Multiplying DAC used for audio, any experience?

[HAYK]

I have great envy to design with the high precision 16bit MDAC LTC1595.
This DAC comes with 2 grades, A, with +/-1LSB max INL or for much cheaper, gradeB +/-2LSB.
I can use the reference input as bi-polar sign bit with adjustable voltage to serve as volume and use only the 15 bits to make the grade B as precise as A.
The only encouraging example I found is the Schiit Audio Yggdrasil

Any DIY exemple?
Any con I should be aware of?

I’ve seen such a use case of a multiplying DAC for volume control here on DIYA some time ago, I think this was from member Sonnya
