With Firmware 4.3 for Mu-so 2nd Generation, Mu-so Qb 2nd Generation, Mu-so Wood Edition, and Mu-so for Bentley Special Edition, owners of these wireless speaker systems will gain support for Tidal Connect.
If you stream music, you have likely heard of Tidal, the service that made its name offering lossless streaming before the other big-name streaming services caught on. What Tidal Connect does, is let you cast music directly to supported devices, in lossless high fidelity. According to Tidal, other streaming solutions will place limitations on the quality you can achieve, but Tidal Connect does not have quality limitations so if you play hi-res music, that's what you get.
Notably, this update is in addition to a previous update to Naim Uniti players, the upshot being that the entire current range of connected Naim products has this capability.
