Too bad the Airport Express doesn't stream audio through it's USB port. There are some good USB DAC's that I'd like to try (Scott Nixon USBTD). I don't have one yet and am looking at an Entech Number Cruncher 205.2 (made in 1999) because it has a toslink ouput.
Nonetheless, I am new to this and am quite...stoked..on the convenience. Even the sound out of the analog AirEx is pretty good compared to just plugging your computer straight in.
Don't know if you've changed speakers, but did you find the Totem's a little "bright" (harsh). I had the Totem mites (much cheaper speakers), and they were new, imaging was great but fatiguing. Although, I wonder, if I had a DAC?
Also how is the sound through the toslink? There's all this stuff on the internet about SPDIF and jitter. I don't even know if you can hear this stuff.
There is a delay with the AirEX, so supposedly, it's no good for video. However, with Airfoil and VLC, you can change the settings on VLC so that it syncs up with the audio out of AirEx. Use your mini as a torrent/divx media centre. I tried it, works perfect. Go to (or read the following if the site is no longer around).

1. Launch VLC.
2. Open the Preferences page from the VLC menu on the menu bar.
3. Tick the Advanced check box in the bottom-left corner of the window.
4. Under the Audio page (the page that comes up first when you open the Preferences), set the Audio desyncronization compensation value to -2700 (note the negative). *
5. Drop down the Input/Codecs menu on the left-hand side of the Preferences window, then drop down the Access Modules menu. Select the File item. Set the Caching Value in ms to 3000.
6. Quit VLC.
7. Launch AirFoil. Select VLC from the Source drop-down list at the bottom of the window. Click the Transmit button (the one with the speaker icon on it).
8. VLC should automatically launch. When it does, open the movie you wish to watch and enjoy your syncronised, high-quality audio.
Any other new changes to your Mac system? I have an Intel Core2Duo Macbook. Love it. It's hard to find a material possession, like my first snowboard, that has brought me so much... joy.. but this laptop has.
Nice system. And it took me till late 2007 to figure it out.
