Daniel, I didn't catch your initial message. Why do
you want to do D/A. I would maintain digital all the
way unless I've got some external analog gear that is
very high quality.

Do you know what type of power is used in digital

it's a mixture with constant to the analog circuits
and filtered for the digital.
I've never noticed any electrical related noise in my
computer but then I don't have any analog in that
system so there probably wouldn't be any. Is this
assumption consistent with your understanding of the
problem?
I don't know much about these issue but I'm curious
because my system will need analog i/o added. In fact,
I don't know if my terminology of filtered and
constant power is correct. Probably not.

Over the top of all of these points, I think you
want to be pretty
careful choosing your D/A. They do sound
different.
So the choice is between:
- an internal DAC that may be of indifferent quality
and pick up
noise from the PC's internal electrical
environment. - an external DAC that will be electrically isolated
from the PC and
will have nice clean power but may have clock
jitter problems.
