Well yes and one might point out that Ken posts the pseudo-technical drivel because without it, even the dumbest reader would immediately see that he was dressing up opinion as fact.
I would venture to suggest that the jigsaw analogy is not really the most objectionable part of that passage- the implicit suggestio falsi is that the analogue recording (let alone a copy of it) could ever be a perfect facsimile of the original or that the process of encoding sound pressure as voltage levels, voltage levels as arrangements of magnetic particles, magnetic particles as grooves in vinyl is somehow natural and perfect.
This is not a quibble, he literally can’t make his “point” without the background nonsense.
Ps- if a digital recording is like a jigsaw, then how come a digital picture isn’t?
