Enjoy the warm, clear sound of valve amplification from all your audio devices with our new v50 amplifier.

The v50 valve amplifier combines the latest in connectivity. Superior valves to provide the warm sound associated with tube amplifiers and a high-quality built-in DAC.

The inclusion of a Bluetooth (aptX) receiver allows all your Bluetooth enabled devices to connect effortlessly with the v50.

Available in Black


Following on from Blue Aura's multi-award winning v40 amplifier, the new v50 has been upgraded to offer a more powerful and versatile amplifier.

The v50 power is supplied courtesy of bigger toroidal transformers, headphone facilities have been added, and the loudspeaker connection terminals have been upgraded. A backlit Vu meter is supplied to monitor levels and the European ECC83 tubes deliver a harmonically rich sound, detailed lower frequencies and warmer high end.

Connect tablets and smartphones by Bluetooth, CD Players and Turntables by RCA Auxiliary, and PCs and laptops using USB.

The v50 also benefits from the aptX Bluetooth codec. aptX has revolutionised the Bluetooth listening experience by reducing the bit rate without affecting the audio quality, resulting in CD-quality sound.

A subwoofer can be connected to enrich the overall music experience.



The v50 Blackline has been designed to provide the best possible sonic performance.
The transformers are high-efficiency toroidal type, offering better heat dissipation and low leakage current resulting in very low distortion levels.

The use of European valves help to produce the warm, rich sound associated with valve amplifiers.

A brushed aluminium, ergonomically designed remote control is provided.

A Vu meter monitors sound intensity levels and the backlit display is fully adjustable by a control knob on the rear of the amplifier.

High quality, gold plated binding posts with thumb nuts are fitted to ensure the connecting cables are held securely, whilst ensuring the signal path from the loudspeakers to the amplifier meets the least possible resistance.
