I think they're worth every penny paid for them. They're all pretty bog standard coax cable with good connectors, excepting Signal Cable's Silver Resolution which is an air dielectric two conductor cable, which is what I'd recommend trying and the cable mentioned by decal and MM. Coax cables can give a nice, balanced sound, but don't compare to better designs in my eyes. That doesn't mean they have to be a lot more expensive as evidenced by the Silver Resolution's price.
