The difference between monster and any other cable of the same length is pretty damn negligable. Id save my money all together. I dont care what anyone says. Theres only 1 thing that makes Monster cable worth it. It aint sound and it aint quality. It is the unlimited lifetime warrenty. If ever your cable breaks or is faulty, bring it to a dealer and get a new one. Period.
As far as Im concerned the topic of which high end cable sounds the best is moot. As long as theres, at the minimum, a decent quality to materials and construction, I doubt that 95% of the people here could tell the difference. What I get more concerned with is how well it stands up to use & abuse.
This topic always resurfaces. Is monster cable worth it? Is the better monster cable worth the extra $$$? I used to use monster cable for the one reason I stated. I thought it was great that you can just go and get a new one no questions asked. And I did. Pleny of times. Which became my problem. Monster cable doesnt last very long under demanding conditions. It just became annoying. Then I got into George L's. I bought 100' length 4 years ago with 10 tips and I havent had a problem since. GL's has a much better "built in" warranty. That is if the tip breaks, just take the tip off, cut the cable an inch back, and put a new one on for a total cost of 5$. Its simple. You can do it right at a gig. If the cable breaks at a gig, itll take you 30 seconds to repair if you brought an extra tip. If you believe gold tips make any kind of difference you can buy the gold tips for 6$ instead of the plain or nickel ones for 4$. Ive rarely needed to do that though. Unlike the monster, which lasted an average of about 8 months per cable, my 4 GL's are still here. Its also comforting that Guitar Player and Eric Johnson think it sounds the best also. For a total cost of about 25$ per cable.
My advice is the same as Glen and Guitarlos2's.
