Meridian have announced a new lossless format aimed at making hi-res music more compact for streaming purposes - MQA. 4.6Mbps drops to 1Mbps.

Is seems as though this can be carried inside a standard FLAC, WAV or ALAC
type container. No mention of who they are partnered with on the
content provider side, but it looks interesting.
The article at Stuff seems to suggest that a compatible device is
needed, but non-compatible devices will play the file at CD quality.
The "A" in MQA stands for authenticated. Which is a bit worrying, but if it is only used for streaming, I guess the ability to use the music across multiple devices is about apps not about portability of encrypted files.
