Overview
It would be easy to see the obvious disc tray and assume the K-03 is another CD-player, but the K-03 was originally marketed more as a DAC with CD capabilities, one step down from Esoteric's flagship “digital source device".
So while digital inputs are limited to coaxial, USB and optical, they feed four 32-bit, AK4399 monaural DACs per channel (the K-01 has an incredible eight per channel), sourced from Asahi Kasei Microdevices. Each dual-mono configured DAC is mounted on a dedicated analog board.
The chassis is constructed in two levels, with five compartments. Each circuit block is housed indivudally to minimize cross-talk. The central transport mechanism is attached directly to the 5mm-thick steel bottom plate and is supported by three patented, resonant-suppressing feet.
The onboard word clock uses a voltage-controlled crystal oscillator (VCXO) with an accuracy of ±0.5 parts per million (ppm); supported by a stabilized power-supply circuit. The clock sync signal is directly delivered to the DACs without passing through the phase-locked loop circuit. The unit also includes facilities for an external word clock via BNC.
The device is SACD capable, using Esoteric's own VRDS-NEO VMK-3.5-10 disc transport. Weighing over 4.5kg by itself, features a duralumin turntable with “micron-level accuracy,” and a 10mm, solid-steel turntable bridge, a coreless, three-phase, brushless-spindle motor driven by strong neodymium magnets and a shaft-sliding type pickup.
Dual proprietary, large-capacity toroidal transformers are employed to manage the DACs and the fully balanced analog circuits, and the digital circuit and transport mechanism. The power circuits and transformers are isolated from the audio board by an internal steel plate.
