Just wondering if anybody has some more insights as to how/why crosstalk occurs? I broadly assume it is mainly HF, but why? LF has more energy in general. Also for sanity sake - can I assume that the main contribution in most circuits is pre-amplification? Pre/post amplification would make a considerable difference if the amplification is non-linear and the adjacent channels have different frequencies.

When two conductors are close together they form a capacitor, so in a real circuit it's like there are tiny capacitors linking everything together, so that's why high frequencies bleed from one place to another (it's worse pre-amplification only because crosstalk going into the pre-amp signal is going to get amplified, and if the crosstalk is from the amplified signal then it's not just crosstalk it's feedback).
