EISA Award — Best Streamer 2026–2027
"The beautifully crafted housing and streamlined design of the Primo Plus from Italy’s Volumio may look familiar, but the technology inside this streaming DAC is entirely new."
Advanced Streaming DAC
Primo Plus builds on the original Primo with a completely redesigned audio architecture. Two ESS ES9039Q2M DACs operate in a dual-mono configuration, supported by upgraded op-amps, dedicated analog and digital regulation, refined filtering, and an ultra-low phase-noise master clock.
Flexible Digital Connectivity
Connect network sources, USB audio, local storage, optical and coaxial digital sources, or Bluetooth. Primo Plus can feed an amplifier through balanced XLR or unbalanced RCA outputs, and its hardware volume control allows direct connection to a power amplifier when used as a preamplifier.
Multiple Connectivity Options to Explore
Giving you everything you need to build a truly flexible system, with USB-C and USB-A ports, optical and coaxial inputs, and premium balanced XLR and RCA outputs that deliver a clean, confident signal to any amplifier.
Volumio Premium Built In
Primo Plus runs Volumio and includes Volumio Premium features, bringing together supported streaming services, local and network-attached music libraries, internet radio, Bluetooth sources, connected storage and more in one unified interface.

Both models deliver Volumio Premium, high-resolution streaming, balanced XLR and RCA outputs, Gigabit Ethernet, dual-band Wi-Fi and Bluetooth 5.0. The difference is how far you want to take the DAC, connectivity and system-control side of the experience.
