Here's my 2 cents. I've had amps and avrs with damping factor specs from 50 to over 1100. I can't say it's been a game changer for me or a crucial spec. More and more I just want good synergy with the particular speakers I'm working with, and the best way to hear if an amp controls your speakers well is to hook it up, or audition it somehow.
That said, if an amp manufacturer is paying attention to the damping factor performance of their products, they are probably really anal about how their products sound, and that is a good thing.
