Esoteric K-07X CD/SACD Player and DAC
Sublime-Sounding Esoteric K-07X SACD/CD Player and DAC Features Advanced VOSP Transport and VCXO Clock: Huge Power Supply, 34-Bit D/A Processing, USB Support for 11.2MHz DSD Are Standard
Receiving significant updates for 2015, the Esoteric K-07X CD/SACD player and DAC owes much of its cutting-edge sonic prowess to its VOSP, a state-of-the-art transport mechanism that guarantees the laser axis always remains at the center of the data track for impeccably accurate reading. Comprised of steel, the anti-resonance design is built to withstand earthquakes. A huge toroidal transformer, five separate digital filters, and an enhanced voltage-controlled crystal oscillator clock generator complement K-07X's 34-bit D/A processing. You can sit back and relish your music the way it's meant to be heard knowing that four AK4490 32-bit balanced DACs convert high-res 34-bit PCM to analog for optimal dynamics, expressiveness, and detail. K-07X even touts USB support for 2.5/5.6/11.2MHz DSD and up to 32-bit/384k PCM. Read more about the progressive technology and unsurpassed parts below, but understand that this jewel brings reference-class subtlety, transparency, air, extension, and dimensionality to every disc you play. 100% Music Direct Guaranteed.
A State-of-the-Art Transport: VOSP (Vertically Aligned Optical Stability Platform)
K-07X touts Esoteric's VOSP (Vertically Aligned Optical Stability Platform), which features a specially designed shaft-mounted laser pickup assembly. The latter ensures the laser optical axis is always at the center of the data track for highly accurate reading. VOSP mechanism is rigidly clamped by a steel plate and a large diameter stabilizer made of 8mm-thick steel for superior anti-resonance and anti-vibration properties.
Refined Dual Mono D/A Converters Achieve Premium Channel Separation and Power
The D/A converter's analog output circuitry features excellent high-end resolution and natural musical texturing. Centered around Asahi Kasei's high-end AK4490 32-bit DAC, this circuitry accentuates the player's expressive power with four parallel/differential circuits and eight outputs driving each channel – twice that of conventional players – 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 completely isolated from the DSP circuitry, achieving superb channel separation.
34-Bit D/A Processing Translates Into Optimal Musical Expressiveness
Employing a 34-bit D/A processing algorithm with an encoding resolution that is an astounding 1,024 times greater than that of 24-bit encoding, multiple 32-bit DAC devices are combined to convert the high-resolution 34-bit PCM signal to analog. In the digital range, high-bit data gradation minimizes calculation errors and provides faithful conversion to analog, attaining outstanding powers of expression with even extremely small music signals.
A Power Supply to Write Home About: Incorporates High-End EDLC Technology
K-05X is equipped with a large, high-efficiency, high-powered toroidal transformer custom-designed to ensure excellent sound quality. Technology developed for Esoteric's Grandioso C1 preamplifier is also employed, and 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. High-output power-supply circuitry further provides clean, steady power to all circuit blocks.
Proprietary Esoteric-HCLD Type 2 Current-Enhancing Output Buffer Circuit
Providing excellent current transmission capability as well as a strong drive output, K-05X employs Esoteric-HCLD Type 2 buffer amplifier circuitry first used in such high-end models as Esoteric's C1 preamplifier. Two buffer circuits are installed per channel and configured differentially to drive the XLR outputs and in parallel to drive the RCA outputs.
High-Precision VCXO Clock for Serious Accuracy and Sonics
K-05X's high-precision VCXO (voltage controlled crystal oscillator) supplies a highly accurate reference-clock signal to the digital circuitry. K-05X's large, custom-designed VCXO is jointly developed with Nihon Dempa Kogyo (NDK), a leading manufacturer of crystal oscillators. Incorporating an unusually large crystal element, the VCXO realizes both excellent center accuracy (±0.5ppm) and extremely low levels of phase noise to ensure exceptional sound quality.
External Clock Sync Ability
Connecting K-05X to a high-precision master clock generator (G-01, G-02) allows synchronization of its 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 the 10MHz and 22MHz direct master clock linkage and external clock synchronization are supported for both digital optical and digital coaxial inputs, as well as when the USB input is used.
