Spotify Web Player vs Desktop Client: Music Quality. The current generation of music lovers is susceptible to the quality of music they listen to. Most people can tell the difference in music quality when using the two option, and others will not even notice it. Usually, the Spotify web player offers a lower bitrate compare to the desktop client. Along with our desktop, mobile, and tablet apps, you can play Spotify from the comfort of your browser on our web player. You can access the entire Spotify catalog and use many of the same features offered by our app, including: Search for artists, albums, tracks, and playlists. Browse our Featured section, New Releases, and Genres & Moods. Go back and open the Spotify app or website. Find the music that you wish to record and start streaming or playing it. If you want to record the music from Spotify itself, open your account to play the track that you want. Once again, be back in the iMusic app as the music plays in Spotify.
Spotify App Vs Browser
very enjoyable improvement. Even non-Masters tracks on Tidal sound significantly better. Currently, almost all tracks on Tidal at the HiFi tier are 1411kbps (non-Masters) and still the Spotify desktop app caps out at 320kbps.Spotify has been streaming 1411kbps for most tracks through their browser player in Chrome and only then I notice little difference between Spotify and Tidal HiFi. The Masters tracks still are noticeably better than the Spotify on Chrome app playing at 1411kbps.
There is an upside to streaming from the Spotify Chrome app for 1411kbps which doesn't incur extra cost but this is all functionality Spotify is not advertising. The downsides are this only currently works in the US (IIRC) and navigation in the Chrome Browser app is very limited compared to the desktop app.

I'm very surprised you were not able to notice a difference with such a great stack as the HD800s + Mojo and suspect it was something else in the chain limiting the potential. I suggest giving even just Spotify direct in the Chrome webapp a try again if not Tidal and ensure you have the chain configured properly.
