Not even analytical, a good "discrete" R2R dac is even more detailed, yet it’s airier with much more musical sense and far more body to the mids, and then there’s the unmatched bounce and slam to the music they have as well.Sorry, but this is complete rubbish.
Some of the best dacs out there use ESS chips - Ayre, Brinkmann, Lumin, Mytek.
I've owned a "good" R2R dac - a Metrum Pavane - and the Ayre QX5, Mytek Manhattan II and Lumin X1 with their ESS chips walk all over it. And, yes, I've owned all of them.
The idea that R2R dacs have "unmatched bounce" or are more detailed is just ridiculous. The current generation of ESS chips are outstanding which is why they are used in many very high end dacs.
