The Reference Parallel 300B Integrated Amplifier
The Power of 300B, Multiplied
Luminis takes the unmistakable musical character of the legendary 300B triode and gives it greater scale, authority and control.
Built around a parallel single-ended topology with two 300B output tubes per channel, Luminis delivers 2 × 20 W of pure Class A power while preserving the natural tone, dimensional soundstage and emotional immediacy for which the 300B is renowned.
Designed for listeners who want authentic single-ended triode sound without being limited to the most sensitive loudspeakers, Luminis combines traditional tube architecture with automatic biasing, flexible connectivity and intuitive everyday operation.
Luminis brings greater power and control to the classic 300B listening experience.
300B Mesh Ready
Two 300B output tubes operate in parallel in each channel, delivering greater dynamic range, stronger bass authority and 2 × 20 W of pure Class A power.
300B Mesh Ready
Compatible with standard 300B tubes and selected 300B Mesh plate variants, allowing the amplifier’s character to be refined according to the listener’s system and preferences.
Automatic Bias Control
Each 300B tube is automatically biased at 70 mA, maintaining stable operating conditions and consistent performance without the need for manual adjustment.
CV181 / 6SN7 Input Stage
A carefully implemented CV181 / 6SN7 driver stage provides natural harmonic structure, openness and the effortless flow expected from a reference tube amplifier.

Unmistakably 300B
The parallel 300B output stage gives Luminis the ability to drive a wider range of loudspeakers while preserving the qualities that make single-ended triode amplifiers unique.
The additional power is not used to make the amplifier sound aggressive. It allows music to breathe more freely, with greater dynamic headroom, stronger low-frequency control and an effortless sense of scale.
Double C-Core Transformers
At the heart of Luminis are custom-designed, hand-wound double C-core output transformers.
Developed specifically for the parallel 300B output stage, they provide wide bandwidth, low coloration and excellent energy transfer while preserving low-level detail and tonal integrity.
Dedicated 4 Ω and 8 Ω speaker outputs allow optimal matching with a broad range of loudspeakers.
