Hey
A while ago, I bought the PA-2 as it was the smallest player for the Gym. Hey it even had AAC on the box. Couldn't find anything that AAC support for the PA-2 at the time, and there still isn't.
Although the hardware can do AAC, (or so it says) there is NOTHING that will download AAC to the device - no RioPort, no WMP NOTHING.
But... having downloaded Nero with AAC encoding, I encoded some tracks, choosing Export to ISO/AAC file, so I now had .AAC files and .MP4 files
Musicmatch (which I normally use to download) doesn't recognise AAC files, but I renamed the .AAC to .MP3 - add them to the playlist, download and Voila! AAC files, playing on my 'so called' AAC compatible player.
In the end - it's just a pain in the ass - just nice to know - it does exactly what it says on the tin. Still takes 12mins to transfer 60Mb of data though. Doh!
