In Reply to: What improvement can be expected with NOS DAC upgrades? posted by chuck55 on November 15, 2023 at 19:45:18:
Current DACs offering NOS mode are generally R2R or Multi-Bit DACs. The stated goal of these designs is a more analog or smoother sound.I believe all Delta Sigma based DACs apply over sampling to all incoming signals.
R2R/Multi-bit DACs don't try to become "more Delta Sigma" their entire approach is to sound LESS Delta Sigma-like. Not as harsh, bright fatiguing.
The truth is, the bad rap about harshness with Delta Sigma designs probably lays more with a designer's poor implementation of the input and analog output stages of the DAC and less about the kind of chip used for the digital to audio conversion.
