Not directly related to your question, but I am curious about your pro calibration comment. An Audyssey calibration is quite different than getting a pro calibration for your flat panel or projector, which normally gets calibrated and then left alone.
As you refine your listening area for best sound by adding new equipment, moving existing equipment around, adding room treatments, etc., you will find that a new calibration will be required more often than you might think. If by "pro calibration" you mean an expert coming in and doing it for you, that will be an expensive route to take. If you mean that you are going to purchase the Audyssey Pro Installer Kit and do repeated calibrations yourself, that will be less expensive in the long run. Or you can just continue using the consumer Audyssey calibration in your new AVR--it will provide excellent results at no additional expense.
If you are not familiar with the Pro Kit, there is a nice FAQ in this post: http://www.avsforum.com/t/1346723/the-audyssey-pro-installer-kit-thread-faq-in-post-1#post_20676480
Just my thoughts...
