The same Tom Martin who wrote the think piece that is the subject of your post has talked about the Mola Mola Tambaqui DAC in that context:
He points out that the Tambaqui DAC solves some important problems with digital distortion.
In my system it has a tonal balance and tonal density comparable to my previous R2R DAC (Yggdrasil LIM), but it sounds much cleaner and purer, in the highs and elsewhere, and also more natural (believable) and less synthetic than my R2R DAC. That DAC had already stood out as being more natural sounding than quite a bit of other digital, especially on physical CD playback.
The Tambaqui sounds more analog, also due to the lack of digital distortion (which Tom Martin addresses in above video).
