On an impulse, bought the airport express.
It took a while to get set up right, but it seems to work fine. It’s slightly annoying how its rather sensitive to wireless network interference. I wish the audio buffer was a bit larger, enough to handle 1-second dips in signal strenght or something.
Also, it doesn’t come with SPDIF cables.. which while understandable, slightly annoying, since it has the less common round optical SPDIF plug instead of the square one. I guess this means I get to go find a high-end music equipment store in sf.
