I just noticed that Raumfeld announcement was from April 2015. The article said that a US launch for their speakers was planned for 1 Sep. Their US web site still says, "coming Fall 2015".

On the other hand, this article from Aug. 25, 2015 says that Bluesound has MQA support on its roadmap.

Future plans: BlueSound’s roadmap includes:
--adoption of Meridian’s MQA (Master Quality Authenticated) audio technology. BlueSound products will likely be in the first wave of MQA-equipped products, which will likely be available this year, the company said. For streaming and downloading music, MQA files deliver higher performance sound quality in smaller files compared to today’s high-resolution music files. Music from analog, PCM and DSD masters can be MQA-encoded and placed inside any lossless-audio “container” such as FLAC, ALAC or WAV and can be played back in lower resolution on non-MQA devices.
