Qobuz is a CD quality streaming service similar to Tidal. A French company, it is widely available in Europe and elsewhere. Qobuz offers significantly different content than Tidal, no doubt due to different agreements with providers. Sonos offers Qobuz as a music option in Europe. I would like to suggest they simply turn it on in the US for those of us who subscribe to that excellent service.
Roon, the comprehensive metadata and player service that integrates with Tidal, internet radio and your owned library, would also be an excellent addition to Sonos. For me it would allow bringing together of my audiophile stereo system and my Sonos for a truly complete home wide streaming experience.
