Just remember that no cable ADDs to your tone, it only takes away!
In some cases, that's of course desirable (uber long cables taking the top end off, trying to emulate someone famous, case in point).
Most of the time, it's not desirable.
I found that the ClearTone cables take away far less than the Planetwaves cables. Incidentally, they are also cheaper. I would be *very* surprised if a £200 cable would take away so much less than the Cleartones to make it worthwhile on any level (unless I were given such a cable, if it really is superior!).
I am biased, of course, because I don't have one of these expensive cables, and I'd rather not have to worry about saving up over £1200 to spend on them should they really turn out better...
But by the same token, all cables break, and as long as I have a source of high quality cables at really rock bottom prices, I'm very happy :)
