Ok, but for now i don't have a preamp, i will elect the option B...only i have to decide if go to onstage or in front of stage (closed as possible) , basically because i don't know if the band agree with an onstage recording, maybe too invasive...shaggy your advice sound good, i'll try to make.
Searching for onstage recording i can learn that i have to stay far from drums, but best an AB config with those dpa's or din or other with cards...i know that the best is experiment myself, but i would like to hear some experiences voices.
