Hi Mark,
I won't admittely embark into building one, but I am as always interested in your findings regarding caps difference at the output, or your view on sonic differences regarding regs technologies.
Many thanks alreday for taking the time to share all this with the community.

There is a working version.
As I have said before, at this point I know too much about the work of my friends who make a living designing high end audio gear. Thus I am not at liberty to share completed designs that have very likely been influenced by their proprietary knowledge. However I am able and willing to assist experimenters who want to gain some practical experience. That's how one learns anyway. One has to learn how to do one's own lab work. IMHO it isn't just about sitting at a computer simming, sitting at a computer selecting parts, sitting at a computer laying out a PCB, etc. Those things may be necessary too but some of the work involves building circuits and listening to what one's circuit choices do to the sound. Measurements are lab work too of course.

Hmmm... That would be Jam, to which business you have no association, of course. And how exactly are you willing to assist experimenters? With "could", "may", "maybe" and "might"?

In case you aren't familiar, what you've read is an internet forum version of "white paper", also known as infomercial. It is written to promote product or service by a company.
Don't forget "IME".
Any engineer worth his salt would ROTFL by the use of “proprietary knowledge” in the quoted context of Transistor Series Voltage Regulator | Error Amplifier Working. In fact, if that’s what high end audio designers are focusing on, then it’s not laughable, it’s rather sad.
Nice, I see lots and lots of
😀
To be more serious again - I find it hard to believe that in a DIY forum asking for schematics and measurements is considered trolling.
OTOH posting an article how a voltage regulator works in principle and depicting that as a project descripting / expecting other people to join in in the design efforts - I would call that trolling, too.
Next thread I open will be called "My secret sauce high performance amplifier" and will have a link to Amplifier Design Basics >> Electronics Notes in it. Just kidding, not my style 🙂
Guys, I'm outta here, it's not funny anymore. And not useful, another thread where N>S.

We should all know by now that typical measurements don't fully predict SQ. Not even AP claims that their machines can measure that. They are only 'figures of merit.' Period.
Regarding schematics: layout matters, target dac chip matters, etc. There is no one-size-fits-all schematic.
You want me to serve you a fish dinner with all the trimmings. I'm only offering to help you learn how to fish. Take it or leave it.

Could you try to explain (or guess) how and especially why it beats your previous designs. Anyhow if this layout is any indication of your IC designs I'm not suprised.
Right, it can't predict personal preferences like the ones you've been posting, i.e. "IME", "better". But this is a sound reproduction domain where better reproduced sound can be documented with measurements.
Wrong analogy. When such dinner is reproduced, your typical impressions don't apply in quality judging. It's the level of resemblance to the original dinner that matters, not your personal preference.
Interesting older posts, "I am a retired EE with a successful career behind me, not a newbie", "I am retired from an non-audio-related career."
From the same old post:
"I give away my findings for free so that diy'ers hopefully can make better dacs."
Which [findings] are, of course, the "could"s, "may"s, "maybe"s and "might"s.
An implementation of an old Wenzel idea: Finesse Voltage Regulator Noise! | Works fine, although it is unclear to me if this principle makes any sense today, when we have ultra low noise LDO regulators. Any discrete implementation would be cheaper and overall better performing.
