I ended up replacing my original AirPort Express with an Apple TV 2 that I had laying around collected dust. The receiver I use for my Hi-Fi setup has HDMI-in, so I use that, but the Apple TV 2 also has an optical out. It has been rock solid where the Airport Express was having lots of issues with dropped audio.That's the one I have. Wish I could claim it was still reliable but using it is an exercise in frustration.
