Foster has two bio-cellulose drivers as far as I can tell.
The 40mm neodymium magnet driver with composite bio-cellulose diaphragm in:
CAL!, Denon 1001, Emu walnut
The 50mm neodymium magnet driver with composite bio-cellulose diaphragm in:
Denon AH-D5000, Fostex TH610, TH900. THX00 and in Emu-Teak.
I always see comparisons between the same 50mm or 40mm driver but I was wondering what is the main difference in sound clarity and quality between these two drivers. The price is 10x as much, but is there actually a big difference in the quality? I cannot find any reviews or comparisons but I'm hopeful some of you have heard both.
