Personally, I'll cut the cost and run away...fix this time doesn't guarantee the drivers will be working after the 3-yr replacement warranty period. The cycle could be going forever!
I have LCD-3 that keeps having dead-driver issue, more than all my fingers can count. One time Audeze said due to corrosion so doesnt seem to relate the 'phones being used or not. So far, Audeze fixed for free and I'm in SoCal so not too much issue of sending in the 'phones. I'm not going to cough up $600+ to fix a problem that I know will keep happening. It sucks, it hurts, but gotta cut-n-run. I'm not going to get another Audeze 'phones again. The services are great and the sound is great, but can't trust the products...not gonna keep dumping money into a money pit.
