I got this advice from an old pro that won several world finals,
"If you need 30 bands of equalization, your doing something wrong"
Now that would not apply if your going for absolute flat response (which doesnt sound good to your ears) So i would go with a parameteric EQ, I loved my Alpine H600 processor, time delay and a 5 band parameteric EQ in one. It is no longet in production, but silimar models are available, and its not too far out of the price range of the EQT's by Audio Control or PPI's 30 band EQ. The H600 also had an adjustable Q for even better control of each band.
