The Nyquist theorem never stated anything about accuracy, only that to
reproduce any given frequency, it must be at least half the sample rate.
If you sampled a 10khz sine wave at 20khz, it would become a square wave -
certainly NOT accurate. Most filtration in CD players would wind up
rounding the edges off anyway, but it's still not accurate - as compared
to the source.

I hear people state this so often, but the higher sampling rate has
nothing to do with a desire to hear higher frequencies, but rather to keep
the higher frequency signals more true to the original.
