Cayin HA-6A MK2 is based on its predecessor and features a two-chassis design, upgraded vacuum tubes, and a special preamplifier output.
Class A Headphone Amplifier
HA-6A MK2 is a class A headphone amplifier equipped with KT88 output tubes. The driver tubes amplify the signal voltage with high linearity, while the KT88 tubes provide full, undivided power to ensure maximum musical integrity. Cayin has developed an amplification scheme that independently adjusts the operating current of each tube stage and connects it to a clean and stable power source, allowing the HA-6A MK2 to fully convey the rich tonality and musical depth characteristic of class A design. With a power output of 3000mW (TR) or 4500mW (UL) per channel, the HA-6A MK2 offers high precision and musical performance for a wide range of headphones.
Uncompromising Sound
Designed to deliver uncompromising sound quality, HA-6A MK2 features a two-chassis design that isolates the power source to reduce noise levels and enhance detail. Each amplification stage is independently regulated to minimize interference, and a special copper cable with silver plating ensures efficient current delivery without loss.
Enhanced Headphone Amplification Scheme
High-quality components have been added to the headphone amplification scheme, resulting in breakthrough performance and usability. Its wide compatibility and increased power output allow for connecting a greater variety of headphones.
High-Voltage Rectifier
Equipped with two JJ GZ34/5AR4 rectifier tubes, providing high and stable output power.
Voltage Amplification Stage
Driven by two JJ 12AU7/ECC82 dual-triodes, the amplifier provides increased signal amplification while preserving fine details and layering.
Class A Power Amplifier
Using a matched pair of Genalex KT88 tubes, you can reproduce the natural tonality of music with rich, immersive sound.
Matched Impedance Headphone Output
Built-in output transformers provide outputs with matched impedance for low (8-64 ohms), medium (65-250 ohms), and high (251-600 ohms) loads, ensuring natural, balanced sound. With 6.35mm, 4.4mm, and 4-pin XLR outputs, it delivers up to 4500mW per channel for demanding headphones, while the optimized 4.4mm connector is suitable for sensitive IEMs with reduced output power and improved signal-to-noise characteristics.
Dual Operating Modes
Change the sound characteristic with the push of a button. Triode mode provides smooth sound with rich harmonics and juicy holographic imaging, while Ultralinear mode enhances dynamics and richness, delivering clean, powerful sound and extended capabilities across the frequency spectrum.
Volume Control
A high-quality Japanese ALPS potentiometer ensures smooth, accurate, and reliable volume adjustment.
More Than Just a Headphone Amplifier
HA-6A MK2 features a preamplifier output, turning it into the centerpiece of your audio system. Connect it to external power amplifiers or active speakers to create an exquisite desktop or compact Hi-Fi system.
Custom Design Transformers
Cayin has always insisted on developing high-quality transformers in-house. The custom-made toroidal power transformer features high-purity copper windings that produce less magnetic noise compared to standard transformers.
Precision AudioCapX Capacitors
Effectively isolate DC, enhancing the accuracy and stability of audio signal transmission.
High-Quality Electrolytic Capacitors (Japan)
Deliver fast power delivery and filter out current ripples, reducing sound coloration.
Soft Start Function for 60 Seconds
Provides silent startup with a warm-up delay, allowing the tubes to stabilize fully and deliver the best sound.
