Inside the mysterious finned black box
When designing Nucleus, we ultimately decided to produce two models. They’re identical in all respects except for raw computing horsepower. We wanted to provide options based on specific needs and adjust device costs around the use scenario.

Exceptional system, ease of use
I couldn't be more pleased, exceptional system, sound and ease of use! Well done Roon!
Craig Metz
Customer service is outstanding
This Nucleus is a great, easily connected piece of hardware. The sound of music, when the Nucleus is connected via USB to my McIntosh Receiver, is delightful! Perfect!
You Won't Regret It!
With the Nucleus, I never have to think about updates because they're downloaded automatically without any input from me.
No glitches of any sort. Does exactly what it's supposed to. Much better than using my IMAC as a Roon Core
Keith Alan Jackson
This thing totally works
I made it the center of my home audio system. It completely rocks. It's completely silent and fast as hell. Set it up and forget it. This is so worth it.
Theodore V. MccOnnell
A no-regret purchase
It literally took me a minute to set up and get running. The Nucleus will even update itself automatically when needed. Once you set it up, you never need to worry about it again.
