Cayin HA-300 MK3 Flagship tube headphone amp

Cayin proudly introduces the HA-300 MK3, the latest generation of our 300B tube headphone and speaker amplifier—crafted for listeners who demand the very best in musicality, refinement, and versatility.

As the third-generation evolution of one of Cayin’s most celebrated amplifier platforms, the HA-300 MK3 takes our pure Class A, single-ended triode design philosophy to a new level. With comprehensive upgrades in circuit design, transformer performance, power supply implementation, premium component selection, and industrial finishing, the HA-300 MK3 delivers an even more accomplished and immersive listening experience.

From the first note, the HA-300 MK3 reveals the unmistakable charm of 300B amplification: rich tonal density, natural warmth, expansive soundstage, and deeply engaging musical expression. At the same time, its upgraded architecture provides improved stability, lower noise, and greater adaptability across a broader range of headphones—from highly sensitive in-ear monitors to demanding high-end full-size headphones. With built-in speaker output capability, the HA-300 MK3 also extends its appeal beyond personal audio, offering true flexibility for discerning tube enthusiasts.
