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.

 Free 1 year subscription

As of October 1st 2020, Roon offer 1 year of free Roon software subscription included in the box with every purchased Nucleus or Nucleus+. This will arrive either by card within the box itself, or by email. Read our FAQ for more info.

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.

Why Nucleus?

Roon Labs has always had an open approach to providing its software for the best user experience. That's why you can continue to install Roon on your normal laptop or desktop PC, or you can even make your own bespoke server solution using their freely available installation files. However, Roon Labs also wanted to manufacture a server - not only so customers could get local dealer support, a warranty and all the conveniences that go with it - so customers could purchase a plug-and-play solution that's purpose designed to unlock and exploit every feature within Roon.

Free 1 year Roon software subscription

  • Though each license is matched against a Nucleus or Nucleus+ purchase, it is not limited to use with that device. You can use it on anything that can run Roon.
  • If you are a new user at the time of purchasing Nucleus, your free year can be used immediately. If you are already part-way through a year the free period will be added to the end of your current term eg. 6 months left would turn into 18 months before your next charge for the software.
  • If you are already a Roon lifetime subscriber, the Roon license included can be used on any other Roon server or device.

What is the difference between this Nucleus and the original version?

The Nucleus and Nucleus+ models released in 2018 (now called Rev A) have the same technical ability as the later 2019 model (Rev B). In the revision, Roon Labs moved production from the Far East back into the US, changed to more eco-friendly packaging, improved production processes and changed the chassis. The principle benefit of the chassis change is it allows for access to a second HDMI port on the back panel, and increases the internal space for a hard drive from 9mm to 15mm (as of August 2019 that covers storage drives up to 5TB).

Is there a full user guide available?
