Sad. You can't hear much above 10 K; why do you care about 24?

You can buy a credible MP3 player for $20 that'll run circles around your
POS Nakamichi.

1) One cares about whether one can get 24KHz reproduction out of a tape
machine (or any other reproducer) beause the flat response curve at the high
end actually affects the sound at lower frequencies (the characteristics of
musical instruments are that many carry large numbers of harmonics, which,
even if you cannot hear the harmonic itself, would change the intrinsic
sound were they not there at all)

2) There is NO mp3 player that can as accurately reproduce a complex audio
waveform as well as a high end cassette machine. I don't care how many
samples you take of a complex waveform with an ADC/DAC system, the resultant
playback waveform will never represent the original analog waveform as well
as a high end analog device. Even a simple 1000 Hz sine wave will not come
out as a pure sine wave after digital conversion, it will be a series of
stepped square waves. You may not be able to tell the difference with your
ear, as long as there are enough of those little steps, but that's not the
point. The point is, it will not "run circles around" a high end analog
device.
