Looks like some company was really embarrassed someone would show that they added too many zeros to their product price...

Apparently they sent the device in themselves. I suppose they were expecting "cup the balls" sponsored content treatment rather than an unbiased video.

Clough42 gets free 3D printers from manufacturers sometimes to review, and every once in a while he tears the product a new one. And every once in a while the company actually uses said negative feedback to improve the product

The 3D printer market isn't based on selling $20 cables for $3k based on some bullshit pseudo-science marketing.

I remember the first time I saw audiophile cables that had an "electron flow direction" marked on them and I kinda knew right then what this was all about.

Even leads for monitoring brain activity don't do that stuff. And they are monitoring literally mV. Leads and contact patches are often made of silver to capture that stuff too, and they have actual reasons to use silver.

For medical devices, they're profitable by being based on reality instead of just bullshit.

Far lower than that. Most EEGs at the scalp are in the 10-100 µV range.

This company is also guilty of some silly cable marketing: https://www.audiodesign.co.uk/styled-26/styled-21/index.html

In this case, Mark tried to give them the benefit of the doubt, explaining that even if the circuit is a reference design, spending time to match components might make it better than it would be otherwise. It wasn't a bashing, but seemed like a repair video in good faith.

Reading the website of the guy who sells the amps, it's clear he has some ego issues:

I'm guessing he expected to see Mark fail to repair it, and instead talk about how amazing and advanced his product is.
