Yes, but we have little control over that and most of us can only work with what we've been given

I'm getting the feeling this thread is getting a bit like doctors vs anti-vaxers.

As PMA says, everyone's an 'expert' in the internet age and although 'quiet to 9 digits' using good engineering is good enough for LIGO (where they have to specifically deal with the thermal noise of a few gold atoms bumping around on the laser mirror) its not good enough for audio.

And I have the temerity to I think I'm a hero because I can build a 1nV/rt Hz amplifier . . .

Go figure.

No you are not alone. But for some glomming and glopping things they can get away with avoids looking at the harder to solve issues. If something is below the level of the noise of the blood running through my ears I consider any improvements to be entirely for intellectual challenge (also called Sh*t and giggles).
