The Bluesound Vault has an ethernet port for connecting directly to the router. But the only way to get the Tidal flac is through the Tida Connect App and not the BluOS app. Theres no way to directly connect my android phone or pc to the Vault, so it needs to be wireless.
Hopefully, mspot is correct and Bluesound will correct this and Tidal Connect flac will be integrated into the BluOS like the Tidal mqa is.
In the meantime, I can keep both Qobuz and Tidal.
