I have been on the fence until the 7700 was shipping. I am about to order a 7700/990 combo and also Axiom speakers, including their M80ti towers. Thus, I will have large mains and "small" surrounds. Will this be a problem for direct inputs? I use these now with my "cheap" Sony receiver, and I assume the audio will be best with the 5.1 inputs rather than either coax or optical digital cables.

As I understand it, I should be able to run a 2.1 set up for audio only, if I desire, with anything below 40hz sent to my HSU subwoofer. For home theater, SACD or DVD-A I will be running 7.1 and will want anything lower than 80 HZ sent to the subwoofer. Is this a problem with different sized speakers, or is everyong complaining for issues that won't affect me?

Please let me know before I order.
