If you are aware of the fact that your measurement methods (if any)

Do you really believe your own measurements ? If noise seems to
increase from -110 to -54 dB for sample rates above 128k, doesn't
that trigger even a hint of a suspicion that something could be
really wrong with the way you measure this ? No ? Nothing ? If not,
you shouldn't waste your time doing measurements of any kind - it
really requires a different attitude.

In the analog world, increasing bandwidth while everything else
is fixed will increase thermal noise power. Noise density will
remain the same, and that's the only thing that matters.

In the digital world, increasing the sample rate while keeping the
number of bits the same means the same quantisation noise power
will be spread over a larger BW, and noise density will go down.

If you measure anything else then either your measurement is bogus
or the equipment you're testing is broken.

Some of your remarks on the audio world in general may be to the
point, and I could even agree with some of them, but this talk
about noise is complete nonsense.
