The Esoteric K-03XS Super Audio CD player incorporates the latest advancements in electro-acoustic technology, catering to enthusiasts who seek authentic music reproduction and the highest standards of audio quality. Initially introduced in 2010, the original Esoteric K-03X underwent enhancements in 2014, earning the additional ‘X’ designation. Since its launch, this series of components has set a benchmark in the realm of ultra-high-end digital source players, garnering numerous prestigious awards globally.
The latest iteration, denoted by the ‘Xs’ suffix, represents the third generation of this player, refined through innovative engineering insights derived from the development of the flagship Grandioso K1 model.
The standout feature of the new K-03Xs is its entirely redesigned DAC. This DAC utilizes the cutting-edge architecture originally developed for the Grandioso K1 and is built on an advanced chipset that incorporates four DACs per channel (AK4497 / x 4 DACs per channel). It boasts a more robust power supply, the capability to transmit an analog current signal through the ES-LINK interface, and enhanced resolution for the USB input (DSD 22.5 MHz, PCM 768 kHz / 32-bit). The front panel is equipped with a modern Organic EL matrix display that significantly improves the readability of text.
Additionally, the integrated DD-converter allows for the upsampling of PCM at rates of two, four, and eight times, as well as conversion to DSD prior to digital-to-analog conversion. Users can choose from four digital filters for PCM and one for DSD, all of which are easily switchable via the Mode button on the front panel.
Other notable features include the acclaimed SACD transport, the VRDS-NEO VMK-3.5-10, a powerful power transformer, dual separate power supplies, 34-bit digital-to-analog processing (D/A) that offers 1024 times the accuracy of 24-bit, the innovative ESOTERIC HLCD buffer amplifier, a precision clock generator, and a robust aluminum chassis. The sound quality of the Esoteric K-03XS is particularly remarkable for its smoothness and naturalness, a level of performance seldom achieved by digital technologies. The well-balanced tonal quality, transparency, and detail are inherent characteristics that are expected in this class of technology.
The instruments are showcased prominently on an expansive stage, where the light and nimble high-frequency percussion dances gracefully against a backdrop of deep, diverse bass tones. The grand piano, positioned centrally in both frequency and space, establishes the theme and rhythm, presenting Bach in a contemporary light. With groundbreaking advancements, the Esoteric K-03XS elevates the standard for sound reproduction quality among High End audio players to unprecedented levels.
