I feel that my room benefitted from running Audyssey, but I've not tried setting it up with an SPL meter or done much in the way of room treatments(thick rug over hardwood exception). People generally either love or hate Audyssey but I'd agree with what Doc says, give it a try and see if you like it.... it should get you in the ballpark.

Half of communication is listening. You can't listen with your mouth.
