I've said several times that the K712 is darker than the Anniversary, and I thought that was the reason you disliked the Anniversary in the first place! So I'm not sure why you still think you'd prefer the K712 to the Anniversary??
I guess you'll have to try it for yourself one day, but I'm not sure you'd like it if you disliked the Anniversary...
BTW, I bought a HD650 last week and compared it directly the K712 and the latter had more low bass.
I'll repost my comparison from MLE's thread here...
BTW, I just picked up some HD650s to audition out of curiosity.
After trying them out last night, they're pretty decent, but they've mainly just reaffirmed my love of the K712s.
Comfort wise, I had kind of forgotten about dat' Sennheiser clamp. Granted this pair isn't that broken in, but still - it can be an issue. . I actually like the way it looks, and I like the lines and curves on Sennheisers full size headphones. I hear they chip paint off a lot though. The AKGs feel much loser and more flexible - I can twist and bend them around all over the place. On the HD650 the whole headphone feels very rigid and not very flexible at all, like a tight piece of plastic. The pads could stand to be a bit deeper. They're not as deep as on the PC360. I'm not a huge fan of how the headband padding fits me either. There's no padding at the very top of the head which feels a little weird. Sort of feels like the Audio Techinica wing system.
Sound wise, the HD650 signature is pretty good. Pretty balanced and with a clear a focus on the mids. That's the same thing I said for the MA900, and the HD650 signature is not too far from the MA900. The differences are the HD650 has more detail, more refinement, and a slightly more natural timbre.
Next to the X1, the HD650 sounds slightly more refined, more mid-rangey, and more intimate. They're also more boring (sorry :p). The HD650s are like a more buttoned-up version of the X1. The X1 is like a more open and fun-titled version of the HD650.
Next to the K712, it has less bass and less overall body. I hear some low bass roll off in the HD650, and the mid bass is weaker. The treble doesn't sound all that different between them. I don't notice a huge difference in air amounts. The lighter more midrangey signature makes the HD650 sound a little more "clear" in an immediate comparison (same as with the Q701), but I don't think they're necessarily more detailed. Mainly more forward and intimate with a mid-range focus. People always say the HD650 is great because it's nice and full sounding, but the K712 does all that better IMO. I still prefer the timbre on the K712. The K712 and HD650 take almost the same volume level on the amp, despite their different impedance.
As for the soundstage....it is on the intimate side :\ To be fair, I was warned about it. The HD650's imaging is actually pretty good (especially given the room it has to work with). The problem is the soundstage itself feels a little tightly compacted (at least for a full size open headphone). It sounds like someone is taking their hands and fighting to try and hold all the different sounds in tightly together to an extent. With the K712 it sounds like they give up and relax their hands to let the sounds spill out some. When I switch to the K712 it almost sounds like someone flipped some 3-D soundstage effect ON. The placement feels much more relaxed and open. The Fidelio X1 also reaches out farther to the left and right than the HD650. Again, the imaging on the HD650 is pretty good, and you could use it for gaming. It just could use more room to work with, and I personally need more soundstage room in a full-size open-headphone like this in order to live with it.

What I like about the HD650 is it has a nice balanced signature with lovely mids and good detail. The intimacy makes the mids very easy to hear. If you love mids and don't mind intimacy, the HD650 can be great. Unfortunately that intimacy is a bit of a deal breaker for me. I wouldn't reach for these when I can get the same performance from the K712 but with a more spacious and open sound. I prefer several things on the K712: It has more body, better low bass, a more natural timbre (IMO), larger instruments AND a larger more open soundstage (yes, both at the same time), and is more comfortable.
MA900s give you a similar signature with a more open sound than the HD650 but with a bit less refinement, less detail, and a bit less natural timbre. I've read how some people prefer the HD650 to the HD800, but I know that wouldn't be me. The HD800 has a delicious soundstage, while the HD650 soundstage leaves a slightly sour aftertaste in my mouth.
