Ian - I was totally serious.

What we do as hobbyists with system optimization tweaks is totally disconnected from the reality of audio engineering and manufacturing.

The standard of proof in audio engineering and manufacturing is substantially higher than it is for audio hobbyists who only need to satisfy themselves that the change they made in substituting a valve or a fuse is worth the investment.

I have no doubt that the people substituting SR Blue fuses for bog standard OEM fuses are hearing an improvement.

So to be clear I am not belittling their pursuit of better sound. Far from it.

I know there are things I hear that I don’t understand or can’t measure. It’s part of the fun of the hobby.

I do seek to understand what makes things ‘tick’ and try to separate real improvements from illusory ones.

My other point was about supply chain - for a manufacturer surety of supply is critical, along with the reliability and consistency of the component. That’s what will drive a manufacturer to use a certain part over one that, to some people’s ears, may sound better.
