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.
