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

Audiofeil; "Now, for every manufacturer to take the time and test their products with every cable/component permutation is impossible."

"Lastly, how would you expect any manufacturer to anticipate every listener's likes/dislikes/preferences?"

Gee, wouldn't it nice to know exactly WHAT cable they DID use to tout the claims/specs they're marketing?
Thanks all for your feedback.....one thing I have done is when I go to Hi End Shows like the CES in Las Vegas, I make note of major mfgs like ARC, Magnepan, Krell, Conrad Johnson etc. to note what power cords they use....after all, they are showcasing their products to the media , their immediate retail customers etc....they seem to use their supplied products...nothing else.

But when it came to interconnects, there was no definitive favorite other than ARC claimed they used their own.

Speaker cables, with biamped Maggie 20.1s were noted to use Valhalla one day and MIT the next....hmmmm.
Conrad Johnson supplies a "high end" power cord with their CT6. It isn't a name brand though. They said it did make a difference and is why they included it.
I'd hazard a guess that most manufacturers don't make aftermarket powercords because they know high-end PC's are a big con. As for "offending" other manufacturers... what have you been smoking?

To answer the original question; any wiring within a component is very short and well shielded from external interference by the component casing. It wouldn't be prohibitively expensive to use silver for such short lengths as someone suggested above; such wire is obviously deemed unnecessary over good copper.

However, if we choose to mix brands in our setup and have varying distances between components, it does make sense to buy high quality shielded cables to get the signal from point A to B as pristine as possible.

I posed a similar question a while back, asking if eliminating interconnects altogether by using fully integrated systems (like the Arcam CD/Pre/power) was an advantage.

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.
