Hey Danz -
My two cents (and that's about all it's worth!) -
Here's my thinking - something has to amplify the signal coming out of the mics (even for loud shows). You can either have the h320 do the amplification the way you do now, or have something else do the amplification. I think the question is whether the Church Audio preamp is better (cleaner) than the preamp in the h320. I've never heard the preamp in the h320, but I expect the CA preamp is MUCH better. I do know the CA preamp is MUCH better than the preamp in the MicroTrack, and the MicroTrack is specifically designed for recording, whereas the h320 is not. So, at any given level of amplification, I expect the h320 is going to add more noise than the CA preamp. In addition to noise, there's the whole issue of "color", or how faithfully the preamp reproduces the exact frequency and dynamic range of the source input. Again I'll bet that the CA preamp reproduces the inout signal better than the h320.
As long as my assumption about h320 vs. CA preamp quality holds true, I think the rest follows logically. Of course, sometimes I'm an idiot so use any suggestions with caution...<grin>
Good luck!
Mike
