No, the M3ti does not have the sibilance issue, but it's not quite as smooth and uncolored as the M22.
As to seeing an improvement with larger floorstanding speakers like the M80 or M60, it really depends on how big your room is and how loud you like your music.
In my 20 x 13 x 9 ft room, I hear no advantage of the M80s, which I also have, over the M22ti and the EP500 sub.
The one limitation of the M22 is its dynamic limits. The M60 or M80 would play cleaner at high volume in a bigger room than the M22s.
As to Mojo, he'll have to do double-blind tests first; then he might modify his judgments. And so far as recommending a speaker he's never heard, that's just crazzzeee!
