There is some very good silicone around, ESS being one, only for some implementors of these sophisticated devices to somehow manage to undo the the in-built ability/spec. by bad engineering.
To get red-book CD quality right should be at the forefront of many makers of digital end-products rather than trying to blind consumers with boutique chips/ingredients which may not perform any better than an implementation of an older version of silicone (done correctly) once they had their grubby little fingers in it.
I am purely talking about measurements here. There are enough examples of the above to make you/me wonder.
Done right, these powerful new chips can do things on paper older versions can't but how much these are really of benefit in the real world (also called listening to music ... remember that?) I have no idea.
Some of the possible dynamic ranges quoted would probably make ears quite literally bleed if a system was capable of resolving it. Pointless to have? Probably not, low noise, high dynamic range, low jitter, super-low distortion etc etc (many of which are compromised by the implementation of the chips rather than the silicone itself) are probably worth having but there is probably always enough potential down-stream ... think amplification, speakers ... to make the benefits of such high functioning DAC's more hypothetical than practical.
Then there's the old chestnut of just because something measures better does it sound any better? There are many examples of deliberately introducing distortion etc into the signal path via valves or otherwise and thus perhaps making use of some of the abilities of these super chips but not others.
