Agreed. Oppo supports only Tidal. You'd have to use a streamer feeding into the Oppo (and thus using the Oppo as a pre- and DAC).
What quality level are you using for Tidal? Their HiFi and Masters options make a huge difference in quality over their default -- and definitely over what Spotify has to offer.
