I don’t think Spotify is leading the way in viewing and selecting the genre of “classical”. Hopes were better fulfilled with other providers (Qobuz, Idagio & Co.).
But there are also satisfied classical customers at Apple, Tidal, Deezer, Amazon, Google or Spotify, although it is clear that only Tidal and Deezer played in the Hi-Res league.
When the catalogs and technology are converted to Hi-Res without compromise, other providers may claim the same. Some are nimble with words, but don’t follow up with action for months or years.
In the presentation, Roon sets the standards and integrates two Hi-Res music services at once. The friend of classical music does not miss out either and can select many subgenres or styles in “Classical”. I assume the good handling is known.
However, you can also get suggestions for searching and filtering very well with Spotify. I present this better in a separate thread using the example of “Classical”, which also always plays a prominent role here.
