People I know who have been focused on cables for many years basically take this approach -- they establish a price point around which to try several, they get someone like the CableCo or others to send them a few pairs to compare, then they listen attentively and return either all of them or all but one. A good dealer will be able to at least attach an adjective to a cable, as MC did above, and then it's up to you to negotiate a trial.
In my case, I took what seemed like a good recommendation, found it used (50% off or more) and when I heard it, it sounded fine and I have just moved on. I went with Analysis plus cables.
