Music Quality: Spotify on Sonos Connect vs Mac Output from Tidal?

[gswpitt]

I currently have a Sonos Connect and that streams music at 44.1 Khz 16 bit to my Receiver with a Built-in DAC.

I am testing a Trial Version of Tidal and the Audio Midi Settings on the Mac display 96Khz 2 ch 32-bit integer when playing streaming music at a higher resolution.

Can anyone clarify if the Mac/Tidal output is significantly better than through the Sonos Connect (with Spotify and iPad)? Is this better than CD quality?

Thanks in advance.
