My LCD-2.1's left channel died, so I called Audeze up and got a RMA. They say I will be getting the newest drivers and rings (Maybe a entirely new pair). Either way I guess I'll get to hear what the difference between the 2.1 and 2.2s are. By the way, you couldn't ask for more courteous customer service. Fantastic to deal with.
