Bluesound also offers gapless playback by default for all supported file music types.

MQA (Master Quality Authenticated): Bluesound is the first wireless multiroom audio system to support MQA (Master Quality Authenticated). MQA is a revolutionary end-to-end technology that captures and delivers master quality audio in a file that's small enough to stream or download. Bluesound worked closely with MQA to implement technology inside each Bluesound component to ensure the listener will hear MQA encoded music and streams exactly like the source and the way the artist intended you to hear it when it was approved in the studio.
