Be is not available widely as its a scarce resource. There is only once company which can make Be foils and they are found in speakers which are more than $3000. Also most expensive speakers which claim to have Be speakers the Be content is less than 0.6%.
psychoacoustic Be placebo is a topic of research of the person who has written "The Whole Truth About Beryllium Diaphragms."
Because any beryllium synthesized in stars is short-lived, it is a relatively rare element in both the universe and in the crust of the Earth.
The article is from 2009, and this is based on the content in loudspeaker compression driver diaphragms. It is very much outdated, and the weight and dimensions of an IEM driver are MUCH, MUCH lighter than the drivers they are talking about. .6% of a CD could easily make quite a few 50%+ Beryllium IEM drivers, which is still great.
Not even close. The Piston is light years better, and I still love the 8320.
Looks like Monoprice will be offering a Studio Monitor Headphone for $55 soon. At first glance, it looks like an ISK or Takstar OEM headphone.
Sony Hybrids, Complys, or dual biflanges. They tame the bass a bit and make it smoother. The stock tips are terrible.
