws, sometimes a screw-on crimping, and sometimes crimping with a special tool. In a couple of cases the attachment was identical to what happens when bare wire is poked through the hole in the binding post and then the nut is clamped down on it. So, with all of these pressure methods, why is oxidation and chemical reaction less of a problem between wire and plug than between wire and post? (I'm assuming both plug and post are similarly gold plated.) And, with a plug don't you introduce the additional problem of a loose joint between the connector and the post? So, it seems to me that the only proper way to attach the wire to the plug is to solder it. Otherwise, as long as one avoids stray strands and doesn't care about convenience, one might as well just poke the bare wire though the hole in the post. Comments?
