What is the point of 96khz?

Isn't 44.1khz enough for perfect 2-channel audio reproduction from nyquist theorem?  What is the point of higher frequency sampling?  Note this is a serious question, so I'm looking for real answers or white papers etc on the subject.

I can't provide white papers, but this discussion HAS come up many times on this forum. Search for discussions on DVD-A or SACD. The general consensus here is that 96kHz isn't needed, and it is just marketing BS to move us to new formats with better copy protection.

Listening tests have been inconclusive, since DVD-A and SACD sources are often mastered or mixed differently than redbook audio versions. Search for the discussion on Pink Floyd's DSoTM SACD release, in particular.

Higher sampling rates are useful to prevent aliasing during mastering steps, with certain digital effects.  Plus, you can trade off bandwidth for SNR using dithering, which can be useful in very quiet environements.

Why 24bit/48kHz/96kHz/, If 16bit/44.1kHz is good enough?

Higher sampling rates/bitrates might be useful to someone doing studio work, manipulating samples, altering pitch, filtering, performing DSP effects etc.  This could be useful for a DJ scenario as well, because it's possible that the sound would be much better when changing tempo vs. CD Quality.

For average consumers, there would be no audible difference, and it's just a selling feature so that consumers will accept limiting new formats with insane levels of copy restriction, annulment, and protection (C.R.A.P.)
