My LCD-3 Review
So largely in isolation - and after taking a pair apart, all the way down to the raw components - I concluded that because the diaphragm was rigidly edge-clamped and relatively stiff and heavy (in Mylar-and-electrical-traces terms, that is) there was mechanical energy entering the frame structures and releasing through relatively small and stiff pads via bone conduction to the ears.
And it’s possible Audeze reached the same conclusion, because in my opinion the most important addition to the LCD-2 Rev 2 was the much larger and softer pads. I believe these act to mechanically decouple the frames from the head while maintaining a good seal.
Thanks for posting this review, very nicely done and quite the counterpoint. I had a hard time with my original, early-model rev.1, evidently because of the stiff pad problem. The worst part was the headaches that I would get around my temples when I wore eyeglasses with them. The bone conduction problem that you mentioned is also very interesting.
But just to nitpick I wanted to point out that just before the rash of rev.1 driver failures that preceded the introduction of the rev.2, Audeze changed the pads on the rev.1 to the same ones that are being used on the rev.2. I have never had any of the comfort problems due to the stiff pads with my current rev.1, which I ordered at the very end of last year. It seems that I was lucky enough to get the rev.1 with all of the improvements of the rev.2 sans the new driver material and optional leather headband. I believe my current LCD-2 to be part of the only batch of rev.1 to come with the new rev.2 pads that didn't also have the defective drivers.
