CAFS--9vBB--Sony PCM-M10 Line-in.
I was actually comparing them to another pair of mics at an opening act I didn't care about, switching mic pairs from song to song. The CAFS sounded tinny to me, and I remember looking afterward at specs that confirmed the bass roll-off. I have a vague memory that the roll-off was under 100 Hz, which is a big loss for music.
But as I said, this was years ago and the capsules may have changed. I can't find CAFS specs now.
