In true reality just look up on line 20 bits is the Actual true bits you can get ,
anything else are guesstimates higher bit rates , mojo audio for-example
explaines this well. R2R are a bit softer and good for a lot of music but not all
i use the older mastering standard the Multibit chipset which were are laser trimmed resistors on one big dac chip, like the Bricasti M3 I use
they use the Analog devises 1955 dac chips , all linear power supplies ,and filtering, power regulation ,very well thought out.That being said which I may buy
is their upper M1, and M1SE ,and higher stil M21,which has the Multibit, and R2R setup as well as differential DSD which is in all their dacs , please dedicated streamer board option which is excellent ,and 2 less wires.
