I've spent a lot of time reading posts about these mics and decided to go with the GT33 for a couple of different reasons.
First, I'm not a fan of the extra power supply for each mic.
Second, I think somewhere Dan Richards posted up about of all the instrument condensers he looked at in the famous shot from The Listening Sessions. I can't find a picture of all the mics right now but there were more in one location than anywhere on the planet at one time. And, Dan made the statement that out of all those great mics that was thinking about getting a pair of the GT33.
My Guitar Center dude got on the computer today and tracked me down a pair of the GT33 so I'll be getting them in about 10 days.
