I'm shopping for a HT system that will initially be 5.1, but I would eventually like to move up to 7.1. I'd decided on the 2802 but it looks like it might just be 6.1. Will the 2802 give me 7.1 and if so, will it be that same as what the 3802 has (other than the extra power of course)? The 3802 is out of my budget so I'd have to wait until the next line comes out so the prices on the 3802 will drop. The sub I'm looking at is a SVS PCi powered sub if that makes any difference.
