It has Wi-fi built in (which is how I use it) or it can do a wired LAN connection.
It does have Bluetooth, but I haven't checked that out yet. It can work with Alexa, Google Home, and Siri. There's a mic at the back, but you can pair it with Alexa and ask it to play from Amazon or other services, I think.
It has a built in dac, but has both a toslink and coaxial out.
There's even a digital line in and analog in.
So:
wired or w-ifi network > internal dac > analog out to stereo; or
wired or wi-fi network > digital out > analog out to stereo; or
Bluetooth > paired bluetooth speakers or headphones
They say it is Roon ready. It can do DLNA. I do not have any DLNA software or any NAS storage on the network, but I downloaded the Wiim desktop app. This app does not have the streaming services on it, but it can access and play the local audio files on my computer on the same network.
It's even got an EQ with various presets and a parametric EQ that I haven't messed with.
The reviewer who said it is like a Swiss Army Knife was right. Tons of features I probably won't use. I just got it since it was so cheap and I received a free Qobuz family subscription.
