It is true that Yamaha experimented with Beryllium in the late 70's. The difference between the Yamaha drivers and that of the Utopia and the Electra Be's is not the material however the application of the material. Yamaha used vapor deposition which is a poor use (or process) of the material. Vapor deposition is the spraying of Beryllium (in this case) onto a copper backing. This tends to make the drivers very heavy which defeats the purpose. JMlabs was the first manufacturer to develop a pure Beryllium diaphram. the fact that it is pure or solid is what makes the difference. I would disagree with David on the one fact of "this is nothing new" is way off base.
JM Labs Electra 937Be vs.Diva Utopia Be vs. Mezzo
Just got back from the audio shop this afternoon and had a fairly quick audition of the Electra 937. Very impressed I was. I was hoping to do an A/B comparison with the Diva, but for a variety of reasons was unable to do so. Perhaps will have a chance later.
I've now checked out the 907 and 927 Be, the first of which I liked a lot and the second of which I thought was disappointing. But the 937 is a whole different matter.
What I'd like to know is if others have made these comparisons as well and what were the impressions. Also how do the 937 and the Diva compare with the older Mezzo Utopia? If you had a choice, which would be the best choice and why? I had a very, very brief audition with the Mezzos a month or so ago, and liked them, but I didn't have a chance at that point for a full check with my own music. I'm still pretty blown away by the beryllium tweeter, which is just amazing with my musical tastes. Could someone also explain in more basic terms some of the technological distinctions between these three speakers? Thanks in advance.
