VRDS-NEO [VMK-3.5-10]

The VRDS-NEO drive mechanism achieves ultimate levels of transport accuracy. Its high-precision turntable was specially designed to spin Super Audio CD/CD discs, radically improving reading accuracy by mechanically correcting for surface run-out. To provide a comparable level of precision, the K-03X is equipped with the VRDS-NEO VMK-3.5-10 drive, placing Esoteric's superlative music reproduction capabilities within reach of an even greater number of music lovers. The new addition of its VS-DD spindle servo driver further assures smoother high-precision servo control.
With its duralumin turntable and 10mm-thick turntable bridge, the drive mechanism’s massive weight of 24.7 pounds is proof of its robust construction. Other proven VRDS-NEO features include a high-flux-density magnet-driven coreless three-phase brushless spindle motor, high-precision thread feed control, and a shaft-sliding pickup that assures consistently perpendicular laser illumination.


Dual Mono D/A Converters

Allow for extremely accurate digital to analog conversion. This is exemplified by the outstanding linearity and low distortion achieved by the arrangement of 4 individual DAC circuits operated in parallel in each channel. The K-03X uses the same AK4495S* DAC chipset.  To minimize noise, two large toroidal transformers supply power independently to the digital and analog circuits in each channel. The excellent channel separation and stereo imaging of the K-03X's converters provide a mesmerizing musical experience.


34-bit D/A Processing

The K-03X combines multiple 32-bit DAC chipsets and utilizes 34-bit D/A processing algorithm to convert the PCM signal to analog at a high resolution in excess of 32 bits.  34-bit processing achieves an astounding resolution that is fully 1,024 times that of common 24-bit processing. In the digital range, full advantage is taken of high-bit data gradation to minimize calculation errors and provide faithful conversion to analog, thereby attaining outstanding powers of expression with even extremely small music signals.


Esoteric-HCLD*: Esoteric's Proprietary Current-Enhancing Output Buffer Circuit.

The ability to produce comparatively large currents and high slew rates are two of the most important factors to enable an analog output circuit to accurately transmit the wide dynamic range of a music signal without degradation. Two of these buffer circuits are employed per channel. Their high output current capacity and exceptionally fast slew rate (2000V/μs) provide an indication of their excellent response speed. By configuring them differentially to drive the XLR outputs and in parallel to drive the RCA outputs, the instantaneous output current available is maximized. The Esoteric-HCLD circuitry enables the K-03X to recreate the full dynamism of music with a sense of realism that will take your breath away.

Comprehensive D/D Conversion Compatible with wide Range of Sources.

In addition to playback at the original sampling frequency, 2X, 4X and 8X up-conversion of the PCM digital signal is also provided. A range of D/D conversion modes are also available for the PCM format, such as PCM-to-DSD conversion.

Digital Inputs Support DSD (DoP format) and High-Res PCM

Three digital inputs (USB, coaxial, and optical) enable connection to a wide range of systems. Coaxial and optical inputs support DSD in DoP format and high-resolution PCM of up to 192 kHz/24-bit.


USB Support for 2.5/5.6 MHz DSD, 384 kHz/32-bit PCM, and Asynchronous Transmission

The USB input supports asynchronous transmission and rates up to 2.8/5.6 MHz DSD and 384 kHz/32-bit PCM. Esoteric's original PC driver software achieves outstanding playback of even studio-master-quality source files. DoP and ASIO 2.1 are also supported.

High-Precision VCXO Clock

Often considered the heart of a digital player, the clock circuit supplies a high- accuracy reference clock signal to the digital circuitry. Its voltage-controlled crystal oscillator (VCXO) was developed in a joint effort with Nihon Dempa Kogyo (NDK), a major manufacturer of crystal oscillators.  As a high-precision custom clock worthy of the world's leading equipment, this circuit ensures exceptional sound playback quality thanks to an exceptionally large crystal element with excellent center accuracy (±0.5 ppm*) and extremely low levels of phase noise.

Output Modes

The analog audio outputs can be switched between RCA, XLR, and OFF. Hot 2 or Hot 3 XLR pin assignments can also be selected.

Chassis Construction and Parts Layout

The VRDS-NEO transport mechanism is positioned in the center of the unit, directly attached to the 5 mm-thick steel chassis bottom, and is supported at three points by Esoteric's proprietary pinpoint feet (Patent No. 4075477) to effectively suppress the effects of vibration on the turntable mechanism. The chassis interior features a double-deck construction with five compartments. Each circuit block is isolated within its own compartment to minimize interference between circuits. Two separate audio boards for each channel are positioned nearest the rear terminals. The audio power circuitry and power transformers are also isolated from the audio boards, and the power supply wiring has been made as short as possible to minimize the influence of magnetic flux leakage, vibration, and the like.
The K-03X is equipped with two large-capacity toroidal transformers: one for the analog circuitry and the other for the digital/mechanism drive circuitry. This design provides ideal power supply capability to all circuit blocks without interference.
