Qobuz vs Airplay

@dokosan i’ve had the SIM Audio 390 in my system in the past and I think it is a really good product, very well built and accomplishes a lot of things. I thought the Mind software was very good and SimAudio does a good job of maintenance. I think the advice you got from SimAudio is probably about right from my experience. 

I have both Qobuz and Tidal. I have less experience with Apple Music and Amazon, but I understand that both have improved significantly in the last few years and there are people who prefer one or the other over what I use. While I generally prefer Qobuz, I know plenty of people who like Tidal better and it can vary from track to track. There is no objective “truth” here, it’s a subjective preference and we all hear differently. Easy enough to try both and choose what you like, and I suspect your preference concerning the user interface will matter a lot more than sound quality.
Again, that’s just my opinion, but I would say to someone who says that one is “objectively“ and definitively better than the other, let me see your objective proof. I still prefer the sound of a well recorded vinyl album on a high-quality turntable to streaming, but that’s just me, doesn’t make it right for you. And really, the ability to access millions of tunes at CD quality or better(And that’s another big debate concerning high rez) for 15 or 20 bucks, a month is incredible value that greatly enhances the whole experience.

I’d pick the service you find the easiest to use and be happy.

I’ve tried all the major streaming services.  Qobuz is the best combination of music quality, selection, ease of use and price in my experience.  I no longer use Airplay except when connected in my car.  

If the Mind can do Qobuz Connect or Tidal Connect give these a try not a bad UI. 
 

As to Apple Music Airplay vs Qobuz yes there’s a difference but it may not be important enough for you. Try and see. 

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.
