The D1 arrived today.  I installed it, built and booted a kernel with 
the Xonar driver selected, and I'm pretty much blown away by the low 
latency.  It works just fine with 16 F/P, 2 P/B, 192khz.  This 
translates to 0.167ms latency.  Which is way lower than what I actually 
need and probably means a solid performance at 64FP/2PB/48khz/2.67ms 
(the settings I actually use).

Awesome work on those drivers, Clemens! :-)
