Just one thing to say to this:
A "line" level audio signal is about +-0.5V ... If you have a 16-bit
soundcard the lowest voltage difference which you could produce on the
"line"-line :) is about 1V / 65535 = 0.0153mV ... So I don't understand
why to buy a supra-all-featuring-xx-bit soundcard because in such a noisy
environment like a PC you have noise voltages on every kind of wire which
are a LOT more than 0.0153mv !!!

experiment:
Take a piece of wire, make a small coil (a few windings would do it .. 4
or so), put it into your pc, attach a oscilloscope or a RMS meter to it,
look !

I think you wouldn't even have to make a coil.

As I heard on a Analog Devices seminar it hasn't much sense to make D/A
converters for more than 16-bit because at least the 2 LSB's will just
consist of noise.
