Hi,
> I have little idea what's in it.
Funny, I know exactly what's inside and I could even draw you a circuit.
It is a straightforward LC filter and a pretty good idea at that.
Of course, squashing that noise inside the SMPS and doing it all across the audio range, rather than only catching the high frequencies is an even better idea.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
