"AK4191EQ and AK4498EQ split the traditional DAC's digital filtering & delta sigma modulation and analog parts to reduce the interference between the digital and analog parts. The general idea is similar to removing the current-voltage conversion with the AK4499EQ. The more scattered the better, moderately reduce the degree of integration to reduce signal interference. As for the indicator, it is inconvenient to directly compare with the AK4499EQ because it is split into two parts.
While conventional DACs use a single chip to convert signals from digital to analog, new products split the conversion process between the AK4191 delta-sigma modulator and the AK4498 DAC. This innovative approach has resulted in an improvement in sound quality that is easily perceptible while listening to music."
Not much of a fan of the marketing blurb

I read about it at this diyaudio thread:

These new chips supposedly are not targeted for manufacturing until Q2 2021
