Reborn with a new ‘X’ designation, the K-05X commands a central role in Esoteric’s superb lineup of Super Audio CD players, and should really be considered ‘all-new, having been infused with the very essence of our flagship Grandioso models. This new player achieves the very tenets of Esoteric’s design philosophy, conveying to the listener all the emotional expression of music without a hint of stress. With totally revamped audio electronic circuitry, the new ‘X’ model eschew all compromise, and renew the lineage of the K Series.


The unique VRDS-NEO VMK-5 transport mechanism featured in this new player incorporates high-precision turntable that greatly improves reading accuracy by mechanically correcting for disc surface run-out. It's hybrid construction integrates precision-machined aluminum with polycarbonate to help minimize rotational inertia. Formed of high-rigidity BMC (Bulk Molding Compound) and steel, the hybrid turntable bridge also makes a significant contribution to the suppression of rotational vibration and run-out. The transport's spindle motor realizes further improvements in reading accuracy with an advanced servo control that uses rotation detection circuitry. Mechanical operations such as opening and closing the tray and clamping the disc are performed by a unique differential gear system. This proprietary* Esoteric technology ensures exceptionally smooth disc loading operation.


The D/A converter's analog output circuitry features both excellent high-end resolution and natural musical texturing that only high-end components such as  Esoteric's K Series SACD players can offer. Centered around Asahi Kasei's high-end AK4490* 32-bit DAC, this circuitry accentuates the expressive power of these players with 4 parallel/differential circuits and 8 outputs driving each channel—twice that of conventional players in terms of circuit scale—to further enhance sound quality with excellent linearity and low distortion. Arranged in a discreet dual mono configuration, the D/A converters and analog output circuitry are laid out in parallel on either side of the board, and are completely isolated from the digital signal processing circuitry, achieving superb channel separation. Technology developed for the Grandioso C1 Linestage Preamplifier is also employed in the power supply, which features EDLC (Electronic Double-Layer Capacitors). This regulated power supply boasts an astounding total capacity of 500,000μF per channel for exceptional low-frequency sound reproduction.


The K-05X is equipped with a large, high-efficiency, high-powered toroidal transformer, while the K-07X uses a full-sized EI-core transformer. Each is custom-designed to ensure excellent sound quality. High-output power supply circuitry further combines with an array of large capacitors to provide clean and steady power to all circuit blocks.


A high-precision VCXO (voltage controlled crystal oscillator) supplies a highly accurate reference clock signal to the digital circuitry. The K-05X's large, custom-designed VCXO was jointly developed with Nihon Dempa Kogyo (NDK), a leading manufacturer of crystal oscillators. Incorporating an unusually large crystal element, this VCXO realizes both excellent center accuracy (±0.5ppm*) and extremely low levels of phase noise to ensure exceptional sound playback quality.


Connecting the unit to a high-precision master clock generator (G-01, G-02) allows synchronization of the unit's operation with an external clock signal, thereby enabling an upgrade of system sound quality. Compatible with 44.1/88.2/176.4kHz input frequencies, both 10MHz and 22MHz direct master clock linkage* and external clock synchronization are also supported for both digital optical and digital coaxial inputs, as well as when the USB input is used.
