good point indeed.
i'm wondering how the SNR of the preamp relates to the digital side
of it, i.e., is noise floor of the preamp an issue in the de-emphasis
(+LF, -HF) "better" than the bit resolution of the digital side.
one issue may be that when we look at a pre-emp curve, it looks like
there's no bass and loads of treble. curious if anyone knows what the
actual *energy* measurements are, and wondering if they are in fact,
relatively equal across the spectrum (since music is not).
