That's a pretty big variance on budget. For $2000 you can get a very nice receiver with a full set of preouts for future amplification. I have a
Marantz SR6011 I bought from AC4L and it's pretty sweet. You could also look at
Denon's X4300H. Lots of features and pretty much anything you need. Either one of those 2 are fantastic receivers. If you want to stretch that budget to the max you can get something that may not need any additional amplification at all.
I'd stay away from Harman. By all accounts I've seen, they're not what they used to be. I would also use HDMI and connect everything to the receiver and let it do your source switching. I only run 1 HDMI to my tv from my receiver. Everything works beautifully.
*Edit: Yamaha makes very good receivers also. I like Denon and Marantz because they use Audyssey for room correction and I like how it works in my room. The SR6011 I linked also comes with a 3 year warranty. That was the big selling point for me. $899 is an excellent price for what it is.
