Great post, Chris, thanks.
After the back and forth on CDM a couple weeks ago, I posted an
open-source class that uses passthrough for mp3, wav, aif, and m4a.
Forgot to post it here on the list.
In short, there's no need to transcode to m4a. (The trick is to use
the passthrough preset with the quicktime mov output file type then
grab the mdat atom out of the resulting .mov file)

Of course, as I note in that post, anyone with access to the 4.1 beta
may want to look carefully at the diffs before using
AVAssetExportSession for this purpose.

I've been able to convert AAC, MP3, and ALAC from my iPod library into PCM, with the caveat that you have to use AV Foundation to export each song to an .m4a before you can open it as an Audio File (and the MP3 and ALAC conversions are lossy and expensive).
