The lineage of high-end digital audio follows the evolutionary steps of ESOTERIC digital players. This began with the first generation P-1/D-1 model in 1987, which made the revolutionary step of including a VRDS mechanism, and was followed by models featuring the ultimate in engineering and craftsmanship, such as the P-70/D-70 in 2001 and the P-03/D-03 in 2005. In the year 2016 these models were succeeded by the superior P-02X/D02X. And now three decades after the birth of the ESOTERIC brand, we have the P-05X/D-05X. The P-05X/D-05X inherits the successful results of the P-02X/D-02X to give birth to a new milestone in high-end audio which is suitable for the start of the next three decades.
In the Footsteps of ESOTERIC's Most Advanced Grandioso Technology
Both the P-05X and D-05X have been newly equipped with ESOTERIC's state-of-the-art ES-LINK4, which provides high-accuracy digital transmission of both DSD and ultra-wideband 352.8kHz/48-bit PCM by way of its HDMI cable connections. A core feature of the Grandioso P1/D1 digital source system, and developed in line with ESOTERIC's ‘Pure D/A’ concept, ES-LINK4 performs the major portion of digital signal processing on the transmission side to significantly reduce the processing load on the D/A converter in pursuit of the ultimate in sound quality.
The Expressive Power of 34-bit D/A Processing
The D-05X utilises a 34-bit D/A processing algorithm to convert the PCM signal to analog. This 34-bit encoding provides an astounding level of digital resolution that is fully 1,024 times that of 24-bit encoding, and quadruple that of the original D-05 model. Taking advantage of the delicate tone realised by this high-bit data minimises calculation errors for outstanding expression of even the most subtle musical signals.
High-Precision VCXO Clock Technology
A high-precision custom VCXO (voltage controlled crystal oscillator) supplies a highly accurate reference clock signal to the digital circuitry. Incorporating an unusually large crystal element, this custom VCXO realizes both excellent centre accuracy (±0.5ppm) and extremely low levels of phase noise to ensure exceptional sound playback quality.
High-Accuracy Clock Synchronisation
A BNC cable connects the D-05X to the P-05X to provide a master clock sync signal for synchronised playback with minimised jitter. ESOTERIC's proprietary Direct Master Clock Link* synchronises the two units while eliminating the need for Phase-Locked Loop (PLL), enabling clear and accurate stereo imaging and crisp sound quality. The system can be further upgraded with the addition of an optional high-accuracy external Master Clock Generator and supports a wide range of frequencies including master clocks (22MHz/10MHz) and word clocks (44.1kHz/88.2kHz/176.4kHz).
All major components updated from the original model to bring a new level of superiority
The P-05X is a brand new transport that brings together all the knowledge built up by ESOTERIC during the 10 years since the original P-05 model was released, and almost all of its components have been updated from the original model. This model includes the world-renowned VRDS-NEO VMK-5 drive mechanism and its digital circuit and clock circuit adopt technology developed for the Grandioso P1 and P-02X. The luxurious power supply circuit with large toroidal transformers has been enhanced to obtain even higher audio quality. Functionality has also been upgraded with support for ES-LINK4 digital transmission. By following the same design principles as higher end models, the chassis of the P-05X has been made more rigid and the exterior has evolved to emphasize an elegant round shape.
