My apologies for misunderstanding!
(I overlooked that you mentioned that you have a digital based system and I just now looked at your signature for equipment.)
I agree with most of your post. I am also not wedded to perfect measurements, even though measurements are useful. I have a tube preamp and amp, which by definition do not measure as well as competent solid state. Like you I also have an R2R DAC, which by definition doesn't measure as well as delta sigma.
Here is an ad by Schiit in Stereophile about an earlier version of my DAC:, after John Atkinson had called the DAC "obsolete":

The fine print in the left hand lower corner says:
That’s what some have called Yggdrasil.
Why? Because Yggdrasil uses 20-bit D/A converters. But you know, pretty much everything we do is obsolete. Heck, a lot of our products use tubes. And we stubbornly cling to discrete design, Class A and AB topologies, and physical knobs, switches and potentiometers. And you know, we’re 100 % cool with that.
(And if you really, really want a "non-obsolete", "32-bit" DAC, you can save $ 2,200 and get our $ 99 Modi 2 with the AK4490 converter.)
