The mids are MA900 all day, every day compared to the X1, and the X1 wins on sparkle vs both the MA900 and Annie, though it can also be more fatiguing than both. This is why I say the MA900 makes a great alternative to those who can't afford the Annie. It has similar strengths overall. The Annie is overall fuller sounding, while the MA900 is fuller and smoother than the X1 overall (other than the bass being fuller on the X1).
