Powerful and transparent.

No other headphone amp offers so much power, yet has so few components on the signal path to temper with your music.

Conventional head amp designs use IC Opamps on their signal paths. And each IC opamp contains over 50 inferior components which block and distorts music.

Outputting over 4 watts per channel into 16ohm, the Soloist is tailored with a symmetrical current feedback circuit with only 21 components on its signal path. Its signal path is so short and with so little blockage on it, that it can achieve amazing sound.

Sustained, peak Performance, constantly.

Over-killed transformer plus over killed power supply equate to peak driving power in any situation with ease.

The Soloist outputs 4 watts per channel (8 watts for stereo) into 16ohm. To achieve this specification most conventional designs will settle for a 24 watts transformer. We on the other hand know the difference between achieving it momentarily and sustaining it there all the time. Hence we have implemented a 35VA tailored design transformer which ensures that the Soloist outputs at 4 watts constantly, without breaking a sweat.

The Soloist power supply is built around a noise-filtering network that employs twice as many filtering stages compared to the conventional designs resulting in superior noise rejection. Fed by its 35VA transformer, it delivers clean and stable power. The result is pure music against a pitch-black background.

Beautiful, purposeful aluminium enclosure.

The most beautiful enclosure ever made for a headphone amplifier is also the most efficient heat-sink ever made for a headphone amplifier.

Operating in pure Class-A, the Soloist generates a lot of heat. Music sounds great but the heat was the necessary evil which could harm its many components.
The enclosure was constructed with CNC machined aluminium to act as a giant heat-sink, which allows the Class-A headamp to run cooler, and remain optimised.

Perfect synergy with the rest of your system.

Variable Output Stage (VOS) enables our design to match well with any type of headphone systems and speaker systems. It ensures synergy when your system evolves through time.

A more stable and 3 dimensional sound stage.

Our 24 steps attenuator is built with 99% matched resistors. It is the most accurate volume control in the industry and we know it is the only way to create a stable and 3 dimensional sound stage.

Less noise, more music.

We tailored power filtering networks with discrete components and each filtering stage optimised for its application. The result is an energetic and engaging music reproduction.
