Default A question about audio interconnects for the ones here with such knowledge.

Is 67pF per meter @1Khz a good for a analog interconnect? Thanks.

Gavin,

Nobody else has spoken up. So, I'll take a shot at your question.

67 pF./M. is roughly 20 pF./ft. That's quite satisfactory. Sight unseen, that low number suggests unshielded construction. Unshielded cables are not satisfactory for long runs or in high EMI/RFI level environments.

I guess that it is a balance of virtues (or a balance of compromises) when it comes to cales and impedance. If you want to go co-axial then RG59 is about the capacitance level that you stated.
