If Calloway is correct, then the Monster Cable ones might have somewhat less of a signature than the adaptors Magnepan sells for $20. I bought them, and they do affect the sound some. Dynamics are increased, but detail is diminished, and overlaid with a tad of distortion. I attribute this to the fact that they are a solid pin, rather than a hollow one like a banana connector. So such a large piece of (mostly) copper will have significant capacitance, even though it's very short, storing current and smearing the timing of the signal a little bit. I've just been tightening the set screw onto my thick spades, which sounds best (since one leg of the spade is able to fit into the little hole). I might reterminate the cable with banana connectors on the speaker end, if I ever find any solid silver ones. I have other speakers with binding posts though, so it's not high on my to-do list...PERHAPS I'LL TRY THE MONSTER ADAPTORS that Corvette-uh...Calloway refers to.
