I own the Moabs and Magnepan 3.7's. The Moabs have a very rich involving sound but the fact that they are cheaply made, poorly damped, box speakers also shows up in the way they sound. The Magnepan's are a little less involving but technically I would say they are better if you have the space to properly position them. I like them both for different reasons but if you held a gun to my head I would choose the Maggies first. The planar sound coupled with a pair of subwoofers is incredible. If you like tubes the Maggies aren't really an option without a much bigger budget. Ultimately, it is apples and oranges and a very personal preference. I have never listened to the Revels or any other high end speakers except for the Spatial Audio X3's which I suspect are better than either the Maggies or Moabs but again different sounds for different tastes.
