I use an E-MU 1212M that I am very happy with. This soundcard also has an EXCELLENT (for a sound card) DAC, which I also use for output to my computer speakers. My standard music path is:
FLAC -> Foobar2000 -> E-MU 1212M -> glass toslink cable -> Benchmark DAC1 -> Zu Varial IC -> Singlepower MPX3 -> Sennheiser HD650 headphones w/ Zu Mobius cable.
