The Evolution Stream Server is the perfect choice for music enthusiasts, offering seamless access to your digital music library whenever you desire.
- Effortless Control & Seamless Performance - Install and run multiple applications effortlessly for an uninterrupted experience. Manage your music server with ease using the VitOS Manager mobile app.
- Precision Audio: Equipped with dual dedicated TCXOs (Temperature Compensated Crystal Oscillators), one for each Ethernet port, this system prevents clock signal interference, ensuring highly accurate timing. The 10MHz TCXO minimizes network latency and jitter, providing flawless audio playback.

- Interference-Free Listening: EMI noise-filtering technology effectively eliminates electrical interference, ensuring a pure listening experience.
- Optimized Storage: Equipped with a high-performance 250GB SSD optimized for VitOS and application storage, the all-flash drive delivers low latency and ample capacity. Performance is further enhanced by an EMI absorber and a dedicated power regulation circuit, isolating power noise for superior audio playback quality. We advise against expanding the internal storage, as using an off-the-shelf SSD may degrade performance. For users with large local music libraries, external storage is recommended.

Latest version:
Vitos for EVO Stream:1.2.9966
VitOS Manager For iOS :1.5.8 (Build 10013)
VitOS Manager for Android : 1.5.8 (Build 10014)
- This version added AirPlay and shared access to files on a network. Omnia devices will be able to access VitOS devices to stream music from local libraries.
To get started, connect VitOS Manager to Evolution Stream, then install the Orbiter Plugin and DLNA Renderer as the essential components.

Spotify Connect currently exists within VitOS Manager. Streaming services supported under VitOS Orbiter are Tidal Connect and QQ Music. Qobuz is currently accessible through Roon and may become available directly in VitOS when Qobuz Connect launches in 2025. For the latest updates and potential additions of other streaming services, please visit https://us-store.nuprimeaudio.com/vitos-quick-start-guide/
Tidal Connect & QQ Music
Ensure the Tidal Connect or QQ Music plugin is active when using the respective streaming service.


USB Audio DAC Setting
If a USB DAC is connected to the Evolution Stream, navigate to More Settings -> Device Settings to check the configuration.


Local NAS
If you have a local NAS device, enter its IP address, and if security is required, provide the login ID and password.


NuPrime Omnia devices function as streaming endpoints, acting as receivers for music data. In contrast, NuPrime devices running on VitOS include a computing platform, allowing the operating system and applications to be updated over time.
Usage Guide:
- Use native streaming service apps (Qobuz, Tidal, Spotify etc) to connect to VitOS or Omnia devices.
- Use Omnia App to setup and group Nuprime Omnia devices for multi-zone streaming.
- Use VitOS based server devices to manage local music libraries.
- Use Omnia App to locate local music libraries for streaming.
