What is so hard to believe? Physics hasn't changed, only our application of it.
IME, NOS DACs have a very organic presentation that is rather nice on simple music, but breaks up or washes out on complex passages. I prefer the native sample rates in a more modern (revealing) chip.
FWIW, the chip its self is but small portion of the sound of a D>A conversion. Transport clocking, output filters and output stage are just as important, if not more so.
