The Aux input goes through a very crappy analog mixer (a CM9780).

This is a good idea in general, but on the Xonars, the line input
bypasses the CMI9780 (this is why there is no hardware volume control),
so you get better quality by using line-in and then doing amplification
on the digital recording.

A signal-to-noise ratio of 118 dB on the line input.  You can do *lots*
of digital amplification before you come near the noise level of a vinyl
recording.  On the aux input, you get at most 95 dB if you're lucky and
don't use gain.
