I debated this issue longer than anyone, I think. But, I finally took that final step and upgraded to the M60s after reading Tom Andry's review of the Vassallo series speakers where he compares his M22s with the M60s. This sentence which I am quoting from the review, "the m22’s give you the bad news straight; the m60’s at least pat you on the shoulder while they deliver the news," sums up perfectly what I believe is similar, but yet different between them.
