AirTunes alternatives?

I am looking for an alternative to the AirPort Express that I used for several years to be able to play my iTunes music collection on my home stereo. I want to make this change so that I can also stream Pandora to my home stereo in addition to music from my iTunes library.

I have a pretty old Denon receiver that I am very attached to so I’ll need something that can result in an RCA input for the receiver.

Have you look at Airfoil to enable other apps to stream to the Airport Express? Free to try, $25 to buy.
