Anyone know if the LE XC have the latest drivers? My LE's warranty card says inspected 10/2015. My normal edition says inspected 01/2016. After prolonged listening I feel there is slight difference in sound because if there is anything it's subtle. Maybe it's in my head. It may be different wood density.
I contacted Audeze and here is there response to new 2016 drivers.
"We feel the current versions of our drivers offer a modest improvement in sonics but the differences are subtle and are probably not noticeable except in direct A/B comparisons. If you are interested, here's some information on some of the changes for our 2016 LCD driver revision:
-Reduced diaphragm thickness: Reduces driving mass for greater diaphragm response.
-Higher compliance: Lowers resonance for improved low frequency extension and bass definition.
-Optimized magnetic circuit: Creates more uniform magnetic flux distribution for a more uniform driving force, smooths frequency response, lowers distortion, with greater resolution and improved imaging.
-Improved diaphragm tensioning: A new system delivers better performance and improved consistency for less variation between units.
-Improved internal damping: Better, more controlled bass and a smoother overall frequency response.
-New voicing: Smooths the midrange response."
Any LCD-XC made after 01/25/2016 have the updated drivers. Unfortunately my limited edition XC has old drivers, and I think all LE XCs have the old drivers. I feel the sonic difference are audible but is very subtle.
Update:
I contacted Audeze, and they are nice enough to update my 2 week old limited edition XC drivers for FREE. Wow can't beat their support. This is likely determined case by case basis, but at least it's worth calling/emailing and ask.
