Auris Luminis Integrated Amplifier

A 20 W pure Class-A parallel single-ended 300B amp with autobias

Building upon the award-winning design principles of Adagio, Luminis elevates single-ended performance to a new level with a parallel 300B topology, delivering a commanding 2×20 W of pure Class-A power. This reference-grade integrated amplifier is designed for those who demand the full emotional and dynamic potential of the legendary 300B tube. Luminis supports both standard and MESH 300B variants.

With zero global feedback, fully automatic biasing at 75 mA per tube, and a dual 300B output stage per channel, Luminis offers unmatched tonal richness, holographic depth, and low-level detail—even with more demanding speakers. The CV-181 / 6SN7 input stage preserves signal integrity with elegance and musicality.

An intuitive OLED display with integrated VU meters provides real-time visual feedback. Connectivity includes one balanced XLR input, three unbalanced RCA inputs, Bluetooth wireless streaming, and speaker terminals for both 4 Ω and 8 Ω systems.
