Adagio 300B

A New Reference in Integrated Tube Amplification

Born from the DNA of the award-winning Auris Headonia 300B, Adagio is a reference-grade integrated amplifier designed to reveal the full emotional depth and tonal richness of the legendary 300B tube. Crafted for discerning audiophiles, it delivers 2×8W of pure Class A power through hand-selected components, custom double C-core output transformers, and automatic biasing set precisely at 75mA – extracting the finest performance from every 300B tube.

In the signal path, the combination of CV-181 (or 6SN7) driver tubes with zero global feedback architecture brings exceptional clarity, holographic imaging, and natural warmth. The OLED display shows all relevant information and includes a real-time VU meter, giving a perfect visual cue of what your ears enjoy.

Adagio offers 1 balanced XLR and 3 unbalanced RCA inputs, alongside Bluetooth connectivity for modern convenience. With speaker outputs for 4 and 8-ohm loads, it’s ready to drive a wide range of high-sensitivity speakers with control and finesse rarely heard in this class.

Built not only to impress, but to connect. Emotionally. Sonically. Perfectly.
