simply the best way to
Experience Roon

Made by roon

The brain behind the Roon experience is the Roon Core. Every aspect of Nucleus – hardware, operating system, and software – was developed to provide a silent, high-performance, power-efficient Roon Core, by the same team that created Roon.

Simply the best

Nucleus is the easiest, fastest way to get your Roon system running. No computer or networking skills required. Just take it home, plug it in, and download Roon apps for your mobile devices and computers. Nucleus keeps itself current with automatic updates. 

« Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. »

Antoine de Saint-Exupéry

built for sound quality

Nucleus has no fans or moving parts of any kind, and its minimal operating system is tuned to deliver high-performance audio. Whether it’s in your listening room, on your desk, or in a rack, you can be confident you’ll be getting the best sound from any music server. 

developed with intel

The rich Roon experience requires modern computing power, and the more the better. We worked with Intel to develop Nucleus to support Roon now and in the future. It has horsepower to spare for large music libraries, multi-room streaming, and DSP.
