Any of these options will serve your setup well:
Option 1 - if you do not need bluetooth, remote control or XLR outputs:
SMSL SU-1 DAC (85€ in France).
Option 2 - if you need bluetooth, remote control and XLR outputs:
SMSL D-6S DAC (199€ in France).
If you choose the SMSL SU-1 DAC, you can spend the extra money and have a lot more fun building an inexpensive but very good Raspberry Pi-based audio player. We have several of these players in our workplace and they run reliably 24/7 (with tweaked /boot/ config file to keep the Pi's electronics cooler).
The DAC connects to the Raspberry Pi via a USB cable (power and audio). You can easily control the player from your computer, phone or tablet. The player gives you access not only to your audio files (on your computer, external USB drive, etc.) but also to a wide range of free internet radio stations (a growing number of which offer high quality lossless audio).
For the Raspberry Pi based player:
1x
Raspberry Pi 5 4GB, ~ 70€ (other Raspberry's like the Pi 5 2GB, Pi 4 4GB or Pi 4 2GB will also do the job).
1x
Raspberry Pi aluminium box, ~ 15€.
1x Power supply, type USB C, 5V, 3A (a good, newer smart phone power supply will do).
1x SD card (this will hold the player's Volumio operating system, 16GB is more than enough, but you can use a larger one).
1x
Volumio Music Player, free / open source software:
