also the Core Sound Mic2496 in an option. that'll provide phantom power and will allow you to record 24 bit. a lot of people won't recommend Core Sound products, because of some questionable business practices by Len (the owner of Core Sound). that said, my one dealing with Len (a long time ago) was positive, and I've have some nice sounding recordings made with the Mic2496. for reference, it's the same size as the Denecka AD-20.
