Default Re: Audiophoolery. 'Cable Break In' - I never knew that!

Yes, That is true I agree due to resonance effects the cartridge inductance with certain length cables and their exact capacity. But if the capacitive loading is high enough there will be HF roll off too.

In any case, this represents a problem where the output of a device, be it a transducer like a cartridge or microphone or pickup, really has an impedance that is too high and a frequency response profile that can be affected by loading from a real cable, be it resonances or damping. Ideally the turntable cartridge, or a microphone or guitar pickup, or a signal source from any unit would have a buffer in it and drop the output impedance to a sensibly low value prior to driving "the cable" and then we wouldn't have to worry about cable length & capacity issues as much.

In some controlled professional audio work it is attended to with 600 Ohm systems and balanced lines too, but in a lot of audio equipment and especially with instruments like guitars a lot less attention is paid to the issue so people start noticing the effects of the cables, and generalizing those experiences to every other situation involving a cable.
