Yeah I cannot tell if the Bamboo is a fix for the cracking issue or not because they cover the cracked area with the new connector body. I suspect Bamboo to be more flexible than Rosewood, but I could not find the statistics for such things anywhere.
I find that there were not many complaints about the LCD-2, but the LCD-3 has a list of issues including a veiled sound, crackling, lack of soundstage, and other driver issues.
Looking at the charts I cannot justify paying x2 the cost for hardly any measurable differences:

I will admit that the biggest change is in the Harmonic Distortion curves.
Here they are separated.

To me these are significant differences, but I had a hard time distorting either pair. Distortion was not an issue with my setup. This is the reason I cannot justify the higher cost of the LCD-3. Add in the flat ribbon cable, the veil, and the driver issues and I really cannot justify it. I think the LCD-2 is still the most headphone per dollar and probably the best headphone period for the widest range of accurate listening experiences.
