Long story short, I went from multiple headphone rigs into one (okay, two if you count the living room rig) speaker rig. Also, finally made the jump to computer-as-a-source camp.
The current rig is as follows -
iMac -> Apogee Duet -> ModWright SWL 9.0SE -> McIntosh MC2100 -> Eminent Technology LFT-8b
