The new Marantz flagships and Model 30 have "Marantz Musical Mastering." This is a discrete DAC based off a DSP which does the digital filter, noise shaper, and resonator by Marantz's original algorithm. It performs digital audio processing such as dither. They actually name drop dCS, Mola Mola, and MSB as the handful of companies that don't use off the shelf DAC ICs.
