I'm curious what you other computer audio guys are using in your computer audio rigs. I figured it would be neat to get a list of rigs going: What platform are you on (Win/Mac/Other), what software are you running, and what's your audio gear?
iMac OSX Lion
iTunes w/Amarra HiFi (runs on top of iTunes, replaces iTunes with much better sound engine)
Musical Fidelity V-Link
Schiit Calhalla tube amp feeding Sennheiser HD600 headphones
Woo Audio WA6 tube amp feeing Sennheiser HD700
Swan M200MkIII Speakers
I also own Pure Music, Decibel, Audirvana, and BitPerfect as alternatives to Amarra, but prefer Amarra over all of them. There rumor of JRiver coming to Mac as well...
