Integra DTC-9.8 Pre/Pro $1800

Has no real competition IMO, a very easy choice for a pre/pro. Decodes all nextgen codecs & has builtin Reon HQV video processing.
For 5.1 (IMO all that is really needed):
Parasound Model 5250 5x250 Power Amp $2500

But if you really want to make a killer 7.1 setup, buy one of these in addition dedicated for your mains which should be the biggest power draw:
Parasound Model 2250 2x250 Power Amp $1200

Has just a bit more balls than the 5ch amp, so great for big mains. If you are going to do 7.1 you might as well have a dedicated power amp for your mains.
Could also do Parasound Halo
A51/
A21 for amps but they are high priced and unnecessary IMO. Main gain is balanced inputs. But hey, if you are up for spending up to $7k maybe you want balanced inputs
So, total for 5.1 = $4300, total for 7.1 = $5500... MSRP of course, so it will be a bit cheaper. If you want to spend more, go for the A51/A21 combo instead (about $2k more).
