You are reading too many audiophile magazines. Why not trying some electrical engineering texts if you really want to learn this stuff.
1) Yes, I have seen those jitter demonstrations from audiophile magazines. One I remember in particular showed jitter causing inter modulation components, which is what jitter does. However it was 140db down from reference level. Now if the magazine author and the audiophiles who soaked it up were to have studied electrical engineering, they would realize no human can hear -140db from reference. No speaker ever made is that sensitive either. And no power amplifier has a noise floor even close to that - especially a tube amp, and a SET is worse yet in terms of noise floor.
2) Malcolm Hawksford discovered nothing that has not been known since at least the 1920s. Skin effect is well known and does occur above DC, even at 0.1hz. However did the audiophile rag where you read that show any quantified numbers. If you do the math and understand electrical engineering basics, you will easily see how skin effect at 20khz is irrelevant.

I believe the jitter issue has been addressed in the AES so I will see what I can find...not just audiophile magazines.
Again, I will see if I can find the information because it was not in an audiophile "rag" as you put it.
Yes, it has been covered by AES and other standards bodies.The issue is in the numbers. The scale of magnitude. "Throwing deck chairs off the Titanic" or the more modern version, "throwing file folders out of the WTC" comes to mind.
Please do research the AES. You will find they stick to standard established electronic theory as a large majority.
