It accepts music from the home network via LAN or WLAN with the protocols UPnP, Airplay or Roon RAAT up to 24 bit and 96 kHz clock. It can access Spotify Connect via the Internet and decode Bluetooth signals with aptX. As a true meridian, it of course decodes MQA files - however only up to the first level of 96 kHz clock rate, because the complete unfolding of the MQA file is reserved for the "MQA renderer" in a suitable D/A converter. This could be, for example, a meridian loudspeaker connected via Speaker Link. It's a shame that Meridian doesn't have an integrated tidal access - that would be the ideal source for MQA files. The 210 Streamer is operated and set up via the "Meridian Controller" app for iOS and Android. The compact device is just over 20 cm wide and is now available for 1100 Euro.
