hola all,
 well to answer youre question about "noise"
when i built my studio box, noise was a big concern, especially from
using a LCD screen, they are noisy little buggers, so as i put the
parts together, i used the shielding off of old video cables from
monitors and hoped to avoid ever finding out if there was noise
inducted on the sound card....
in the past, i had heard clock signals, through the sound, and didnt
want a repeat on a studio setup
  the card is manufactured, with ground layers sandwiched between the
other layers. no real exotic shielding....however i make use of some
shielding, (i used a box from the crt video board, of a old monitor) to
isolate the inverter, and also the touchscreen-to-serial board) also
the backplane is grounded to the hilt.
  bit-rate affects "studio quality" sound engineering and not much
else...when you spend all kinds of money, to hear a pin drop....IE>
bi-amped studio monitors, korg keyboard, and a digital mixing deck
you will notice a slight difference...richer sounds
now, you are right in assuming that the difference between 44.1 and
96khz is more noticable.
  now for mp3 ripping and listening...it is sub-CD so, it would not
make a difference what it is playing through.
