Edison binding posts are the way to go. They are quite soft, pure copper, if memory serves me right, and you can easily over-tighten and strip the threads; happened to me on another speaker. I have not heard a fully tricked out Maggie in years but I believe they can be made to go up several levels of excellence for a reasonable outlay. Everything is pretty easy to access and the circuitry simple. There was a wonderful site somewhere dedicated to all of this. Lost the link but it shouldn't be hard to find. He suggests taking the cross-over off the speaker, in a dedicated box, and it being so accessible, it's very easy to swap out caps until you get the right sound. This is definitely on my lust list. My first encounter with Maggies is what got me into this craziness in the first place!
