JM Labs Beryllium

I too heard the JM labs Be's (I think they were Alto or Nova's) at my local dealer here in Austin (Sound mind audio, who are very nice/knowledeable guys to dreal with). They were powered by Boulder amps........ I think the front end was Accuphase. They sounded REALLY GOOD, great detail, very musical. They are out of my budget so I didn't check model too closely, sorry.

I agree with the above post and would think that you need to audition them in your room........ they are big and expensive.

I too was listening to one of the beryllium series at my local dealer recently. I found myself thinking as much about potential health hazards as I did about music. Beryllium is nasty stuff that can cause a lung disease similar to silicosis.

I'm no hazardous materials expert, but I wonder if there are any risks associated with exposure to the beryllium in the speakers?

I have the Mezzo`s I have listened to both the Alto`s and Nova`s with CJ tube`s. I must admit they both sounded very nice. But must also admit they did not sound 10K better a good used pair of mezzo`s are going for 5.8 to 5K. As Ghostrider45 has mentioned about hazardous material each of the 3 seperate encloser`s are lead lined on the Grand Utopia`s, Utopia`s, amd Mezzo`s maybe JM Labs next model will have a plutonium woofer.(Ha Ha).

I listened (obviously not what you're interested in but good FWIW) to the Mico Be for a very extended listening experience. Up to that time, it was the best damn monitor speaker I have ever heard. That is until I decided on Harmonic Precision's Caravelle. The Micros need a sub, but what monitor doesn't? Well, the Caravelle doesn't. Then, the fella at Singer, took me (upon my request) to listen to the Altos. Hooked up to some very serious electronics. Though, I didn't listen long, I loved the sound, but still thought the speakers overpriced (the Micros as well) and after listening to the Micros for a long time, did not find the soundstage as deep. Andy, the Singer in Singer Audio, is, also, very interested in listening to the Caravelles ab'd, believe it or not, against the Altos. Sould be interesting. This is down the road a bit, but hopefully will happen. Will keep you posted. peace, warren

Jazzdude your right about the new Utopias having a much better damped cabinet making it more rigid.
But I disagree with on the Sound of the Older Utopias.
My friend has the JM Lab Mezzo Utopias on a Conrad Johnson 2500A Amp, Krell KBL preamp. These speakers sound so natural and transparent. The Bass is so perfect. There the best speakers I ever heard in my life. I'm curious to hear the new Utopias line. I heard the new Beryllium tweeter takes awhile for it to break in.
