Avia calibration disk works well but I've ony used it for my video setup. For the audio calibration, I've used the auto setup that the Denon has built in. It seems like its pretty good, but some swear by the spl meters. I guess all the different sound fields the Denon is capable of using is confusing. I do have a 7.1 speaker set up. I don't know, just interested in your experience or anyone elses for that matter.

Vegas...Hmmm sound like a great trip in Jan/Feb, gettin a little toasty yet?
