I've always been a meat and potatoes kind of guy. What's good for the telecom industry and others like it is good enough for me. Balanced pairs are best, shielded even better. If line impedance is high, noise suppression is more difficult than if impedance is low. Preamp level signals should be short and shielded, best if balanced but most home gear isn't. High current lines like speaker outputs are obviously less of a problem where noise is concerned, but current carrying capacity and internal resistance is an issue. Sometimes tube amps have other issues with output loads. Negative feedback taken from the output line can sometimes have peculiar side-effects too. But those are beyond a cables discussion.
