Mac vs streamer.

@m669326 Search for audio optimization tools for the operating system and device you are using.

Deezer offers tips to optimize Deezer. They are limited, but may be helpful if you have not applied them.

If you’re technically inclined, I’d go with a Raspberry Pi loaded with whatever OS that’s specialized for music playback (e.g. Volumio, moOde, piCorePlayer, etc.). You’ll save money and it’s a fun project.

Currently using my Pi w/ Volumio and I can’t tell a difference between that and my Oppo UDP-203 w/ VanityHD board (which reclocks the SPDIF output for lower jitter) all going into a Benchmark DAC3.

I can also stream from the YouTube Music app to the Pi using UPnP on my phone and Volumio has support for Spotify too, I think.

I tried looking for ways to optimize Deezer SQ with a Mac. I found nothing.

Here is very general (and basic) info from Deezer support.

If you are open to digging deep, search 'optimizing Mac OS for DAW' (Digital Audio Workstation).  Be specific with your OS version.

Here is one search result:

***Much, much easier to run Audirvana, JRiver, etc.***

Here is a partial list of other options:
