no problem, you can run Phantom power trough dynamic mics, won't hurt them,
but make sure you don't connect a guitar or bass to a channel provided with phantom....or...BOOOOOHOOOOOO
i only put my Sm57's on my snare, top and bottom,
but i tried to mess with a RODE nt3 .... the result wasn't really what i wanted,
i had alot more color, tone, sounded brighter and more clear,
but loud, and i picked up too much sound from the kick and other instruments.... so i'm real happy with my SM57's....
i think its more interesting to put one extra mike on the bottom of your snare instead of puttin one condenser on it,
but thats just my 2 cents of course !
cheers
