JM Labs Beryllium

I agree with the comments that anyone interested in the improvements of the new JMlabs line compared to the old should DEFINITELY go and audition them for themselves.

As far as Berylium goes, its effects are far more devastating than silicosis. Be is one of the more toxic substances around. For many years, material scientists/chemists have wavered on whether the myriad improvements(and they are real improvements) outweigh the risks in processing the material.

However, the danger IS IN PROCESSING berylium. It is the dust that can enter a person. Once in a stable state, those around should have no worries AT ALL. Sure, there are some real headbangers around here, but unless you are playing your music so loud that the speakers are being pulverized, and Be dust is forming a cloud in your listening room, you can rest easy.

I wonder why no one talk about Diapason III, this are
French speaker,very musical as a whole, of course
they are not perfect.

Thanks for your responses. Actually I could still afford a used Mezzo Utopia at 5-6K but was told that the Beryllium is much better. Yeah right and the price for a brand new pair is a killer too.

I've just recently upgraded my amp from Classe CAP-100(excellent integrated) to CAM-200 but still considering what speaker will be replacing my old B&W CDM 1SE. Anyway guess I'll still be using these and wait until late next year hoping to see a pair of Novas Utopia Be in the used market. Tough chance!

Most probably I'll be getting the MEzzo Utopia next year since I won't be able to afford the new Beryllium range of speakers. How I wish I could have the Novas in my room!

Cheers.

I would like to comment on the response to Beryllium as respiratory toxin. Beryliosis is caused by inhalation of the beryllium particles into the airway. In order for beryllium to go into aerosol form, you have to essentially have to heat the tweeter to it's melting point. Since the melting point of heavy metals are fairly high this would not usually in normal operating conditions of a speaker. Beryllium is toxic, however. It would not be a good idea to lick the tweeter and put yourself at risk for beryllium toxicity. Fortunately, in my 11 year career as pulmonologist, I have yet to see a case of Berylliosis.

I heard the next generation will be dampened with depleted uranium, have very special diamond matrix tweeters, and a special nitroglycerin reserve to reach those ultimate dynamic peaks! Or maybe not. It's just a rumor.
