Anyone who has not visited the
AMT website recently should take a look. In addition to more info about the mics, there is now a section with audio clips. There is an interesting interview with the mics designer Marty Paglione and musical clips by Christian McBride, David Ruffo,Steve Rodby tand others that are well worth listening to.
One other thing I found interesting was in the technical specs for the S25B. It shows the phantom power as 12-52v, not 9v like the battery. I'm not quite sure if that implies anything as far as using it without the little black box, but maybe some of the electronic guru's around here can delve into that.
