In Reply to: These two (engaging) technical articles cover most of it, for me. posted by jusbe on October 21, 2017 at 23:45:46:
I haven't finished reading the full article, but he is basing his conclusion on an *extremely* faulty assumption - he listened to one ladder DAC chip with a zero feedback analog tube stage, and compared it to three delta-sigma DAC chips with high-feedback op-amps in the analog stage. That is positively insane.
In my experience, the analog output stage is the single most critical factor in the sound of a D/A converter. The DAC chip itself (and the technology used) has perhaps 1/10 of the influence on the overall sound quality. Below is a link to some of the factors that I've found important in the sound quality of a D/A converter.
Remember in the early '90s when there were dozens of garage outfits modifying Philips CD players? All they were doing was replacing the cheap op-amps in the analog stage with something better - either tubed or solid state. That made a *massive* difference in the sound - just as swapping out a cheap preamp with cheap op-amps and electrolytic coupling capacitors for a reference-grade unit with discrete parts (tube or solid-state) makes a massive difference in the sound of your system.
