There is one way to make sure this is software or hardware based. Use a minidsp with Dirac software. Not 100% reliable, but should at least give slightly different results if the root cause is software. If you plot the results in a graph the difference should be visible.
I did tried a foobar xover plug-in which is dead simple (Linguitz Riley 24db @40Hz -3dbFS/Linguitz Riley 12db @40Hz -1dbFS) and the result was identical with the internal software.
I also did Multitone Analyzer's intersample overload tests (along with the gazillion others) just to make sure.
Seems that it's tied to hardware.
(note that my measurements were on the analog outputs,so much-much worst than the digital ones shown here,you can safely make the analogy from Amir's 114db SINAD vs 130+db SINAD here with pure digital )
