Digital Source Device

VRDS-NEO, 4-DAC (32BIT)/CH, 192/24 HIGH-REZ INPUTS, ADVANCED CLOCKING

INTRODUCTION

ESOTERIC releases the K-01, the flagship model of our all-in-one advanced D/A converter and Super Audio CD/CD player series, capitalizing on ESOTERIC’s state-of-the-art technology and derived from our award winning P-01/D-01 series separates. It has been seven years since the debut of the original X-01, with its high-precision and high-rigidity VRDS-NEO SACD/CD transport mechanism. The X-01/X-03 series, which have stayed at the top of ESOTERIC’s all-in-one SACD/CD player lineup, have been completely updated and make their debut as the all-new “K” series in November 2010.

The design concept of the K series is extremely clear and simple -- a 2-channel D/A converter and stereo player that gives a stress-free musical experience, without adding or removing anything from the original source material. All aspects of the design and engineering process for the K series had extremely tough requirements to further advance ESOTERIC's top technology. Design and engineering was completed applying all of ESOTERIC’s know-how in mechatronics technology, state-of-the-art audio technology, and evolutionary materials including DAC implementation, for which cost was not a consideration. The K series is committed to advancing the “state of the art” for the 2 channel audio purist, for both high resolution audio files and disc based audio playback applications.

The K-03 is equipped with our new VRDS-NEO “VMK-3.5-10” mechanism, which has further advanced substantially beyond existing VRDS models, and a dual mono configuration of 32-bit monaural D/A converters with four parallel/differential DAC circuits per channel. The analog audio circuit has a separate power transformer. The on-board high-precision clocking circuit has also been advanced. Three sets of 192 kHz/24-bit digital inputs supporting the most advanced high-sampling digital sources are also built-in. USB driver software supports 192 kHz/24-bit asynchronous transmission for connecting with a PC.

The K-03 is a high performance model that follows the philosophy of the top-end all-in-one K-01 digital source, 2-channel playback device.

K-03 specifications

Esoteric K-03 is a high-performance digital-to-analog converter (DAC) that embodies the brand's commitment to audio excellence. Designed for audiophiles and music enthusiasts, the K-03 combines state-of-the-art technology with exceptional build quality to reproduce sound with unparalleled clarity and precision.

At the heart of the K-03 is its advanced D/A conversion technology. Utilizing a sophisticated, proprietary R2R ladder design, this DAC achieves remarkable linearity and dynamic range. The K-03 supports high-resolution audio formats, including DSD and PCM, allowing it to handle files up to DSD256 and PCM 384kHz/32-bit. This capability ensures that even the most nuanced details in audio recordings are captured, providing listeners with an authentic and immersive experience.

The K-03 incorporates Esoteric's unique "Master Clock" technology, which minimizes jitter and enhances timing accuracy. This results in a more stable and cohesive soundstage, making it easier to identify individual instruments and vocals. Additionally, the device features dual differential outputs, providing balanced and unbalanced connectivity options to suit various setup configurations.

Another significant aspect of the K-03 is its digital input versatility. It includes USB, coaxial, optical, and AES/EBU connections, ensuring compatibility with a wide range of digital sources. The USB input utilizes a high-performance asynchronous transfer mode, reducing latency and preserving audio quality. The K-03 also supports various digital filters, giving users the option to tailor the sound to their preferences.

The construction of the K-03 is equally impressive. Its robust chassis is designed to minimize interference and vibration, which can compromise audio quality. The device features meticulously selected components, from capacitors to resistors, ensuring that each element contributes to the overall sonic performance.

For those who value aesthetic appeal alongside functionality, the K-03 comes with a sleek, modern design that fits seamlessly into any audio system. Its user-friendly interface makes it easy to navigate through settings and options, enhancing the overall user experience.

In conclusion, Esoteric K-03 is a remarkable DAC that showcases cutting-edge technology along with exquisite craftsmanship. Its combination of advanced features, support for high-resolution formats, and exceptional sound quality make it a standout choice for discerning audiophiles seeking to elevate their listening experience.
