I watched this episode, hilariously terrible construction of what I’m sure was a thoughtfully designed amp.
The thing had pcbs stacked using plastic m2.5-like standoffs that had snapped. Apparently the product designer claimed Mark couldn’t fix it. Mend it Mark can fix anything that is fixable, truly a master repairman.
I watched too, and the whole time I was thinking about what Cathode Ray Dude said about high end electronics companies in this episode:

And my own experience working on the design of complex projects as an architect. A good job will still include stupid mistakes when designing a one-off project because there are always gaps in institutional knowledge and time and money constraints.
$25k is a lot of money to spend on home audio. It is not much income even for a side project. Never mind a manufacturing business with engineering and advertising overhead in addition to logistical and fabrication costs...and I think the devices in the video are manufactured in limited annual numbers so there's not even an economics of scale.
I love Mark's channel, but videos that embarrass non-celebrity individuals is not why. Youtube drama doesn't seem to be his strong suit, and while what happened isn't justified, it is not terribly surprising now that I've thought about it.
Anyway, it might have been someone who bought one of those amplifiers who filed the takedown. Because owners were also likely to be embarrassed by the video and also likely to have the wherewithal to file a takedown.
