Esoteric K-01XS: Ultra-High End Super Audio CD player

The Esoteric K-01XS Super Audio CD player incorporates cutting-edge electro-acoustic technologies and is designed for enthusiasts who seek true music fidelity, as well as for discerning audiophiles. The original K-01 model was unveiled in 2010, and it underwent enhancements in 2014, earning the designation ‘X' in its name. Since its launch, this series of components has established itself as a benchmark in the realm of ultra-high-end digital sources, garnering numerous prestigious awards globally.

The latest iteration of the player, designated with the Xs suffix, marks the third generation of this model, enhanced through cutting-edge engineering insights gained from the flagship Grandioso K1. A standout feature of the new Esoteric K-01XS is its entirely redesigned DAC, which utilizes the innovative architecture originally crafted for the Grandioso K1. This is paired with an advanced chipset (AK4497 with eight DACs per channel), a more robust power supply, the capability to transmit an analog current signal via the ES-LINK interface, and superior specifications for the input digital stream on the USB interface (DSD – 22.5 MHz, PCM – 32 bit / 768 kHz).

The front panel now features a modern Organic EL display that enhances the clarity of the text. Other significant attributes remain unchanged, including the acclaimed in-house SACD transport VRDS-NEOVMK-3.5-20S, a powerful power transformer, four dedicated power supplies, and 35-bit digital-to-analog (D/A) processing, which offers 2,048 times the precision of 24-bit. Additionally, it includes the innovative ESOTERIC HLCD buffer amplifier, a high-precision clock generator, and a super-rigid aluminum chassis. With these groundbreaking advancements, the ESOTERIC K-01XS SACD player elevates the standard for sound reproduction quality in high-end audio equipment.

The K series incorporates the full spectrum of ESOTERIC's expertise in mechatronics and audio technology, utilizing cutting-edge materials, including the DAC, without regard for component costs. This series elevates the experience of 2-channel playback to unprecedented heights, excelling in both high-resolution audio file reproduction and disc playback. The Esoteric K-01XS is designed to satisfy the most discerning music enthusiasts and audio purists, serving as a premier digital source and player within a single unit.
