There are a lot of different options to consider, ranging in complexity, cost and which streaming service you're going to use. You might want to look at a single unit combined streamer/DAC as a starting point. Many of these provide for different streaming service options such as Spotify, Tidal, Qobuz, etc. FWIW, I use Qobuz as I found it has the best sound quality.

You'll also need to think about how your going to connect the streamer/DAC to your router. Many prefer to use the built in WiFi on a streamer/DAC, however this can be glitchy depending on your home wifi set up. In my system I found that using an Ethernet cable to my router through an AC extender proved the most reliable.

There are a lot of options for single box streamer/DAC's out there. I'm pretty sure that some will recommend a separate streamer and DAC set up. The inexpensive WiiM and Bluesound offerings are pretty basic and straightforward to set up, but don't offer really good sound quality for high resolution music IMHO.

I suggest you check out offerings from Eversolo and Cambridge Audio as well.

Do you plan on playing your own digitized music say from a USB drive.

If so this increases some of your options
