ROON Labs

The Nucleus and Nucleus+ appliances were conceived to bring Roon to a wide audience of music lovers, particularly those who aren’t highly technical or interested in do-it-yourself (DIY) projects.

By tightly integrating high-performance hardware with an optimized operating system and purpose-built software, they provide a simple way to get the richest possible Roon experience.

The Roon Nucleus and Nucleus +

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.

The Roon Nucleus +

Fanless Roon appliance with Gigabit ethernet, 2x USB 3.0, internal
2.5" HDD/SSD bay, external power supply.
- Large libraries over 100,000 tracks
- Over six simultaneous zones
- Extensive DSP

They represent the culmination of an extensive product design and engineering effort, combining the Roon team’s years of experience designing media server hardware and extensive software development expertise.

The Nucleus product line was developed with several goals in mind:

  • A turn-key Roon Core that does not require a Mac, PC, or NAS

  • Computing power to support Roon’s requirements now and in the future

  • Ease of use - little to no customer support required after installation

  • Software and firmware updates downloaded “over the air” and managed by the end user

  • Reliable and robust operation - tamper-resistant and nothing to service

  • Audiophile-friendly - no fans or moving parts

Roon Subscription Required! We recommend the lifetime subscription.

Roon transforms the experience of browsing music. Artist photos, credits, bios, reviews, lyrics, tour dates, and composers are located automatically, then interconnected by links to build a surfable, searchable digital magazine about your collection.


And Roon finds all the same links between your personal files and the millions of tracks available on TIDAL, so you can start with the music you know, then explore and discover new music from the world beyond your collection.
In addition to music browsing, Roon is a multi-room, multi-user networked audio platform built to the exacting standards of audiophiles. It offers features like bit-perfect playback, DSD and PCM upsampling, multichannel playback, and signal path display.


Roon plays to a number of different types of devices on your home network Roon Ready, AirPlay, Sonos, Squeezebox, and Meridian – and can be controlled from Mac, Windows, iOS, and Android.
