Got the K612s first impressions are VERY positive [though I will probably buy the K702 pads just for the sake of it].
These are very early impressions, while still waiting for my M-Stage to arrive [so relatively underamped out of my Clip+]
The sound signature is great for me, detail retrieval is amazing, bass are very tight, mids are very good, imaging is excellent, soundstage is big enough, highs are good too [though admittedly a bit sibilant yet].
I imagine the amp will solve the few things that are lacking now, but even out of my Clip+ it beets the MA900 [IMO] in almost everything except for air [:/] and raw soundstage size [Though I imagine it will improve with the Matrix].
The sound is very good out of the box too [though burn-in usually has little effect to me], comfort is pretty great too [zero padding on the headband initially concerned me, but it turned out to be a non-issue, as they are really lightweight, they seemed heavier from the pics, but they are almost as light as the MA900, much lighter than the X1s ], though the Angled K7XX pads might be a bit better [I'll buy them later]
Very happy with the decision [thanks a lot kman!], saved a buck and am very happy :]
Impressions/comparisons will come when the amp is here, but I am really, really impressed. I am only said it took me so long to try the AKG brand, but am glad I finally did.
Also, these are made in China [well designed and engineered in Austria, but made in China :D]
I also had no idea AKG is a subsidiary of HARMAN, good to know :P
