How To Stream Internet Radio

Humbly soliciting ideas on how best stream FM radio. My NAD C446 digital media tuner appears to be giving up the ghost, and no one appears interested in attempting to fix it.

I need to stream only FM radio, not music streaming services. I would prefer a separate box, with a display, to connect to my amplifier, one that has the conventional-style interface of a tuner, and not use a computer to do the streaming. I would want an optical connection to the amplifier.

Is there still such a thing? I'm woefully out of touch with all the recent moves in streaming and may be chasing something that does not exist.

The rest of my system is (no sneering, please) a NAD C390DD amplifier, ProAc Response D20R speakers; the music source is a Mac Mini playing through Audirvana.
Any thoughts are much appreciated. Thank you.
The Bluesound Node 2i solidly out classes the fidelity of the Sangean or Ocean products by light years. It streams directly off the router by wire or WiFi. Through the Bluesound app it has free internet radio. Turn off your Mac device after selecting your radio station if you want. It will keep playing. You’ll need to go back to the app to change stations though. Bonus. It can stream just about anything if you change your mind about that. It has rca outs. Just plug them in to the preamps tuner input.  Has optical out as well.
I had that. Not user friendly. Fidelity sucks big time. Drop outs galore on WiFi.
Yup, a Bluesound Node is what fits the bill.
Any iteration will work as good as the latest.
