If you use a 31 band EQ on the sound going to the monitors isn't that going to alter the phase in each frequency band? So what you hear will have a different phase response than what is being recorded. Maybe an FIR EQ would be better? I believe that's why the mini-DSP boxes are popular, you can EQ without introducing phase changes.
