About 90% done with the MA900 review... I'll probably finish tomorrow.

Glad to see your not letting subjectivity get in the way
Hmmm...about the treble. I heard the Anniversaries and X1 having more extension on either end - the MA900's upper treble and sub bass were both less present to me. I heard the others as being more fleshed out on both ends while the MA900s freq. range was bit more compressed. (BTW, that lesser extension, along with the forward mids, was why I was saying they sounded slightly "n" shaped.)
Greater extension doesn't mean more treble though. I remember the MA900s occasionally sounding a little sharp, but I didn't dig to deep to find out what was causing it.
I don't think the X1s sounded veiled next to the MA900s though.
I notice that sharpness as well on the MA900. The MA900 seems to have some grain in the upper midrange and treble.
I had this with the Signature DJ. While being so much more better than the Pro 900 and a bassier Sig Pro the bass somehow overpowered me in the end in some regions across its spectrum. It was pretty good for games albeit the smaller soundstage than the Fostex but that bass annoyed me very soon. Sold it today.
While TH-900 can slam very hard as well the bass is fast, very detailed and has a "shape". It's never annoying.
Same for the HD 800 except it slams less but has a very detailed bass section that extends very deep.
