JM Labs Beryllium


Have anybody heard of the Alto Utopia Be or Nova Utopia Be? Are they any better than the superseded range of Mezzo Utopia and Utopia speakers?

Any idea whether any of these JM Labs speakers will sound good with Classe CAM-200? Actually I've got B&W CDM 9NT on my mind as they are cheap, but after 2nd thought I might stretch my budget further by getting one of these classy French speakers. The Utopia is definitely out of my budget but I would like to hear some opinions on how do the above speakers compare.

Thank you.

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.
