$$$ cables and tweaks in general, may or may not make a noticeable improvement in your gear. Depends on the cable and use. Try to stay with something returnable in the event that you either don't see or hear real improvement or it's marginal and hence not worth the extra cost........Sadly a LOT of ridiculous sales hype out there. Trust what you see and hear in your own system.............If I worked for me and I love it, but doesn't work for you..........well, it doesn't work for you, take it back.
