Martin Logan vs. Everything

I heard these playing a Roger Waters album at a show and they sounded amazing. Mostly. I noticed some odd effects best described as phasing –like the channels were reversed or holes in the frequency response. Could have been the setup. Either way, if you like them, that's all that matters. A home demo of alternatives is the only way you can really be sure. 

"Any better" is very subjective!  Over time our ears get used to the speakers we listen to.  More expensive definitely doesn't mean better 90% of the time.  Modern speakers are overpriced in my opinion.  Every now and then a gem pops up that is truly worth their price but not very often at all.  I know of a highly respected audio engineer that has been using Meyer Sound speakers all his life at live venues. Although Meyer sound is not considered "hi fi" equipment, but professional equipment, this engineer uses bookshelf Meyer Sound in his recording studio because he is used to the brand's/ designer's sound signature and not because he can't use better ones.  He's just used to their sound.  

I think there are people who like or get the electrostatic or planar sound and others who don't. If you really like or love that sound, don't worry about what others think or tell you. 

From a listener's perspective MLs often come out on top.

In terms of being able to ignore the room and provide life-sized imaging it's rare to find other speakers that do as well.  Perhaps the Sonus Faber Stradivari can compete there.

Where the MLs can lose points on is overall frequency response and dynamic range.  The SF Stradivari are the only speakers I know that can best them in both imaging and frequency).

It's quite possible once you get used to the ML's you really can't hear anything else as neutral, and that's fine, but it may also be hard for others to come and love the ML's for the same reason.
