Hi John,

There's a lot of good info on mics over at the Bose site. Here's a link to the wiki and if you scroll down you'll see several mics and the setting the owners use with them.

My personal fav is the Seinheisser e835, but the Audix OM5 seems to be hugely popular over there.

I'm sure you realize that with your tonematch, you don't need a pre at all.
Best of luck with your search.

Cheers
Jim
