CJR,
I eliminated the binding posts in my system, pretty much as you described, on both the amp and speaker ends, and I think I heard a difference. Since I did not feel like A/Bing the two configurations, it is a little hard to tell, because you listen, spend 30 minutes modding it, then listen again.
Maybe it's because I did the work, so I wanted to hear it, but I have made other changes where I did not really hear a diff, and I expected too.
Was worth it to me, if you don't mind drilling some holes in your stuff. The speaker end is easy, amp was harder because you have to drill through metal.
As for speaker cables, ETR, go visit Stan some time and see if he will let you borrow some of his speaker cables. I use Stan's recipe, and am happy with them.
