Esoteric K-03Xs

Esoteric K-03Xs SACD/CD/dac 
Excellent condition K-03Xs that was owned for less than one year before the client traded it in on a new black K-03XD.  Not for the sonic upgrade, although the new XD series is better, this client just wanted a black unit.   
Includes original box and remote - owners manual should be online and I can potentially print a copy if that is helpful.   
World class SACD/CD player that happens to be able to function as a world class d/a converter also!  multiple digital inputs available to connect your streamer or other digital out sources.   
VRDS-NEO［VMK-3.5-10］

The VRDS-NEO mechanism is used in our flagship model the Grandioso P1 to achieve the ultimate transportation precision. A high-precision turntable is used to rotate CDs and Super Audio CDs, with mechanical correction of surface vibration and dramatically improvese reading precision. The K-03Xs takes this high precision even further with the VRDS-NEO [VMK-3.5-10]. The VS-DD spindle servo driver is used for smooth, high-precision servo control. The transport unit weighs 4.4kg, with a total weight of 11.2kg including the rigid base. The collection of heavyweight parts includes a duralumin turntable and a 10mm-thick steel turntable bridge. These are complemented by high-quality classics from the VRDS-NEO, such as the coreless three-phase brushless spindle motor driven by a strong magnet.

New Dual Mono D/A Converter

The D/A converter section was created based on the latest platform used in the Grandioso K1, with the very finest premium materials and circuit technology added to take it to the highest level of sound quality. The AK4497 32-bit premium DAC device from Asahi Kasei Electronics is combined with a high-quality operational amplifier MUSES8820. The K-03Xs has 4 circuits per channel parallel/differential circuit structure for powerful linearity with minimal distortion. The circuit patterns of the DAC's power section have been further improved, a clean and highly stable power supply. Both the digital and analog circuits have more thorough isolation than previous models, achieving true-to-life playback with outstanding purity and superb sound stage depth.

High-Bit D/A Processing with Outstanding Powers of Musical Expression (PAT. JP6043052)

K-03Xs combine multiple 32-bit DAC chipsets and utilize a high-bit D/A processing algorithm to convert the PCM signal to analog at a high resolution in excess of 32 bits. The K-03Xs supports 34-bit processing. 34-bit processing achieves an astounding resolution that is fully 1,024 times that of 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 Exclusive Output Buffer Delivers Powerful Signal Transmission

The ability to produce comparatively large currents and high slew rates are two of the most important factors that enable an analog output circuit to accurately transmit the wide dynamic range of a music signal without degradation. The K-03Xs offers the ultimate performance as a line driver by adopting high-performance elements with a high current output and exceptionally fast slew rate (2,000V/μs) for excellent response speed. Two of these buffer circuits are employed per channel. By configuring them differentially to drive the XLR outputs and in parallel to drive the RCA outputs, the available instantaneous output current is maximized. By maximizing instantaneous current output, the K-03Xs reproduces the full dynamics of music with breathtaking realism.

"ES-LINK Analog" Method for High Quality Current Transmission

In addition to regular line connections (XLR and RCA), the K-03Xs features Esoteric's new "ES-LINK Analog" transmission method. This is a current transmission method that utilizes the high performance of the HCLD buffer circuit and its enhanced ability to supply high-speed current. This is the ideal analog audio transmission as it is free from signal route impedance, thus fully maximizing the system's potential when connected to a compatible device.*
*A standard balance cable (with an XLR terminal) is used for connections, but the "ES-LINK Analog" method is a proprietary transmission method which can only be used with compatible devices.

Wide Range of D/D Conversion According to Source

In addition to the original Fs playback, this series has a function for up-conversion of PCM digital signals by 2x, 4x, 8x or 16x (maximum 768kHz). It also features a PCM > DSD conversion function using a proprietary algorithm. DSD is up-converted to 22.5MHz. The unit also features a DSD digital filter that can be turned on or off as desired.

Digital Inputs

Three digital inputs (USB, coaxial, and optical) enable connection to a wide range of systems. Coaxial and optical inputs support DSD 2.8 MHz (DoP) input and PCM of up to 192 kHz/24-bit.

USB Audio Interface Compatible
with DSD 22.5MHz, PCM 768kHz/32bit and Asynchronous Transmission

The unit is equipped with a USB port enabling connection to a computer. The driver and playback software (Esoteric HR Audio Player) can be downloaded from the Esoteric website. The unit supports asynchronous transmission and a high sampling playback of DSD 22.5MHz and PCM 768kHz/32bit, and even enables high-quality playback of studio master quality sources. In addition to conventional asynchronous transmission methods, it supports the new Bulk Pet method for an even wider range of tone selection.

High-Precision VCXO Clock

The clock circuit supplies a high-accuracy reference clock signal to the digital circuitry. The Grandioso Custom VCXO (voltage-controlled crystal oscillator) is a high-precision custom clock that utilizes a large crystal element to ensure exceptional sound quality with excellent center accuracy (±0.5ppm) and extremely low levels of phase noise.

Clock Sync Function for Synchronization with External Devices

Connecting the K-03Xs to a high-precision master clock generator such as the G-01X or the G-02X allows synchronization of the unit's operation with an external clock signal, thereby enabling the quality of the system to be further upgraded. Synchronization with an external clock is also available when USB input is used.

Output Modes

The analog audio output can be switched between ES-LINK Analog, RCA, and XLR. Hot 2 or Hot 3 XLR pin assignments can also be selected. Loss in audio quality is eliminated with a non-contact system by performing phase inversion in the digital domain.

Support for Future System Upgrades

RCA (S/PDIF) or XLR (AES/EBU) digital outputs are provided. These allow the player's performance to be upgraded by the addition of a top-end Esoteric D/A converter.
*This circuit can be turned off when digital output is not in use.

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 and 3778108) to effectively suppress vibration. The chassis interior features a double-deck construction. The audio boards are located on the upper layer of the chassis, being isolated from the power supply components on the lower layer, and the power supply wiring has been made as short as possible.
The K-03Xs is equipped with two large 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.

Organic EL Displays

The K-03Xs features smooth-operating, low-consumption electroluminescent (EL) display.

Remote control with brushed aluminum fascia

A wireless remote control is included. (RC-1301)
