Sound with otherworldly resolution and depth!
MK4 equipped with newly developed ICs
Equipped with SATRI/HIBIKI ICs. Current output delivers overwhelming realism and ultra-high resolution.
This is a new model featuring the MK4 circuit, which further evolves from the HDA-5210mk3. It was developed with the goal of playing headphones at the highest sound quality.
Sound quality refinement with MK4 circuit
By adding the new HIBIKI-IC to the SATRI-IC, the MK4 offers thicker sound, more information, and greater realism compared to the MK3.
- Fast startup: The amplifier quickly reaches full performance as soon as it is powered on.
- Non-degrading attenuator: The gain is controlled by a 23-step attenuator (continuously variable up to 20dB). Unlike normal volume controls, there is no deterioration in S/N ratio even when reducing the volume.
Advantages of current output (high impedance current output)
The HDA-5210mk4 features high-impedance current output.
- Reduced distortion: Driving headphones with current results in less distortion compared to voltage drive, allowing for more precise reproduction.
- Information retention: Using headphones with minimal impedance frequency fluctuation via current output allows you to hear a wealth of information not possible with voltage drive.
- Wide compatibility: Current output can drive very high-impedance headphones, making it compatible with almost all headphones.
- Simultaneous output: Current and voltage outputs can be used simultaneously. However, the sound will change as the current output reflects the characteristics of headphones connected to the voltage output.
Unique sound quality evaluation (manufacturer & review information)
- Startup speed: Extremely fast startup enables dynamic and powerful bass.
- Realism and space: Deep, vast, and quiet background with spatial presence, delivering overwhelming realism and resolution.
- Fatigue-Free Listening: With remarkably natural playback and rich, immersive live sound, you can listen for long hours without feeling fatigued.
- Satisfaction: Comfort exceeds expectations, and once you listen, you'll find it hard to let go. Its sound stands apart from the many headphone amplifiers available.

Overwhelming Silence and Rapid Response
The first thing that stands out with the HDA-5210mk4 is the depth of silence and the sharpness the moment a sound emerges. In the mk4 generation, the circuit and power supply have been revised, significantly lowering the noise floor. Sounds rise from a deep silence with a clear three-dimensional quality, and the speed unique to the SATRI circuit can be distinctly felt.
High Resolution Yet Natural Musicality
Resolution is extremely high, with no detail becoming vague, yet it avoids the so-called cold monitor sound. Sound contours are sharp, with excellent spatial clarity. At the same time, the flow and dynamics of the performance are natural, conveying the music as a coherent expression without fragmentation.
Balance of Driving Power and Control
Even when headphones with different impedances and sensitivities are connected, the tonal character does not collapse, maintaining stable control at all times. The bass is tight and solid without exaggeration, with clear rhythmic definition. The high range is expansive without being harsh, making listening for long periods comfortable.
Neutral Character Without Coloring
The HDA-5210mk4 is not a type of amplifier that makes the sound flashy. It brings out the unique character of headphones and DACs as they are, honestly reflecting the overall quality of the system. Therefore, depending on the combination, the expression of the sound can change significantly, offering the enjoyment of fine-tuning the setup.
A device that brings headphone playback closer to 'reproduction'
It is not overly analytical, yet it leaves no ambiguity. Thanks to this exquisite balance, it gives you the sense of not just 'listening' to music but 'perceiving' it. The HDA-5210mk4 can be considered an extremely high-quality amplifier for users who want to take the resolution and realism of headphone playback to the next level.
