Best way to stream Itunes to receiver? (1 Viewer)

I'd like to get my itunes from my PC or even from my ipod for that matter played on my system located in another room on another floor. I have wireless networking setup in the house.

Looking for opinions on what is the best way to stream from my PC as that would seem to be the most convenient? I'd like to be able to scan or browse the library away from the PC as well.

I'm open to even getting a new receiver from Denon or Yamaha that have the Ipod dock option although I'm not sure that is the best solution?

Thanks in advance!!! T

PS- Currently using a Yamaha Rx-V2600 receiver.

Apple's Airport express will do just that. For under a hundred bucks.

Apple - AirPort Express

If you want more functionality, Apple TV will do the same for you.

XBOX 360 will do the trick too believe it or not.
And since the new upgrade, you can now stream movies from Netflix through the 360.
