I'm the first person to say that I want 192 kHz sampling for all my digital audio sources, or a minimum a 384 kHz master with a 96 kHz mix for distribution.

But the tweeter only needs to go to the edge of human hearing.

Extra information in the digital signal is not to extend the upper frequency response, but to limit aliasing in the audible range.

Considering most every CD and movie soundtrack is mixed at 48 kHz the only information above 20 kHz is noise-shaping by the DAC.
