Hello to all!. I´m new in this Forum, this is my first post. I do recordings of classical music and ethnic music. This ethnic´s recordings sometimes are field recordings, without AC power. I´m in the task of upgrading my gear. I´ve recently purchased a matched pair of microphones: Schoeps CMC6-xt, cardioids. I think it is a good start. Now I´m investigating about a 2 channel pre for these microphones. I could buy a Millennia HV-3B pre, but for ethnic recordings I would need a battery powered pre. Wich battery powered pre do you think offers the best sound quality ? And how near or how far do you think is it from a Millennia HV-3B? Thank you very much, your knowledge will be greatly appreciated. Oak.
