Engineered for Pure Performance Designed for uncompromising sound quality, the HA-6A MK2 features a dual-chassis design that isolates the power supply for lower noise and greater clarity. Each amplification stage is independently regulated to minimize interference, while a custom silver-plated copper umbilical cable ensures efficient, lossless current delivery. Upgraded Amplification Circuitry The headphone amplification circuit has been upgraded with high-quality components, delivering breakthroughs in both core performance and user experience. With wide compatibility and enhanced driving power, it can accommodate and power a greater variety of headphones. Tube Complement – Single-Ended Class A Power Amplification Utilizing a matched pair of Genalex KT88 tubes, faithfully reproducing the natural tonality of music with rich, engaging sound. Impedance Matched Headphone Output In-house output transformers provide impedance-matched outputs for low (8–64Ω), mid (65–250Ω), and high (251–600Ω) 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 jack suits sensitive IEMs with reduced output and improved S/N performance. Additional Features: Dual Operation Mode Change your sound signature with the flip of a switch. Triode mode offers a smooth sound with rich harmonics and lush, holographic imaging. Ultralinear Mode improves the dynamics and punch, with a clean authoritative sound and enhanced extensive on both ends of the frequency spectrum. Volume Control A Premium Japanese ALPS potentiometer delivers smooth, precise and reliable volume adjustment. More Than a Headphone Amp The HA-6A MK2 introduces a dedicated PRE-OUT output, elevating it from a headphone amplifier into the centerpiece of your audio system. Connect it to external power amplifiers or active speakers to create a refined desktop or small-scale Hi-Fi setup. In-House Developed Transformers Cayin has always insisted on developing high-quality transformers in-house. The custom toroidal power transformer uses a high-purity copper winding design, which produces lower magnetic noise compared to standard transformers. AudioCapX Coupling Capacitors Accurately isolate DC current, improving the precision and stability of audio signal transmission. High-Grade Electrolytic Capacitors (Japan) Provide fast power delivery and filter out ripple current, reducing sonic coloration. 60-Second Soft Start Function Ensures silent startup with a delayed warm-up, allowing the tubes to fully stabilize and deliver the best sound performance.
