One thing not mentioned is that Sonos One supports 24bit from Qobuz, but Play:1 apparently doesn't.
It's noted on Sonos site that "Older products may only support up to CD lossless quality for all tracks", which apparently refers to Play:1 and Play:3 despite being S2 compatible. https://support.sonos.com/s/article/1782?language=en_US Of course whether you can hear the difference is a different matter.
