Gmood1, if you thought I was arguing your point, I think you're a little jumpy. Actually, I didn't understand your comment about how bare wire "goes against audiophile thinking." From the posts in this thread so far, it's pretty clear that bare wire is fairly common practice. I use bare wire connections myself.
Anyway, banana plugs have their place, and I like the Z approach (Nordost offers these as alternative to spades) over expanding bananas, which I think are more prone to small contact area. I don't have experience with the controlled comparison that RJA asks about, though.
