Cayin HA-300 MK3 Tube Headphone and Integrated Amplifier

Description

The new Cayin HA-300 MK3 builds on the acclaimed architecture of the MK2 with major advances in components, circuitry, craftsmanship, and industrial design. From sonic refinement to day-to-day usability, every detail reflects Cayin's ongoing pursuit of acoustic excellence.

As the third-generation model in the HA-300 series, the HA-300 MK3 builds on the acclaimed architecture of the MK2 with major advances in components, circuitry, craftsmanship, and industrial design. From sonic refinement to day-to-day usability, every detail reflects Cayin's ongoing pursuit of acoustic excellence.

The HA-300 MK3 continues the series' classic single-ended pure Class A tube amplifier design, combining premium tubes with a newly upgraded circuit to achieve an exceptional balance of musicality and technical performance.

The HA-300 MK3 employs two JJ GZ34 / 5AR4 tubes and an upgraded tube rectification circuit delivering improved efficiency while preserving the distinctive appeal of tube-based power supply design.

The JJ 6SN7 tubes provide low noise and high resolution, enabling accurate voltage gain and excellent detail retrieval while laying a clean foundation for the subsequent amplification stages.

Known for their warm, richly textured character, the Genalex Gold Lion PX300B tubes deliver a full, delicate midrange, smooth, transparent highs, and deep, well-controlled bass.

The HA-300 MK3 features the physically separated power supply and main amplifier chassis, providing cleaner energy delivery and improved isolation from interference. The voltage amplification stage incorporates a low-noise regulated circuit with independent staged power delivery, preserving the integrity of the original audio signal. 

In addition, the HA-300 MK3 has been specially optimized for IEM compatibility, making it suitable for a much wider range of headphones than before.

The updated transformer housing design removes the previous aluminum decorative plates, resulting in a cleaner, lighter visual appearance and improving heat dissipation. For improved wear resistance and reduced fingerprint visibility, the HA-300 MK3 chassis is finished with a fine sandblasted texture. A newly designed family-style tube cage replaces the previous design, providing stronger protection.
