Fully Balanced, Discrete Precision
Moving beyond conventional integrated-chip designs, the H400 MK2 adopts a fully balanced discrete-component architecture with symmetrical signal paths. This carefully engineered design provides greater flexibility in circuit implementation and supports precise, high-quality audio amplification.
Versatile Drive, Flexible Gain
Featuring Low, Mid, and High gain settings, the H400 MK2 adapts to a wide range of headphones, from sensitive IEMs to high-impedance over-ear models. Fine-tune the gain to match your headphones and enjoy a more flexible desktop listening experience.
High-End Components, Precise Amplification
Equipped with 14 OPA1612A op-amps in a parallel configuration, the H400 MK2 is designed to reduce circuit noise and enhance dynamic performance. Combined with ultra-low THD+N of just 0.00006%, it delivers clean signal amplification with exceptional precision.
Refined Design, Thoughtful Protection
Featuring a full-lamination IPS color display and an ultra-compact chassis, the H400 MK2 combines modern desktop aesthetics with practical functionality. Its aerospace-grade all-aluminum body is precision CNC-machined for structural rigidity, heat dissipation, and electromagnetic shielding, while built-in DC, over-voltage, and overload protection adds an extra layer of security.
Clean Power, Stable Performance
Built with a custom low-noise GaN power supply, the H400 MK2 combines high power efficiency with reduced switching noise and stable power delivery. Its carefully designed power system provides reliable support for demanding audio amplification.
