Take a look at https://listening-test.coresv.net/results.htm.If I am not mistaken Opus is an update to the ogg vorbis format which is and improved open source version of mp3. I use have alot of ogg encoded tracks and it provides good compression and better sound quality than mp3. Not sure how much more you will get from Opus vs ogg which of course the M0 does support. I don't have any devices that support Opus but I would love to know if there are any real differences in terms of compression and sound quality with Opus vs ogg?
This page is pretty interesting too:http://opus-codec.org/comparison/
