So here's what I've got in my studio:

Mic Cabinet:
(2) Earthworks TC30k
(1) Earthworks SR-69
(2) BLUE Dragonfly
(2) AKG D112
(2) AKG C3000
(2) Shure SM57
(1) Shure SM58

Crane Song Spider
Mackie HD824
1.8 gHz P4 DAW
Cubase SX
Tons of plugins
Also a ton of high end bass, drum, and guitar gear

What would you get next? I've been thinking about a large diaphragm tube mic, maybe a royer. Would something like a Manley voxbox be worth while?
