My musical tastes are wide and varied. I listen to it all, except cRap and Opera (but Amadeus is one of my fave movies). I don't want to used stands, so I haven't considered the M22's. The room is 13X23. My choice will between the M40, M50, and M60. What do you mean when you say, "Either speaker compared to the M60 becomes almost a non-issue for HT use"? I want to ensure that whatever I buy will not leave me wanting to upgrade too soon. If cost isn't the issue, will the M60 be the main choice. The sub will come in due time (near tax return time). Thanks for the reply.
