New to streaming question

I'm using the built-in DAC of the Naim Uniti and my settings in Qobuz are all enabled to play 24/192.  I use the Qobuz app to play tracks that get sent to the Naim via Chromecast so might this be the issue?  If there's a better connectivity scenario for playing Qobuz to the Naim I'd love to find that out.

I’m pretty sure Chromecast does not have 24/92 capability.

Does your Naim support Qobuz directly?  Please see below  

”Qobuz support will be rolled out to owners of Naim streaming devices via a free over-the-air firmware upgrade, the update will give Naim owners seamless access to Qobuz services. The music on offer from Qobuz includes true high-resolution streaming at qualities of up to 24-bit/192kHz, and all from within the Naim control app”. 

Hi Mike,

I don't think you need Chromecast in the chain. Your Naim Uniti Atom should stream directly from your ethernet connection, not through Chromecast. Here's what it says on the Naim Uniti Atom Headphone Edition page from Naim's website:

 Easy App control – in one room or many
The Naim App – available for Apple and Android devices – makes it simple to control your Uniti Atom Headphone Edition, and even link up other music systems around your home into a stunning multi-room set-up.

Use the App to access all your music, including your favorite radio stations, streaming services and playlists, and explore artist discographies and biographies.

Uniti Atom Headphone Edition works seamlessly with other Naim streaming products, including Mu-so systems. Choose the same song in beat-perfect sync or play different music in different rooms. You can also pair Uniti Atom Headphone Edition with other AirPlay 2-compatible wireless speakers via the Apple Home app, or with other Chromecast built-in devices via the Google Home app.

I was thinking it was Chromecast.  I've been using the Quboz app on my phone and streaming via Chromecast because Quboz native through the Naim app won't let you search any artists, it only lets you search through your favorites which is really clunky.
