You don't see people doing that with headphones like the HD650. They aren't called HD650 Rev.2 because of the silver screen, or the K701 Rev. 2 which has 8 bumps on the headband instead of seven, with an obvious sonic difference. Its old, and its new. Yet, they are just called what they are.
Seems people are quick to wanna add a revision number just to planar magnetics for some stupid reason.
