I just recorded a buch of stuff using my Un-mod AT933s > PS-2 > AD-20 > JB3 over the weekend and the sound is great. It was up close at some really loud shit in a very small space (see my Duo Buggin pics in Rig Pictures). The mics didn't clip or distort at all that I could tell, but I was hitting the minimum gain of the AD-20 a little. It clipped with the gain turned all the way down, but only a tiny bit on percussion spikes. It's not audible, but I saw it in the JB3 levels and again in CE2k. I'm not too worried since that was one of the loudest shows I've ever taped and the mics performed very well.
If you want phantom power with mini XLRs and a preamp/ad all in one I'd look at the Core Sounds Mic 2496. If I had the money to spare I'd go that route for sure. I'll be interested to hear about what you come up with too. Good luck!
