I heard the Ravens at the 2018 CAF and was seriously unimpressed. I don't know if they've undergone development since then. They were in a LTA room driven by one of LTA's integrated. (I speak as a H 40.2 owner.)
Any Harbeth users hear Fern and Roby Ravens?
I'm trying to get s sense for the difference between the sound of thee two brands. I have M30.1s and am intrigued by the Raven and especially the Raven II because the limited space I have requires me to move the speakers in and out for listening.
I like my M30s but always trying to improve.
