Wow you got a lot of crazy responses. Don't make this rocket science cause it aint. First, demo some cables in a reasonable price range and see what works best in your system. If you are using very high-end gear to begin with, you should not have to spend That much on cables and I would advise against it. For example, I have listened to both Linn and Simaudio gear with Musaeus (an inexpensive cable) and I would not ever bother to go much beyond it with that gear. You will spend tons of $$$$ for an incremental improvement. By all means experiment but, Dont go crazy. IMO Purist offers great value in their entry to mid level cables. So does Kimber. Good luck.
Cable Costs Relative to System
Since making a spread sheet with my audio system prices, I have been thinking(shocked) about my total investment in cables. My total system retails at $67,000 (Digital and analog front ends included). I purchased all of it here on Audiogon so my investment is about 50%. Of that I have about 10% invested in interconnects and cables and another 10% in Power Cables (Shunyata Hydra included). That's $13,000 worth of wire. I'm starting to question whether it might be more effective to put some of this budget into acitve components. It would take forever to listen to all possible combinations, but would like to hear others experiences with relatively high end systems and cable selection. It would seem to me that the point of diminishing returns would be reached sooner with cables than with speakers and amps. Do most of you follow the 10% "rule" for cabling? How do PCs fit into this rule? Are there any super bargain cables capable of keeping up with highly resolving electronics?
