Bah! Plenty for ribbons. If you need more gain, get it after. I had a singer last week , 2 feet back from a ribbon, RCA BA-2A preamp, and getting +24 dBm peaks. You just need an actual talented unfettered artist, or proper caveman hitting the drums. Etc. I frequently have ribbons into 40 dB preamps, with plenty of output level, sometimes even with a 20 dB pad.
