Using Nucleus, Roon manages all your music – on hard drives, NAS, and streaming content – and allows you to play it on all the audio devices around your home. Nucleus is the best way to run Roon at any price. Just plug Nucleus into your network, connect your hard drives, download Roon remote apps (iOS, Android, macOS, Windows) and you’ll be ready to play music using a wide variety of audio devices, including AirPlay, Sonos, Roon Ready, Devialet, KEF, Meridian, Squeezebox, and a huge variety of USB DACs.
