I haven't heard Harbeth speakers but have had a pair of Raven II's for about a year and have been very pleased with them. They are articulate, respond well to upstream components, seem to roll with room placement limitations, and are beautifully handcrafted heirloom pieces. Christopher is very helpful and worth talking to if you are interested in learning more about his speakers.
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.
