Do you have any local brick and mortar hifi shops in your area? It sounds like you're trying to spend a boat load of money without ever listening to anything. You need to get out there and spend some time listening to some stuff. You're totally setting yourself up for failure and auditioning gear is so much fun.
Does your wife enjoy listening to music? I'm sure your kids do but it's not unreasonable that some people just don't like listening to music. I had a boss that told me he didn't like music. No big deal but it might help the forum guide you.
If you don't have any future upgrade plans, you should probably consider Al's suggestion of an integrated amp. There's some amazing choices out there for integrated amps. I get my newest one next week and its the best I've heard so far with my speakers. That's the deal though. I've heard it with my speakers and I loved it. That's when you break out the plastic or the checkbook.
