Description
The DENAFRIPS ARTEMIS HPA has been engineered for headphone enthusiasts who demand the same level of performance from personal listening as they expect from a world-class two-channel audio system. Designed entirely from the ground up, the ARTEMIS combines DENAFRIPS' flagship analogue technologies with a fully discrete, true balanced Pure Class A amplifier architecture to deliver an uncompromising headphone listening experience.
Rather than simply increasing output power, the ARTEMIS focuses on preserving the integrity of every musical performance. Its fully balanced signal path, precision analogue circuitry and ultra-low-noise linear power supply work together to reveal extraordinary levels of detail, natural tonal balance and effortless dynamics across an extensive range of headphones.
Whether listening through high-impedance dynamic headphones or demanding planar magnetic designs, the ARTEMIS provides exceptional control, allowing vocals to sound more lifelike, instruments to occupy clearly defined acoustic spaces and subtle musical textures to emerge naturally from an exceptionally quiet background. The result is a listening experience that feels open, spacious and remarkably engaging without becoming analytical or fatiguing.
At the heart of the ARTEMIS is a premium four-gang, metal-alloy shielded 24-step attenuator that provides highly accurate volume adjustment with excellent channel matching throughout the listening range. Combined with DENAFRIPS' fast-recovery ultra-low-noise linear power supply, premium hand-matched discrete components and oversized heatsinks operating in Pure Class A bias, every aspect of the amplifier has been engineered to maximise transparency and long-term musical enjoyment.
Designed to integrate seamlessly into premium desktop and dedicated headphone systems, the ARTEMIS offers multiple balanced analogue inputs together with balanced and single-ended headphone outputs, making it an ideal partner for flagship DACs including the DENAFRIPS PONTUS, VENUS and TERMINATOR Series. Its shared chassis dimensions also allow it to aesthetically complement the DENAFRIPS component range.
Highlights
Flagship Pure Class A Headphone Performance
The ARTEMIS HPA has been engineered to deliver reference-level personal audio performance through a fully balanced Pure Class A amplifier design. Every aspect of its circuitry has been optimised to reproduce music with exceptional transparency, natural tonal balance and effortless musical realism.
True Balanced Discrete Architecture
A fully balanced, fully discrete analogue signal path preserves the integrity of every recording while minimising unwanted noise and distortion. The result is outstanding channel separation, expansive soundstaging and remarkable clarity across an extensive range of premium headphones.
Precision 24-Step Volume Attenuation
A premium four-gang, metal-alloy shielded 24-step attenuator provides highly accurate volume adjustment with exceptional channel matching. This precision design maintains signal purity while delivering smooth, repeatable control throughout the listening range.
Ultra-Low-Noise Linear Power Supply
The ARTEMIS employs a fast-recovery low-noise linear power supply engineered to provide exceptionally clean and stable power to every stage of the amplifier. This contributes to a remarkably quiet background, improved low-level detail retrieval and effortless dynamic performance.
Designed for Serious Headphone Systems
Whether driving high-impedance dynamic headphones or demanding planar magnetic designs, the ARTEMIS provides the current capability, control and refinement expected from a reference-quality headphone amplifier while integrating seamlessly with premium DACs and analogue source components.
Design & Engineering
Fully Balanced Pure Class A Circuit
The ARTEMIS employs a fully balanced, fully discrete Pure Class A analogue topology that preserves signal integrity from input to output. Operating entirely in Class A allows the amplifier to deliver exceptional linearity, low distortion and a naturally effortless musical presentation.
Precision Stepped Attenuator
Instead of a conventional volume potentiometer, the ARTEMIS uses a premium four-gang, metal-alloy shielded 24-step attenuator. This precision approach provides excellent channel balance, repeatable volume adjustments and long-term reliability while preserving the integrity of the analogue signal.
High-Performance Linear Power Supply
A fast-recovery ultra-low-noise linear power supply provides exceptionally stable power to every stage of the analogue circuitry. Combined with carefully selected discrete components, it creates the quiet electrical environment necessary for outstanding transparency and dynamic expression.
Premium Discrete Component Design
Every stage of the ARTEMIS has been constructed using carefully selected discrete components and meticulous circuit layout. This design philosophy allows DENAFRIPS to optimise every aspect of analogue performance while maintaining exceptional reliability and consistency.
Precision CNC Aluminium Chassis
The precision-machined aluminium enclosure provides excellent mechanical rigidity while shielding sensitive analogue circuitry from external interference. Large external heatsinks support continuous Pure Class A operation while complementing the premium industrial design shared across the DENAFRIPS product range.
RockOnAV's Take
The ARTEMIS HPA demonstrates that personal audio deserves the same level of engineering found in a world-class loudspeaker system. Rather than simply providing higher output power, it focuses on preserving the natural character of every recording while delivering the control, refinement and transparency required by today's premium headphones.
What impressed us most is its effortless presentation. Music flows naturally with exceptional detail, outstanding image stability and convincing three-dimensional space, allowing headphones to disappear and the performance itself to take centre stage. Even demanding planar magnetic headphones remain composed, dynamic and highly engaging.
For enthusiasts building a dedicated desktop or reference headphone system, the ARTEMIS HPA provides an exceptional amplification platform capable of partnering with flagship DACs and premium headphones while delivering long-term performance worthy of a serious audiophile investment.
Who It's For
The DENAFRIPS ARTEMIS HPA is designed for discerning headphone enthusiasts seeking reference-quality personal audio. It is ideally suited to listeners using premium dynamic or planar magnetic headphones who want greater transparency, exceptional control and the musical refinement of a dedicated Pure Class A headphone amplifier.
