Air vs dedicated streamer

[spater]

Hi all.

Hoping for some wisdom!

I have a Devialet expert 250 pro.

I stream from my phone via AIR directly to the amplifier using the Tidal app.

I was considering getting a dedicated streamer (Wiim Ultra in particular), and connecting to the amp using a digital coax cable.

 Now I understand that I would still need to stream, but now to the Wiim instead of directly to the Devialet amp.

Has anyone done this exercise? Are there audible benefits to having this setup?

It seems like there would just be another link in the chain, so maybe a downgrade?

I’m a bit confused. How are you streaming to the amp from your phone via Air? I didn’t think that was possible. Do you mean AirPlay?
