To get back on track:-

I'll take higher dynamic range and lower noise preamps rather than chasing =
the megapixels, erm I mean high sample rates.  And while were at it microph=
ones to match. -

Roll on the days we have enough dynamic range for mic emulation built into =
the recorder, learning EQ, mics that indicate their parameters when plugged=
 into a recorder - theres far more to consider than the analog domain alone=
. What if your mic indicated its maximum measured frequency (and a whole ho=
st of other parameters, sensitivity, snr etc) and the recorder was capable =
of adjusting the bandwidth to capture using (that) mic ? - Thinking about t=
hat I dread the thought of messages such as "Are you sure you want to captu=
re 192 Khz? I can only manage 44.1 Khz, Abort or Retry? (Y/N)"

Point being, roll on digital mics, digital headphone systems, transfer norm=
alization functions that pass between devices to ensure correct reproductio=
n. The audio equivalent of color management profiles. - Oh and all that sho=
uld happen transparently to the user.

Might be time for me to write a paper to the AES. But generally a photocopi=
er is smarter than me.

Lots to think about, so little time.
