Nice to see people like yourself bringing critical thinking to MG’s claims.
They apparently don’t allow too much critical thinking on Michael’s forum. Skeptical challenges to their ideas - simple things like asking for measured results for some of the more controversial claims, listening tests constructed to control for the variables of people’s imagination etc - are frowned upon as "bad vibes" and a sign one is not being sufficiently open minded. (You’ll find exactly this attitude on any number of fringe medicine, New Age, psychic medium, astrology, etc groups...funny enough).
There isn’t the luxury of of fan-worship and lack of skepticism when he brings his claims here. (Though I’d like to be wrong insofar as he could actually substantiate some of his claims). So I’m sure it’s not as comfortable for those claims to be brought here.
But then: A wise university professor pointed out: Discomfort is a sign that something that you think is right, is being challenged. And that should be exactly what you want, because that’s exactly when you are most likely to be on the cusp you are learning either that you are wrong - or by taking on the challenge you gain more confidence you are right. One can either take that opportunity to be challenged and learn from it, or use the discomfort to declare those who challenge your claims as "trolls" as a way of running from the challenges.
As for how the crowding of the electronic parts producing crowding of the soundstage, you’ll find quite a bit of these folksy-level "explanations" in MGs stuff. For instance he’s written how running wires close together would produce a "tighter" sound, a bit more apart will yield a bit more open sound, moving further apart yielding even more open sound.
As I said, it’s something of a piece of the folk-wisdom behind homeopathy - the same conceptual appeal of "like cures like" (even though there is no actual basis for the claims made on this hypothesizing).
