I record either classical music(from soloists to Chamber Quartets, to full on symphony/choir performances). Or acoustic music ( bluegrass groups, Gospel Quartets, jazz bands,)This is all done on location. I use schoeps CMC6/Mk4/mk2S, Gefell M930s, an AKG C426b, and Neumann u87s. I have two channels of DAV BG1, and two channels of Mytek Stereo 192 converters..I want to keep adding to eventually have 8 channels or so..SOOO. mY next question is, which preamp should I add next??I want some variation, different flavors, but I need them all to be fast and transparent, given the nature of the material that I record. I was suggested these: Millennia HV-3C Lavry 4496-18 Crane Song FLAMINGO GML 8302 Can someone offer up advice/real world experience or other suggestions ?? Thank you much.
