The dampening factor effects Sennheisers to the greatest degree of the common audiophile brands, AKGs and various other headphones are not really effected much. On Orthos dampening factor doesn't matter at all since the frequency vs impedance on them is ruler flat. Amp quality and power is what matters the most.
I am curious about the HE-400i, I'm planning on it as my next major headphone purchase. I got the K712 and I find it better than the K612 albeit different, but the difference in refinement becomes more apparent the more I use them, although I need to listen to both on a better amp extensively to come to a more solid conclusion on how they compare. I am planning on getting the Project Ember in the not too distant future, I plan on updating my review after I get the amp, or I may just make a new review comparing the K612 and the K712.
