VRDS-NEO “VMK-3.5-20S” transport mechanism


 ESOTERIC’s
proprietary VRDS-NEO transport mechanism uses a high-precision
turntable for
spinning Super Audio CD/CD discs, improving read precision
by mechanically correcting for surface run-out. This is a comprehensive
compilation of ESOTERIC’s high-end mechatronics technology. The K-01
uses an evolutionary version of the mechanism configuration adopted for
the P-03 SACD/CD transport and now includes the VRDS-NEO “VMK-3.5-20S.”
This new VRDS mechanism includes further refinements in the design of
the driver circuit. In addition, the disc tray loader now includes a
shutter mechanism, designed to reduce extraneous noise and airborne
contaminants from entering or degrading the electromechanical operation
of the system.

 The VRDS-NEO “VMK-3.5-20S” is a new high-quality mechanism
using a set of ceramic ball spindle bearings. A duralumin turntable with
micron-level accuracy and a 20 mm steel turntable bridge are used,
resulting in a total weight of 5.2 kg (11.5 lbs). Additionally, the
proven features of the VRDS-NEO, such as the strong
neodymium-magnet-driven coreless three-phase brushless spindle motor,
the thread feed control, (which has evolved from the philosophy of the
P-0), and the shaft-sliding type pickup, where the laser beam
consistently illuminates the disk perpendicularly, are all inherited by
the K-01.






New VS-DD spindle servo driver circuit


 The
driver circuit of the transport mechanism was newly designed
specifically for
audio playback, to accomplish smoother and higher-accuracy
servo control. The VS-DD (VRDS Spindle Discrete Driver), a newly
designed discrete amplifier circuit, is used to drive the spindle motor,
which is the core of the VRDS-NEO”VMK-3.5-20S”.

 Special proprietary toroidal transformers are also used in
the power supply. The discrete amplifier circuit optimizes the power
supply output to the motors, to realize a smoother and more refined
spindle drive. Additionally, a separate power supply is used for each
power-consuming spindle motor, to eliminate any impact on the audio
circuit and to achieve outstanding performance. This level of
performance approaches the quality of a separate transport and DAC
reference system.






VCXO high-precision clock


 A
newly designed high-precision clock is implemented to achieve the
highest level of sound quality for an all-in-one digital player. A VCXO
(voltage controlled crystal oscillator) of +/- 0.5 ppm (*2) that uses a
large crystal is deployed in the K-01, which is very advantageous for
advanced sound quality.

 Additionally, a stabilized power supply circuit improves
the stability of clock circuit operation. When using the K-01 without
using an external WORD clock, the high precision audio clock sync signal
generated by the VCXO is directly delivered to the D/A converter,
without passing through the PLL circuit. This enables higher-quality
reproduction that is a step ahead of standard designs. This also
substantially reduces any audible jitter when transmitting audio signals
to achieve high-speed and high-quality reproduction inclusive of a very
dramatic presence and acoustic delicacy.

High-quality discrete buffer circuit with a high voltage power supply


 A discrete buffer
output circuit with a high voltage power supply of +/- 22 V has been
deployed for the analog audio output, following the technology used in
the D-01. Full use is made of the exceedingly high drive capability and
slew rate to provide a stress-free playback capability for various
signals, from miniscule signals to high-power output. These powerful
discrete buffer output circuits are laid out symmetrically for each of
the hot/cold signal lines to construct a rich and fully balanced
configuration for XLR audio outputs. Additionally, a parallel buffer
output configuration is implemented to switch the buffer amplifier to a
parallel configuration, when RCA audio outputs are used. These
enhancements provide advanced circuitry with the best sound quality for
each of the balanced and unbalanced signal outputs.






Four types of digital filters and digital filter “Off” mode


 The K-01 features
four types of digital filters for PCM signal processing. In addition to
two types of FIR digital filters that have a reputation for outstanding
sound quality, two types of short delay digital filters are featured.
These filters, often referred to as apodizing filters, eliminate the
pre-echo and ringing effects in the impulse waveform to reproduce the
audio signal as a more nature and precise sound, void of the artifacts
often associated with CD recording. The Digital Filter Off mode, which
bypasses all 4 of the digital filters, is also provided. You can select
any of the digital filters or the off mode according to your preference.






Three digital input systems to support a high sampling rate


 Even when you use
the K-01 as a discrete D/A converter for a high-sampling-rate source,
the K-01 makes the most of the astonishing quality of its 32-bit dual
mono D/A converters. The K-01 features three systems of input (USB,
coaxial and optical), and these digital inputs support
high-sampling-rate sources up to 24 bit/192 kHz.






USB
input supporting asynchronous transmission and 24 bit/192 kHz sources
enables high-quality reproduction of music stored on a PC


High-sampling-rate
sources of studio master quality can be input at their original
resolution, by connecting the K-01 to your PC through a USB port. To
ensure a precise high-end design for the USB connection, ESOTERIC
developed proprietary driver software (the driver software can be
downloaded from the ESOTERIC website). The USB input supports
high-quality asynchronous transmission and the input of
high-sampling-rate sources to 24 bit / 192 kHz. Three transmission
modes, including two types of high-speed transmission (including
asynchronous transmission), and the standard full-speed mode, are also
provided to enhance compatibility with a wide variety of PCs and
operating systems.

 Additionally, an Esoteric USB isolator, isolates the power
and signal paths from the USB input system. This isolator eliminates
interference from external devices, including the PC, to clearly
reproduce high-resolution music files without loss of fidelity.
* Note: Reproducible formats depend on the music player capabilities installed on the PC.
