Honestly I think Alan should read up on Audyssey, it is a totally different technology than past years setup routines in receivers, and blows Trinnov out of the water if you read the reviews by many. Speaking highly of the THX founder on other issues, but not this creation, is not fair. It made a HUGE difference for my room and made my Axiom great speakers sound even better, as it factors in the rooms characteristics in the time/space domain.
When I cycle between it off/on it is night and day better.
