I got a basic idea of the sound of both the MS907 and the BMC-2’s in the live recording gallery, which is a really nice feature of this website. As an aside, if everyone who put up samples made a point of listing what equipment they were using, it would be even better IMO. Both mics sound good to me, but since you can adjust stereo imaging with the BMC-2’s, but can’t improve the bass response of the MS907, I’m leaning towards the BMC’s for my expected uses. If I were doing video cam stuff, I expect the MS907 would be a better choice, much more convenient. S/N ratios in this price range seem to be about 58-61dB, so I expect I’d have to maximize input volume with a mic preamp to do nature recording, as you suggested A440. If it’s not too much trouble, I’d enjoy hearing a bluegrass recording King Ghidora. I wish we had a country music radio station here on Long Island, NY and we could get GAC on cable for the Grand Ole Opry, but that’s another story.. Thanks, MIchael
