Check out the Dayton Audio WBA28. Very inexpensive, but works. I have an older model which allows me to connect my iPad/iPhone Tidal app wirelessly to this unit, and it then connects to my older PS Audio DAC that has no wireless connection. I use the optical connection available.
It also has an app which allows you to connect to a wireless server if you have one, which I also do, but more rare. You can also use their app to connect to Tidal, but I never do, and connect directly with my Tidal app on my iPad. Just select the WBA as your source on the iPad and you are ready to go.
In this way you can keep what you have. If you decide on a dedicated streamer down the road, not much of a loss.
