Can you be specific about Sonos and libraries. Ignoring, for the moment, the screwed up app.
I’m using a third party app, and find it adequate.
With SONOS I think it’s difficult to separate app and library. It’s a system. When you use a third-party app, like I do as well, you don’t use the SONOS system any longer. You basically turn the SONOS components into stand-alone, DLNA- or AirPlay-capable active speakers.
Sonos developed a new search mechanism a few years ago. It was fast, versatile and did not work with local libraries. It queried the servers of the streaming services and ignored local libraries. In their old app at least they had an outdated search mechanism for local files, which is not available in the new app anymore. Like in, not at all, no search.
SONOS introduced Hi-Res support for certain streaming services, but not for local libraries. I suppose they assumed that local libraries consist of ripped CDs only.
The SONOS browsing experience hasn't been good for ages. Only streaming service users can work around browsing by using Search. Library users are stuck with scrolling through single columns of text, e.g. album titles, with thumbnail pictures attached to them. Nothing like double columns of artwork tiles with text underneath, on smartphones, or walls of tiles, on tablets, exists. SONOS even wastes the display space of a tablet, which is ridiculous.
There’s not even an alphabet column on the side of the screen anymore to let you shortcut scrolling vast libraries by selecting a letter.
Filtering options are very sparse when compared to other solutions, e.g. Minimserver. Say you’re looking for a song of Classical music, by a certain composer, performed by a particular artist. Without a search option you may begin by selecting “Song” and scroll until you’re blue in the face as you never get to select further filters.
I mean, why could streamers like WiiM, Cambridge audio, Eversolo etc. even become a thing? SONOS could have dominated the “Amp and speakers” segment as well as the “Just add speakers” market with their PORT streamer and AMP streaming amplifier, if they had shown some attention to detail.
While they sort this out I’m happy with the sophisticated filtering options provided by Minimserver in combination with DLNA apps. And the SONOS Smartspeakers sound as good as ever.
