Volumio Primo Plus

Primo Plus is engineered from scratch to take our acclaimed Primo to a whole new level, combining 2 x ESS ES9039Q2M in a dual mono layout with upgraded OPAMPs, an ultra-low noise dual linear power supply, refined filtering, and a high precision clock that cuts jitter and lifts overall resolution.

It also introduces a broader range of digital inputs for greater system flexibility. USB-C handles native high-resolution audio, USB-A supports external storage, while optical, coaxial, Bluetooth, and full network streaming cover every modern source with ease. With the latest Volumio OS optimizing the entire signal path, the result is a deeper soundstage, sharper imaging, and a more natural sense of presence. Primo Plus doesn’t just improve on the original. It elevates every aspect of performance.

Primo Plus is designed to extract the purest possible signal from your music, starting with a high-precision clock that keeps phase noise and jitter extremely low for a cleaner, more stable presentation. Its advanced power architecture uses LC filtering and dedicated regulation for analog and digital sections, preserving subtle detail and control.

 You can shape the sound with 8 selectable DAC filters or switch to NOS mode for a more natural, unprocessed character. The fully balanced output stage maintains impressive channel separation, and the built-in volume control makes it easy to run Primo Plus directly into a power amplifier for a streamlined, high-performance setup.

Primo Plus is made for people who simply love music and want a more expressive, more engaging way to hear it. Fans of the original Primo will appreciate how much more power and refinement it brings, while anyone building or upgrading a system will enjoy how easy it is to set up and use. The included remote makes everyday control from the moment you turn on the device.

Primo Plus can be matched perfectly to any amplifier thanks to 8 selectable output levels from 0.5 to 6.30 Vrms, letting your system perform at its very best. And if you prefer a clean, compact setup, its built in preamp lets you connect straight to a power amp or active speakers for great sound with minimal effort.

On board, the Primo Plus runs Volumio, the platform that brings all your digital music together in one smooth and unified experience. Streaming services, local files, CDs via an external drive, Bluetooth sources, and connected storage are all managed from a single, easy interface, making your entire music world feel effortless and organized.

Volumio connects smoothly with major streaming services, letting you access Tidal, Qobuz, Spotify, and HighResAudio from the same interface. You can move between them freely, browse libraries, and play your saved music without changing apps or disrupting playback.
