I have not tried the Diamondbacks, but I have two old-model (lavender jacket from about nine years ago) Shunyata Sidewinder cables that can be had for around $125-$140 when they periodically crop up on Audiogon. I have used them with CD players, preamps and amps, all to good effect. Considering the price, to my ear they offer a surprising measure of the noise reduction and increased detail that Shunyata's more expensive cables provide. But they might not be for everyone. Your post spurred me to look at what people have said on audioreview.com, and there is a detailed review at the top of the list that I agree with. They are a touch forward, edgy and energetic, which I personally like.
