Wow... I make a post, go out of town for a day, and come back to 50 responses. Thanks for all the great advice from everyone... I have already calibrated using an Avia disc, and just wasn't that pleased with the result. I'm sure it's purely operator error, as I am pretty new to the world of not-HTIB home theater. Thanks to the person who PMd me and offered to loan me their mic; I'm going to give it a shot, and if it doesn't help, then I'll just reset everything and start over with Avia & my ears, no harm no foul. Plus, I could probably use the experience... Thanks again to everyone!
