Quite frankly, I have never heard of this company and based on my experience, taking the difference in the money to upgrade your speakers or improving your room acoustically would have a significantly greater impact than anything related to internal electronic changes. I would be concerned about the warranty and what about firmware updates? Are you sure they sell in to Canada because "authorized" Onkyo resellers in the US are NOT allowed to do so. As a result, since it is a Pre-Pro and might need a firmware update down the road and IF these guys aren't authorized dealers, you are going to be out of luck.
As far as the Marantz products are concerned, you might have checked with Amazon.com. since they deal with countless retailers in the US and generally have them in stock including the 7005.
