I love my new 5790, but so far I've not configured its equalization, balance, etc. I prefer to run my system as flat as possible. I don't understand from the manual what the Optimizer does. The manual implies that it's very important to run it, but I'm wondering if I don't need to. Questions: * What does the Optimizer do to the tonal balance and equalization? I don't want the bass to seem boosted artificially. * We have speakers in two rooms. The second room (B Speakers on Zone 2) will always be just a 2-ch stereo setup. Is the Optimizer going to reconfigure those even if the microphone is in the room for Zone 1? * Finally, if we don't like the results of running the Optimizer, how tough is it to undo the reconfiguration?
