JM Labs Beryllium

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.

classeguy - Forgot to mention. Before you go spending money be sure to audition at least a few of the Kharma lineup.

Well,Ladies and Gentlemen.Let me categorically state the JM Lab Alto Be is the best speaker I have ever heard and I bought a pair based on the new direction that JM Labs has taken.Of course with any speaker that has a very detailed tweeter, it is best to use either valves or state of the art solid state amps of the highest caliber.I have just found that amp from Chapter Audio of England.I previously had the Italian Graaf GM 100,a otl 100 watt tube amp.There is no comparison.It does everything one of the best tube amps I have owned and betters it in every way.Kudos to Ryan at Canadian Hi-Fi for showing me nirvana and bliss can exit in solid state.I also use my 2 channel set-up with a Panasonic 50" plasma.Good luck to all and happy listening.I truely believe the best system is the one you enjoy.Jim

Alto $15000.00 / Nova $30000.00. Whoa nellie, thats a whole lot of money compared to the $2600.00 B & W CDM-9NT. Just one Utopia center channel speaker cost more than two pairs of CDMs!

I have the 9s, they are mightily compentent in their price range. Seriously you would be better off comparing the Signature line by B & W, or at least a Nautilus. Although even the N801 is less than half the price of the Novas.

I have heard the BE Altos. They are a fantastic speaker. Better than the CDMs? Absolutely, and at that price, they darned well better be.
