I've yet to find anything that sounds better, in real use, than Planet Waves' Custom Series and not only are they fairly cheap but, most importantly, they're absolutely everywhere, always in stock, and have a better-than-average warranty with great customer service. The #1 thing with cables is dependability and consistency, both in terms of the quality of the cable itself and also the ability to get a 1:1 replacement at short notice with no fuss. Some studio gremlins may (think they) hear a stronger or cleaner signal coming out of a more expensive cable, but I've never spotted it in a live situation and I've had too many fancy, expensive and/or custom cables break mid-show (both as a performer myself and when running house) with no exact back-ups to hand that I simply see no point in bothering with anything that can't be easily stocked up on. Maintaining your connection between your guitar, pedals, amp and speakers is more important than eking out that last 0.1% of your signal. All the venues around here keep a meaty supply of Planet Waves Custom Series on hand, all the shops stock 'em, and they're what I use myself. I've had others of many different brands and (alleged) qualities and nothing beats the dependability of the Planet Waves Custom.
