Blue Coast Music, a good source of high resolution recordings, have some free downloads of the same track in multiple formats for system comparison and testing.
The recordings are in DSD11.2, DSD5.6, FLAC96/24 and WAV 44.1.
You have to register and will get their regular emails as a result but the download is free. It's a 1.6Gb zip file so takes a while.
