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 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.
Given that once a customer buys the equipment, he/she is likely to then try a range of cables to integrate the new component in the system, and since the ideal cable arrived at will likely be driven by overall system balance and the other equipment as much as by the new component, it seems obvious to me that including expensive cabling with the component is potentially a large waste of money.

But that assumes you believe in the importance of well designed and selected cabling. If you don't, then why are you bothering to ask the question?
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.
Carl109, your only evidence is that the Cambridge Audio or Creek gear do not respond to sonic changes with varying power cords. That's an indication of the electronics here, not that power cables are a con.

This would be like someone expecting that putting 91-octane gasoline into a Toyota Corolla would make a performance improvement compared to the 85/87-octane that was "recommended" by the manufacturer. The user would detect no change and therefore there is evidence that higher octane gasoline was a con. NOT!

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.
There are pros/cons of integrated vs. separates but it's not going to be because of the use or not use of ICs....other than a cost issue. I would suggest that you consider moving up to the next level of performance in your electronics choices before you put any attention to cables. Until then, you will continue to convince yourself that cables are a con.
hi jafox:

suppose a machanic working for a toyota dealership tells you not to use premium gas ?

or suppose a manufacturer tells you not to use an after market power cord or not to use a power conditioner with his product, or not to replace the tubes, as cj does ?

do you follow the lead of the manufacturer or do you ignore the manufacturer ?
