K-05XD (Silver)

K-05XD B (Black)



The K-05XD inherits the philosophy of the historic K-05 series, but has been completely redesigned as a Super Audio CD player completely different from the previous 05 models by completely revamping the design platform. The VRDS-ATLAS transport mechanism "ATLAS 05" is designed exclusively for this model, and the DAC section is a discrete circuit with "Master Sound Discrete DAC" to further refine the music reproduction capability. The Master Sound Discrete Clock for Digital Player, a unique discrete clock circuit for built-in players, incorporates the development results of the master clock Grandioso G1X. The chassis that houses the upgraded ATLAS mechanism, larger circuit blocks, and power supply section is double-layered inside and larger in size. The elegant appearance of this model, which is even closer to the higher-end models, subtly asserts the richness of its content, which is worthy of being called a major innovation. Enjoy the blissful sound of the K-05XD, which is the result of an encounter between the lineage of a famous machine that has captivated music lovers and new technology.
