Hi Mnyb. Yeah, it's hard to get a sense of what the limit of the ADC is
but I agree that the Transporter XLR is hitting the limits already... In
comparison to Stereophile's AP measurements, I suspect I'm maybe missing
the bottom most 3-4dB of what the Transporter is capable of.

As for the E-MU 0404USB, here are a few numbers in RCA loopback mode -
not bad as a DAC itself! Compared with Transporter XLR:
14503

The jitter is really good for the E-MU also:
14500

With digital silence playing, here's what the noise floor looks like:
14501
Noise floor zoomed into 0-100Hz range - notice essentially no 60Hz
pollution:
14502

For such an inexpensive unit, I'm impressed! As I said before, doing
these tests have been quite educational and will certainly let me
objectively compare performance of every line-level device including
cable changes I add to my system in the future. IMO this is invaluable
and way better than listening to "audiophile reviewers".

BTW: When Sean Adams said AES/EBU was inferior to SPDIF, was this in
reference to the standard in general or specifically to the
Transporter's implementation? Wondering why this would be given clearly
the balanced cable's superior noise rejection ability; at worse I would
have thought they'd be equivalent.
