Yeah last night they sounded like 95% identical. Not a joke. I think maybe it was due to my apartment being kind of hot and the pads really soft and compressed. I also was using the O2+Modi which could have given a slight impression of more treble and a clearer sound.
The only difference I could remember was that maybe the mids were a bit fuller on the Anniversary. Smaller soundstage. A little less open and airy sounding, but still pretty good. I actually never heard the Annie sound that good before! My guess is that it's more due to the pads than the gear differences. The treble on the O2 sounds a bit different than on the Micro, but still measuring the same I imagine.
When doing A/B comparisons between the O2 and Micro Amp it was kind of tough to hear any differences. Micro seems to have a bit more body to the sound (barely audible) and is smoother. O2 seems a tad clearer somehow, but everything sounds a little more forward, but that's impossible! I'd probably failed a blind test between the O2 and Micro unless it was a track i've heard a hundred times. The O2 is really impressive so far. Especially since it can hold up very well to my Micro amp. The E9 and Magni never could.
The bass on the Micro does seem to be a little better but that's probably my imagination..
I also noticed that some detail seems more "in your face" and much easier to spot on the O2. I guess for those that want the clearest sound possible from their Annie, try the O2+Modi!
EDIT: So IMO it seems the Annie sounds best to me when the pads are really warm, soft and very well compressed. I can't wait to see how bad they sound in winter when stored in a cold room. Maybe they're not as bad as memory foam pillows.
It really is interesting how much harder those pads feel when you have left them sitting all day.
