Description
Cayin’s pure Class A, single-ended triode design
The HA-300 MK3 continues Cayin’s pure Class A, single-ended triode design, while bringing meaningful upgrades in circuit design, transformer performance, power supply architecture, component selection, and overall craftsmanship. The result is a more refined, more stable, and more versatile flagship amplifier, with improved compatibility across a wider range of headphones, from sensitive IEMs to full-size high-end models.

Third-Generation Circuit Upgrade Preserving the Authenticity of Music
The HA-300 MK3 adopts a physically separated power supply and main amplifier chassis, providing cleaner energy delivery and improved isolation from interference.
Built around a new third-generation upgraded circuit, the amplifier retains the unique charm of Cayin’s classic single-ended tube topology while enhancing signal transmission efficiency and anti-interference performance.
The voltage amplification stage incorporates a low-noise regulated circuit with independent staged power delivery, preserving the integrity of the original audio signal and reproducing music with greater precision and realism.
In addition, the HA-300 MK3 has been specially optimised for IEM compatibility, making it suitable for a much wider range of headphones than before.
Two-Chassis Construction
The high-rigidity chassis structure helps suppress vibration and improve mechanical isolation, contributing to a higher signal-to-noise ratio and more stable sonic performance. The modular design also makes maintenance, upgrades, and product placement more flexible.
Secure Power Connection
The main unit and power supply are connected via an aviation-grade push-lock connector cable, designed for secure, stable transmission with low loss and protection against incorrect connection. Dust-protected terminals also improve ease of use.
Breakthroughs in Both Performance and User Experience
With greatly expanded compatibility, the HA-300 MK3 offers a wider sensitivity and power range, enabling it to drive everything from low-impedance IEMs to high-impedance full-size headphones. It is engineered to satisfy diverse listening needs with precision. At the same time, key acoustic specifications have been further improved, delivering cleaner signals, finer detail retrieval, and a more immersive listening experience.
Shape the Sound Your Way
All tubes used in the HA-300 MK3 can be replaced with compatible alternatives, giving users the freedom to tailor the sound signature to their own preferences and listening scenarios.
From subtle tonal refinement to dramatic changes in presentation, tube rolling opens the door to a wide range of sonic possibilities and a more personalised listening experience.
Versatile Connectivity for Every Listening Scenario
The HA-300 MK3 is equipped with a highly flexible interface layout designed to support a wide variety of premium headphones, speakers, and source components.
More Than a Headphone Amp
The HA-6A MK2 introduces a dedicated PRE-OUT output, elevating it from a headphone amplifier into the centrepiece of your audio system. Connect it to external power amplifiers or active speakers to create a refined desktop or small-scale Hi-Fi setup.
Refreshed family design – Refined in every detail
Premium Components – Meticulous Craftsmanship
DUELUND Coupling Capacitors
The HA-300 MK3 uses DUELUND coupling capacitors from Denmark, widely regarded as an ideal match for tube amplifiers. Their low distortion, low loss, and excellent signal transmission characteristics enhance detail, layering, tonal texture, and musicality.
Precision Volume Control
The amplifier combines a JRC MUSES 72320V high-fidelity electronic volume control chip with an ALPS 41-step attenuator, delivering low-noise, low-distortion volume adjustment with precise, smooth level control.
New Gold-Plated Tube Sockets
New premium gold-plated tube sockets provide better conductivity and more stable contact than conventional ceramic gold-plated pin sockets, reducing signal loss while improving durability and installation stability.
Classic Hand-Wired
Point-to-Point Construction
All electronic components in the HA-300 MK3 are assembled using Cayin’s classic point-to-point hand wiring technique, ensuring low-loss signal transmission and carefully balanced internal routing
Carefully Selected Matched Tubes
In HA-300 MK3, each tube used is hand-tested, matched, and performance-screened. Each amplifier also undergoes 48 hours of burn-in and listening evaluation before leaving the factory, ensuring excellent channel consistency and long-term reliability.
