Reference Dual Mono Power Amplifier Tune Three

Hybrid Power Amplifier with driver tubes and MOSFET Output Stage

Tune Three is a 2-channel power amplifier in Dual Mono configuration, which is designed to combine the best of vacuum tubes and solid-state transistors. A tube voltage amplifier and a MOSFET transimpedance amplifier in a unique circuit topology and with matched components, offer an outstanding listening experience with no limitations. The total absence of feedback allows the absolute purity of the amplified signal. It has been sounded with the best available vacuum tubes and audio grade elements.

Paired with the Tune Two preamplifier builds a true audio reference system of high aesthetics, functionality and driving capabilities.

Product details


User can select any of the 15 available colours for the front illumination, that match to his ambient aesthetics and dim them in 3 levels or even turn completely off.

Removable side panels for individual appearance, by changing color and/or material.

Wave dampening optimized chassis design for enhanced flexibility and stiffness at the same time.

FloatO integrated anti-resonance feet for quieter background and extended sound dimensionality.



Amorphous wooden fiberboard chassis dampens unwanted vibrations and mechanical noise feedback, resulting in lower noise floor and eliminating crosstalk.

High End luxury painting procedure MlCoat. Ultra-refined multiple coats of paint, offer a resistant and smooth surface.

Fusion of production methods, subtractive manufacturing (CNC) and additive manufacturing (3d-printing), along with a mix of materials (wood, metal, plastic, rubber), allows for stunning looks and launches unrivalled music playback.


VAcc battery emulator with custom wound mains transformers for power supply unaffected by network fluctuations.

Dual mono audio configuration with GStar single common earth point for total immunity from mains noise and ground loops.

Single Class-A tube amplification driver stage with 2x CV181 (or equivalent), light polarized and with no feedback.

High current MOSFET output stage.
