Agree. It would be painstakingly difficult and expensive to source extremely high precision discrete resistors especially for the lower significant bits.... AND have them all track precisely over temperature. Laser trimmed on a chip would be better all around. Going fully 'discrete' is more of a novelty in this day and age, IMHO.
Spinning Schiit:
"Forget everything you know about DACs. Yggdrasil is the world's only closed-form multibit DAC, delivering 21 bits of resolution with no guessing anywhere in the digital or analog path. We've thrown out delta-sigma D/As and traditional digital filters to preserve the original samples all the way through from input to output. Let's take a closer look:
21 Bits, No Guessing: Mission-Critical D/A Technology
When doctors are trying to diagnose whether you have gas or cancer from MRI results, or when the military is trying to ensure a missile hits an ammo dump and not a nunnery next door, they don't use "24 bit" or "32 bit" delta-sigma D/A converters. Instead, they rely on precision, multibit ladder DACs, like the Analog Devices AD5791. This allows them the bit-perfect precision they need for critical applications, rather than the guesswork of a delta-sigma. We chose this same critical technology for Yggdrasil. Following these unique D/A converters are sophisticated discrete JFET buffers and summers."
