Competent digital engineers don't necessarily chase the best measurements, even though some of them do.
Mike Moffat, formerly the digital engineer of Theta Digital and now chief digital engineer at Schiit, does not like the sound of delta sigma. He prefers making R2R DACs, and Schiit's top models (Yggdrasil in three different flavors) are all R2R. Moffat will readily admit that his entry-level DACs (I think priced at $129), which are delta sigma, have (far) better measurements in several parameters than his much more expensive top level R2R DACs (well, expensive is relative at max. $2,600). But he doesn't care. He wants his best sounding DACs (R2R) to have the best measurements that he can engineer them with, but just for measurements' sake he would never switch to delta sigma for his top offerings.
He *is* concerned about DAC linearity, and for this reason chose for his Yggdrasil OG an expensive DAC chip for precision applications (military, medical) that is not recommended by the manufacturer (Analog Devices) for audio applications due to zero crossing glitch energy. Moffat solved that glitch energy problem for the audio application in the Yggdrasil (1 kHz sine wave at -90 dB measures perfectly).
Interestingly, the one of Schiit's three Yggdrasil variations that measures best also sounds the worst, according to what seems broad consensus.

Yggdrasil Less is More.
Even better performance for lower cost. The most affordable Yggdrasil uses four TI DAC8812 16-bit D/A converters. Many think this is the best sounding flavor, hence less bits, more better…less is more.
Yggdrasil More is Less.
The best-measuring integrated multibit DAC, ever. This Yggy uses four TI DAC11001 20-bit D/A converters. If you’re one who thinks multibit DACs can’t measure well, this one’s for you—approaching -120dB THD+N.
Yggdrasil OG.
The Yggdrasil you’ve loved for years, same as it ever was. The original Yggdrasil with four AD5791 20-bit D/A converters remains in the line, because it provides an exceptionally engaging performance.

Several other digital engineers who also prefer the sound of R2R ladder DACs probably think similarly about measurements vs sound as Mike Moffat does.
