I am currently on the fence between M60 and M22 as well as Ascend and Dynaudio bookshelf spkrs. I listened to a lot of high end speakers and found that most towers tend to get muddled or boomy compared to a lot of bookshelf spkrs. I demoed these with jazz and acoustic CDs mostly to really be able to pinpoint the clarity factor.

Can anyone elaborate what the proper "space" is for the M60. I sit about 10 feet from the main speakers which are about 5 feet apart and 10" from the wall. In speaking with a guy at Axiom he strongly recommended the M60 but it is my understanding that these are much more position sensitive than a smaller speaker.
