If the use-case is simply for playing audio files, RAIDZ2 would be OK.
Recording multiple channels into Ardour or a similar DAW would likely be
problematic on RAIDZ2, though.

Absolutely!  Sizing the ZFS appliance to a workload was always a huge part
of the configuration.  It was always interesting to try and help engineers
explain to managers why their 200TB storage appliance only had less than
half that amount of storage as usable space.
