Sony has a treat in store for Music Unlimited subscribing audiophiles: you can now stream music in high quality 320kpbs AAC audio.
Using the service's web, Android, Walkman and PS3 apps, Sony says you can now enable "pristine" high fidelity playback. The entire catalogue offers the 320kpbs AAC option provided by Omnifone, the company that powers Sony's music library.
If you don't want to be stuck with tedious average audio, you'll have to turn the 320kbps streaming option on in Music Unlimited's settings menu.

Before today's boost, Music Unlimited used only the HE-AAC v2 codec at 48kbps. So if you aren't running the Android, web or PS3 apps, you'll still be stuck with 48kbps which is crappy at best, but Sony promises a boost to this 'normal' level is coming later this year; it will be going up to 64kpbs HE-AAC v2.
It doesn't look as though the high quality option is available on Sony's smart Bravia TVs nor through its iOS app yet, although Sony promises it will be adding it to other devices "later".
Music Unlimited is Sony's in-house answer to Spotify - the illustrious multi-platform service already offers 320kpbs AAC playback but its quality consistency is questionable at best.
