Thanks, I do believe that you have to think and ruminate about some things, sometimes for a LONG time,
to make any real progress in the unknown.
I am just completing development work on a phono preamp on which I've been thinking, working, and prototyping
for decades. Yes, decades, I think slowly. But 90% of the time has been thinking about it. The lab prototyping
goes rather quickly, especially once a good pcb layout has been worked out and tests well. I've built quite a
number of versions, and learned a lot from listening to them, but the equations don't begin to tell me how it
sounds. In fact, I could not have made much progress just relying on the equations. But now I've got something
that's really cool, and measures quite well also. And if I don't make it through the pandemic, at least I've done that.
I'm going to give a copy of this preamp to a friend from back in college who is seriously into audio, and still uses
the modified tube dynakits that I built for him in the 70s, which are still working well. He's gonna totally freak.
He's been through lots of Marantz etc. but sold them all and went back to the Dynakits because he prefers them.
At least there'll be a copy of this preamp out in the world, if I don't make it to the other side.
Will have thick one piece CNC enclosures made for it eventually, but it's been difficult. We've had to move
three times since 2016, a lot of work. Especially personally carrying all the equipment and thousands of LPs.
The lead base for the inspection microscope is a killer. The moving guy is now a personal friend, and
drools over all my LPs.

I suppose you have some measurements to backup the demonstrated audible differences. Or if it not a difference (A/B) that is to be demonstrated, please point into a picture of a measurement where the effect can be seen on a screen. If this is possible!?

I couldn't find the print article where Lars 'infers' the surround on the purifi actually makes more difference than any of the other improvements but Norman Tracey posted it on another thread
Exploring Purifi Woofer Speaker Builds
It's a youtube video and I've copied Norman's words below in case my link is wrong.
Now again usual pinch of salt but intriguing.

Lead base platform for a stereo inspection microscope, with LED illumination.
Like this one:
Also lead filled speaker stands, with dangerous spikes. Don't set it down on your foot.
Only 24" high and I can barely pick one of them up.

Asked this about ten times in the last year: what is this poorly understood problem? Facts please, not anecdotal opinions.
Not holding my breath for anything substantial, though. I'm expecting the same type or drivel as about "time variant" and a few of other buzzwords you are using liberally all over the place, disregarding their relevance in the context.

Your point is sound, but I disagree with what it suggests. It is enough to focus on what we currently know is most audible, and go down the list as needed. Not all things will need to be addressed.
ie...
^ This (but without implying it has to be expensive as long as you are able to DIY, or unless your SO insists you build a soundproof extension onto your house).
You have misread. He was merely speaking about protecting another from bad "karma".

I concur. Meeting and discussing with nobel prize winners, this is exactly what I find.

That is the truth. The ones I know from Australian National University (ANU) never put on airs. We all come from the same dust. My master-machinist friend worked there (Earth Sciences) and he passed away. He was not a scientist, but they would come to him with all kinds of problems with materials, from diamonds right through to whatever and getting made - solutions, period! The funeral was full of scientists. If you come up with the goods, they don't care. They show respect for your abilities and the fact that he was a great guy.
I guess this much vaunted 'humility', is defined differently in science, once you reach your level? Apparently insight as a virtue, is not valued quite so much?
I am not even sure that makes any sense. Now tell us what you really mean. Why should a humble person be lacking insight? Maybe he is more likely to have insight?
I wish this was my experience as well. :/ The couple I have met in my area were pretty prickly, unfortunately. On the corollary, I can think of one distinguished Academy of Science Fellow (or whatever the highest distinction) that absolutely loved working with students and engaging them as human beings.
Which is to say I've found the whole gamut of personalities within the scientific space, across the spectra of achievement.

A mixture of lead shot and sand does it one part more dangerous, but yeah, very lossy and very heavy.
Yes, you have to get your ego out of the way. You don't matter to the universe.
Your life is for but an instant, and then is gone.
Overconfidence is one of the most common human biases.

Maybe its that the humble are less overconfident?
