I have upgrade fever after upgrading to a Pioneer 643 64" TV and a Panasonic XP30 DVD player in the last week. My Yamaha Rxv-995 is working fine. Should I replace it? If so with what? I have Norh 4.0 speakers and an Adire Dharman sub. After the cash spent this week I'm hurting, but I feel my receiver is now the weak link. Any thoughts? I'm thinking in the $850 or so out the door price. I'd really like something that can handle switching different video sources.
