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?

This is a great thread of opinions from different people. I personally do not have a set ratio of cable vs equipment. i'll throw out my two cents of worth as well.

The material cost to make a 1M cable may be just a few pennies. This is well known. Though, I consider the following:

1: Can "I, other DIYers or other companies" make the same quality cable for how much it costs the high priced cable company to make it?

2: Even "I, other DIYers or other companies" have the skill and equipment to make it to the high priced factory's spec, will it sound the same as one coming out from that factory?

3: The only way to compare the cable made by "myself, other DIYers or other companies" and the cable made by the high priced cable company is to buy both and compare them in person. Why not just buy one at the first place in stead?

I personally can not make one. I would just let the cable company make my hard earnt money. I don't look at things with how much it costs to make. I look at it's value to me. when the price is below it's value to me, i'll pay for it.

Some people brought up a topic about a $500 cable sounds the same or out performs a $5000. It is their opinion in their system, not mine. The only way to find out whether they are the same or not is to buy both $500 and $5000 cable and compare them by myself. As the power cords i tried, I found the more I pay, the more detail is recovered from music. (I look at the whole audio system as a music recovery unit, degradation started as soon as it was recorded on the media. The whole system is just trying to recover as much detail as the original performance performed. There will not be an equipment performs better than a performer is performing in live.)

There's another topic about whether the price difference worth the performance difference. I would say it varies. It's all depends on how different people look at their money. There are people spending $10000 like spending a $100 bill. In that case, the little performance difference will be worth the price tag to them.

Buying audio gear means buying the experience to me. The more budget I have, the wider range of products I can experience with. While forum reviews provide a great communication interface between different players with different setups, I will only evaluate whether the experience is worth it's price tag or not when I can try it in person. I do not own any expensive cables non equipments but i'm willing to buy them as long as i can afford them. The reason is that it is my hobby. If this cable sounds good to me and I can afford it while i have the gut to take the risk of it sounding below my expectation, why not give it a try.

It is just how audio means to me and i'm working toward to experience as many different equipments as i can.
I have read that many have spent quite a bit in thier systems. My question is, What kind of transformers and power supplies are in these components? I am talking mainly about power cords and conditioners. Maybe a modification to the transformer ( better transformer) or power supply would render better results. It is hard to believe that with the amount invested that the components would not already have top notch discrete components inside. I can see why one would question the investment in power cords and conditioners. Speaker cables and interconnects are a different story.
I wouldn't even worry about power cords except to put a decent budget upgrade on until you have brought the interconnects and speaker wire to a highly improved state
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.
