If you add all the rev.1 owners that had to honestly answer that they don't know because they haven't heard the rev.2 yet to the ones that prefer the rev.1 it's about even. Big if though.

I think I'm leaning towards the 2nd revision. I just dont think they'd revise it unless they were improving something.
The LCD2's are open right? Would someone be disappointed in the strength of the bass compared to an ultrasone pro 900?
Well now, that's a moot point. It's been suggested, by me among others, that Audeze went looking for new materials after the several failures of a few months back and came up with what is now the rev2, not by design but by accident. Alternatively it could be suggested, given the original wording on the website, that they tweaked the rev1 to be more in line with other company's flagships--IOW, not because they thought it sounded better but because they considered the sound more commercial.
I plump for the first theory myself, as it makes complete sense. It seems to me just too much of a coincidence that they come up a new version so soon after having a number of component failures.
FYI...Audeze has said so much (dated July 3, 2011):
"Why change it suddenly ?
A couple of reasons. We have developed new diaphragm material that offered several benefits over the existing material. We decided to pass along the improvements to customers. The issues we had with some older stock gave us the impetus to move to the new diaphragm quicker than expected."
That said, my R1s were from last September....long before the issues with the last run of the R1 drivers.
Could it be this:
"Advanced thin film:
Wisdom Audio is one of the first companies to abandon PET (Mylar™) in favor of more advanced materials that have superior dynamic and temperature
characteristics. Of these, the polyimide family of polymers is the most promising, some of which can handle temperatures in excess of 725°F (385°C) —
far in excess of what even the most advanced adhesives could hope to withstand. Fortunately, this is also a temperature range unlikely to be experienced
by any planar magnetic driver, except perhaps in the most demanding professional applications."
From what I understand, the diaphragm can be permanently deformed perhaps by too much long excursion or from heat.
The heat is generated by current passing through the aluminum deposit on the diaphragm which is its voice coil.
I doubt the heat would be anywhere close to approaching that. For dynamic flex applications, the thinner material, the more mechanical excursions (by orders of magnitude).

It can if there's too much current. The deposit is like traces on a pcb board.
