Nucleus is the center of your Roon music system. It’s the housekeeper, the traffic cop, and the brain that takes care of the music in your life. 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.

Aside from being a powerful, fanless music server, what sets Nucleus apart is that it’s powered by Roon OS – a fast and lightweight operating system optimized to do just one thing: browse and play music. Roon is a multi-room, multi-user networked audio platform built to the exacting standards of audiophiles, so it offers features like bit-perfect playback, DSD and PCM upsampling, multichannel playback, and signal path display.

As well as distributing music throughout your home, Nucleus also offers the very finest performance possible when connected to a USB DAC. A computer source has never sounded this good before.

Nucleus or Nucleus+?

Both the Nucleus and Nucleus+ servers look and function in exactly the same way. Their difference is primarily down to the Intel® processor used in each model, which shifts their speed and workload capacity.

The standard Nucleus is suited to smaller multi-room environments, or for installations where complex DSP processing is not required. It's also suited to smaller library sizes.

Nucleus+ is the more advanced solution, for complex or high-end environments and for lightning-fast handling of larger music libraries.

See our Technical Data for more information.
