I've got to agree. I LOVE my M60's and they are on the factory outlet for $990cdn right now. Or the much-heralded M22 plus HSU VTF-2 combo has a high WAF, if you like speakers on stands.
Since you are used to the fullness of a 3-way monitor, I don't think you'd readily accept going back now. You'll love the M60. Really. They're wonderful.
The form-factor of the M60's surprised me a little; they are deeper than I envisioned. Not a negative, but just note and believe the dimensions listed on the page.
