The Sony Walkman I'm currently using only supports AAC as the best compressed format I've known.
Before I became a low end audiophile I've been purchasing songs through bandcamp at AAC. All of them produced around 290~335 kbps for download.
I wasn't aware what FLAC was so I didn't choose that as an option. Now I always buy the discography albums for my music, and Foobar2000 has an encoding option to convert my songs to AAC 500kbps.
Is there a big notable difference between 320kbps and 500kbps with Nero's AAC format?
I'm using a home/semi-portable combo rig of an A900X, FiiO E07K and Sony Walkman E474
