As for the distributed schemes I posted tables for - the Focusrite desks you referenced used it, the big Neve VR's did, as did some higher end Soundcraft desks.
I addressed this in my 1980 console design article.
I'd personally like to hear from any of the folks here that say this scene won't help noise from the summing amps to show why 'Small Signal Audio Design' got it wrong.
As Abbey's signature says, it isn't about who's right, but what's right.
Not wrong, but perhaps not significant... As has been shared by more than just me, other noise sources will dominate the noise floor in use, so don't get fixated on optimizing that one variable (bus amp ein) while ignoring the rest.
Distributing across multiple bus amps would also improve the phase shift/distortion issue caused by inadequate loop gain margin, that I am actually concerned about.
Extensive modification could hurt the resale value of the console (but perhaps that ship has already sailed). Limiting tweaks to just the master bus sum amp would be easier to unwind, and keep the strips relatively stock. I have already given my best suggestions and even I am tired of hearing them, so I won't bore ya'll .
