I take it that you have compared your external DAC with the
Transporter's analogue output and prefer the DAC? You mention that you
connect the DAC to the power amp via XLR, so of course to do a fair
comparison you need to use the TP's balanced outputs. And make sure
that the comparison is level-matched.

The reason I ask this is that the TP's own DAC is extremely good, and
I'm surprised you find any need to use an external DAC. Out of
curiosity, what is the external DAC?

There's an implication in one of your other posts that you're using the
TP's volume control at a fairly low setting. If this is the case, then
the SNR degradation that will result could overwhelm any minor
differences between the TP's DAC and the external one. I think you need
to make sure you get the gain staging right (with appropriate passive
attenuation) and operate with the TP's volume control at a reasonably
high setting before you can come to any sensible conclusions regarding
the relative merits of the DACs.
