Hello to all.
I would like to ask your opinion.
I have read around that it is possible to replace the diaphragm of JBL compression CDs with beryllium truextent materion.
what results are obtained and how are they compared with the new RADIAN, BMS, 18sound CDs or other famous brands? costs?
a comparison with EV N / DYM 1 would be very interesting. it has been done ?
bye thank you
