A question about the logic of interconnect cables


This question has always been with me...without a satisfactory answer to date.

Why do we not use the same internal wire ( for interconnects) that manufacturers use which feeds their outputs or inputs internal to their product?? It would seem to me that this wire's quality (regardless of what we use eternally) is a limiting factor in the first place

Example..I have an ARC Tube Preamp and ARC tube amps...why do I need "special " interconnects when in fact, the wire used to feed the output of my XLR preamp output is the same identical wire beyond the xlr input of my amps?

I would appreciate some logic here.....Thanks

>>I'd hazard a guess that most manufacturers don't make aftermarket powercords because they know high-end PC's are a big con.<<

All guesses are somewhat hazardous and yours is erroneous as well. Please read my prior post about manufacturers and aftermarket power cords. It will help you understand more clearly.

Thank you.
Hang on Audiofeil, you've just stated my comments are erroneous but then pointed me back to your previous post which is just assumptions - unless you're a component designer for an established brand, that is.

I'll back my statement up with some evidence...
Cambridge Audio, for example, supply all their components with a standard power cord, yet make a point of NOT including interconnects. That clearly means they have no issue with a standard PC, but know buyers will want to select their own IC.

Now an assumption of my own; I believe that if you were able to look inside most hifi R&D test rooms, every component being tested (and every piece of test equipment too) would be powered by standard good quality 3 pin PC's, not fancy expensive aftermarket PC's.

I know from personal experience that the PC's on recording studio equipment (even in major studios) are all standard off-the-shelf cords; I think these folks might know a little about what affects sound balance.

In fact, if I was a component manufacturer, I'd be embarrased to think my equipment's power supply and components were so fickle that changing a PC could affect it's sound.
True I'm no EE, but there's still room for common sense in audio isn't there?
I was talking to Richard Vandersteen and asked him similar questions as above... As far as power cords are concerned, he agrees they do make a change in the sound, but insists that his powered speakers were designed using the included cords, and as far as he is concerned, that's the intended sound. His internal wire comes from various manufacturers. Tweeters have different electrical requirements than do midrange speakers or woofers, and Vandersteen said that he uses the ones he uses after many listening tests. The result is that for instance his model 5A's as it is shipped from the factory is Vandersteen's statement. Sure it all can be modified, but don't call it Vandersteen.
i have discovered a designer of amps and preamps who also designs cable, including power cords. the company is morrow audio. i suspect if i am diligent, i will find additional instances of electronic manufacturer's who design power cords.

perhaps many designers recognize the fickle nature of the purchasers of their products and want to be able to sell them an amplifier and an after-market power cord.
