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?

In blind test I would bet anything you could not pic Radio shack spoole wire form the The crazy 1K plus cables. Any money. Snake oil is snake oil. I dont need to brag on spending 5k on wire. To many on this site do.

Now, that's quite a generalization! It would do you good to find out which cheap products deliver and which ones do not. In my system I use 65 cents/foot military surplus signal transmission cable as speaker wire yet handcrafted, naturally insulated silver interconnects.

My system is resolving enough that anyone can tell apart same models of a power cable treated at different cryogenic facilities. My system is gentle enough that it can successfully play any recording of any musical genre regardless of recording quality.

I'll throw-in my 2 cents worth (maybe it's already been said, I didn't read all 135 responses up to this point!). Power cords can make or break a system IMHO. Some cords that come with your components are fine as is (i.e.: Audio Note Japan pre-amps, their KSL-SPz AC cord is fine, no need to upgrade). Most gear a great AC cord will have a very positive effect and you don't need to spend huge amounts of $$$ to get a great power cord. Example: Z-Cables made (I say made because as of several weeks ago Z-Cables closed shop do to personal health issues... and YES, Mark is doing well now) a $600 Black & Red Lighting AC cord that actually beat out most mega buck cords or at least performed as well. I've listened to dozens of power cords, they all make differences (again as a qualifier, your system has to be capable to hear all these, sometimes subtle changes, but in the end it's trial and error. You have to experiment or trust your dealer.
a cable(power/speaker/inter connector) is only worth what it will bring in the after market. example if a cable lists for $1000.00 and you can get a 25% disc costing you $750.00. then when you go to sell on audiogon and you can get $550.00-$750.00 back the cable was worth the price. if you payed $900.00 for the same cable and had to sell it for $450.00 or less, not a value in my mind. and the lower you most go the lower the ultimate value. so its not the price but the % of your original investment you can recover that determines the real $ value. so if you buy $8500.00 list spraker cables for $5700.00 and a few yrs of enjoyment or dislike later, and you can recover 80 to 100% of your money paid, well you did ok. obviously the closer to the 100% the beter. thats the way i see it anyway. you should research resale value first, then consider buying.
My experience with JPS shows good bang for the buck value and superb performance.
