New Technologies of the P-02X & D-02X Audio Systems
Both the P-02X and D-02X 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 36-Bit D/A Processing
Like the Grandioso D1, the D-02X utilizes a 36-bit D/A processing algorithm to convert the PCM signal to analog. This 36-bit encoding provides an astounding level of digital resolution that is fully 4,096 times that of 24-bit encoding, and double that of the 35-bit model on which it is based. Taking advantage of the delicate tone realized by this high-bit data minimizes calculation errors for outstanding expression of even the most subtle musical signals.
New Dimensions in Isolated Clock Technology
Widely considered to be the core of any high-end digital player, the clock circuit provides a high-accuracy reference signal for digital circuitry. The clock circuits featured in the P-02X and D-02X are completely isolated from all other circuits, including power source and ground, enabling a pure clock signal to be supplied to the system. The clock's voltage controlled crystal oscillator (VCXO) was specially developed for Esoteric's Grandioso line in a joint effort with Nihon Dempa Kogyo (NDK), one of the world's premier manufacturers of crystal oscillators, for a high-precision custom clock worthy of the world's finest audio equipment. Its extremely low levels of phase noise combine with a large-scale crystal element to ensure exceptional sound reproduction quality.
High-Accuracy Clock Synchronization
A BNC cable connects the D-02X to the P-02X to provide a master clock sync signal for synchronized playback with minimized jitter. Esoteric's proprietary Direct Master Clock LINK* synchronizes 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 G-01 Rubidium Master Clock Generator, and supports a wide range of frequencies including master clocks (22MHz/10MHz) and word clocks (44.1kHz/88.2kHz/176.4kHz).
