hi to all DAC sifu here..
plan to get an Aego M on my next upgrade.
i'm currently using Audiotrak Prodigy 7.1 HiFi..
my question is: does the worth to add another DAC [let's say ZERO DAC]??

from (1) Audiotrak Prodigy 7.1 HiFi -> Aego M
to (2) Audiotrak Prodigy 7.1 HiFi -> Zero DAC -> Aego M

or should i consider to sell the audiotrak and use the onboard optical connection instead?
(3) OnBoard -> Zero DAC -> Aego M

any difference between (2) and (3)??
