I would be interessted in your thoughs about the wunder cm50 as well, Alan. Also if you find other solution's for Decca that are interessting.
My thoughs on omnis for orchestra, as far as I have experience...:
Although I mostly do Jazz Recordings, I have to record Orchestras from time to time, mostly for Soundtracks. I have experience's with Original M50, M150, and DPA 4006 on the Three.
With the M50 it depends extremly in what shape they are and what services have been done to them. While I have been extremly pleased with them in a session in Abbey Road I have been disapointed with them in another Studio. As it shows later , they have been serviced by neumann, and have been transitorized!
With the M150 I had a session recently in Munich and I was really not disappointed. Fine Mics. They provided the typical large, warm but also silky sound I want for Filmmusic.
The DPA 4006 are not really providing the sound I am looking for, when I record an orchestra for a Film-Score. Too clasical sounding maybe?
