Totem is pricey for what you get. PSB makes good speakers, but I thing you need to go at least to a mid line speaker before you approach Axiom quality of sound. I have not listened to Aperions.
As far as the Axiom line, they all have the same neutral sound. The M80's have a slight advantage in the midrange and treble over the M60 or M22. Not a huge difference mind you.
Once you add a sub to the M22m it sounds almost identical to the M60. I had a hard time telling the difference in a direct comparison where I could flip back and forth with a speaker selector switch.
So, it really depends what you want to fit into your room.
