Most equalizers do not have sufficient control to correct the problems Bob mentioned -- their response bands are too broad, at fixed frequency and Q, affect phase, and consequently induce new distortions for every one they correct. He has an interesting thesis, and some evidence to back it up. I'm still waiting for a properly controlled, statistically significant study which shows that people can hear the difference between amps even without identical frequency response as measured at the speaker terminals -- anybody out there have a reference for me?
