Dismantling a no longer used Sonos multi-room setup. Part of that collection is a Sonos Port. If you are unfamiliar, the Sonos Port lets you add the Sonos experience to your existing stereo or receiver, and use it for multiroom listening.
Basically, you connect the Sonos Port to your traditional audio equipment to stream music, radio, audiobooks, and more from all your subscribed services. Control is done via the Sonos app and it also works fine with Apple AirPlay 2.
Using this you get to expand your existing stereo AND you can add Sonos wifi speakers to other rooms and use it to playback what you're listening to on your main stereo. Everything works together over WiFi. So you could say listen to your turntable not only in your living room but also your office, bedroom, bathroom, what-have-you.
I had two of these that I removed from my system. I have one left. It is priced quite fairly at $320, Approx 40% off retail and it is in like new condition.
Highlighted features:
* Line in for both digital and analog inputs
* Automatic 12V trigger to turn equipped stereos on when music starts to play
* Apple AirPlay 2 so you don't *have* to rely on the Sonos app if it isn't to your taste
