I've updated both my work and travel set ups.
Macbook Pro (Fidelia/iTunes, Audio Hijack Pro, Redline Monitor Crossfeed and EQ)
Yulong D100 Dac (under the computer)
Bottlehead Crack OTL tube amplifier (to the left)
Sennheiser HD600/Beyerdynamic 880 600 Ohm/Denon D2000/Grado 225i
Portable Rig is still the iPod Classic, but I'm using a Ray Samuels P51 amp, and the Beyerdynamic DT1350.
