Just got off the phone with audeze support. They are working on fill-in the orders starting today. Is there any difference between 2015 Bamboo drivers and 2016. Has there been any changes in the version after fazor.? Lost track of them.
Fazor drivers were changed/updated in Dec 2015 IIRC. So if the 2015 Bamboo was made in Dec 2015 it would have the latest drivers, if made earlier then the original Fazor drivers.
