Qobuz vs Airplay

I’m tracking for wireless connection to device processing and amplifying the signal to the speakers there is

Airplay, 

Chromecast

And UPNP(?)

For wired— Ethernet cable if not also USB cable 

Apple Music highest res is 44 kHz regardless of transmission medium 

Qobuz and Tidal highest res is up to 192 depending on the file and only if transmitted wirelessly via Chromecast, UPNP, or cable.  Highest “Airplay” wireless transmission caps out at 44 kHz. 
 

Do I have that somewhat right?

Apple Music highest res is 24-bit/192Hz. 

Airplay is limited to CD quality (16/44) last I knew.  According to ChatGPT, it is not limited to 320kbps, fwiw.  Regardless, you can’t get what you’re paying for out of Qobuz or any high-res service.  And its playback isn’t perfect. Furthermore, your phone is the player, which is problematic for many reasons and I suspect the phone may introduce degradation of its own.

I believe Tidal has caught up to Qobuz for quality since Tidal ditched MQA.

I have a Marantz Model 40n and I love it.  It has Tidal Connect and Qobuz Connect, so it will play those services at full resolution, and it connects to them directly itself - your phone is just the controller, not the player. 

@sextantcv4 Marantz is part of the Denon HEOS ecosystem, so you can add that to your list.  With my 40n I’ve got a high (enough) end class A/B amp for my main listening and small Denon Home speakers around the house for whole-home audio.  I feel this is superior to Sonos and Airplay.

With B&W 606 S2 mains my setup is perfectly adequate for my aging ears.

Yeah. Arcam tells me I have to control it and through Chromecast or UNDP To gain above 44 on Qobuz or Tidal.   I can check back on what they say about Apple Music   My impression was Apple Music was limited to 44 but I see someone said otherwise

Apple Music is high res, but like Tidal and I think Qobuz, their library ranges from 16/44 to 24/192.

Honestly I have to really try hard to hear the difference between 16/44 and anything higher, and 16/44 is certainly sufficient.  I grew my audiophile ears on CDs, so that's my baseline.  I can hear the difference between 16/44 and many Spotify 320kbps tracks.  Unacceptable for anything but background music.  If Spotify ever gets off its fat ass and releases its high res tier, I'll probably switch to that because I already have a Spotify family account for my wife and kids, and I think it's "radio" functionality is better than Tidal's.
