Update: I just spent a week with ATC SCM19 v2s in the house and I can say that for me, they aren't even close to the 30.1s. Very sterile, way more "pro" sounding than I expected. Really no sense of musicians playing in a room with fingers on instruments.
So I'm pretty sure a lateral type move to a more dynamic speaker isn't going to work after trying the ATCs and the SF. Hard to replace the things I can't do without that the 30.1s give in spades.
