I agree with Bob_reynolds. Amp design just doesn't change that much unless you want to go to something next generation like a stack of NuForce 9.2s which would be awesome.
I would also question the notion that its worth staying with one manufacturer. Very few companies do a good job with both - especially if you want some serious watts.
Check out Anthem which makes both and is highly regarded - I had their 7 channel amp and its very good. I am personally not a B&K fan but they know the territory and lots of people love them. Cary has a great reputation too - don't know much about their pres but there is no doubt they build killer amps.
Integra and Marantz offer excellent pres with all the tricks - definitely get something with Audyssey built in EQ - phenomenal in a HT setting. They make fine amps too but I would not be afraid to mix and match
Right now I am running an Integra 9.8 with a Butler and it is very sweet.
I'll bet the Integra 9.9 would make you Sunfire sing too.
