The ultimate Network x DAC
only ESOTERIC could achieve
An all unique circuit design called "Master Sound Discrete DAC",
together with a further refined sound quality Network Module as core
technology result in the ultimate Network Audio Player/DAC, the N-01XD.
The outcome of ESOTERIC's passion that strives for the original master
sound.
Esoteric's goal was to assemble a careful selection of rigorously tested
discrete components into a complete circuit that could perfectly
reproduce all the dynamics and energy of music, which is simply
unattainable using ordinary integrated chips. Esoterics top engineering teams
put their pride on the line to design and produce a quality of sound
that can only be found in our Master Sound Discrete DAC discrete D/A
converter.
Luxurious Materials and Powerful Current Output
The N-01XD’s Master Sound Discrete DAC is the most revolutionary
two-channel stereo DAC circuit in ESOTERIC’s history, and is based on
the original circuit developed for the Grandioso D1X Monoblock D/A
Converter. As an extension of the D1X’s design philosophy, an abundance
of luxurious materials have been invested in the construction of
N-01XD’s Master Sound Discrete DAC, including 32 separate elements for
each channel. Each of these 32 elements, including such key components
as a clock driver, logic circuitry, capacitors and resistors, are kept
independent to ensure the purest output with virtually no loss of
musical energy.
Advanced Digital Processing Capability
The N-01XD includes ESOTERIC’s exclusive Delta-Sigma (ΔΣ) modulator
supporting 64-bit/512Fs audio frequency sampling. To perform D/A
conversion on par with its excellent DSD and PCM characteristics,
separate FPGA* digital processing algorithms were developed for each
conversion process. This enables the N-01XD to extract the optimum sound
quality from CDs, Super Audio CDs, and networks.
* FPGA: Field-Programmable Gate Array
Unique ESOTERIC-HCLD* Output Buffer Circuit with Enhanced Current Transmission
The N-01XD’s ESOTERIC-HCLD output buffer amplifier boasts an
astonishing high-speed slew rate (response speed) of 2,000V/µs. Current
transmission and speed—the most important factors in the design of any
analog output circuit—have been pushed to the limits, while the array of
EDLC** super capacitors used in the buffer circuit’s power supply
provide a staggering capacitance of 250,000μF per channel for solid bass
support and exceptional reproduction of all the dynamism of music
coupled with a sense of realism that is truly breathtaking.
*HCLD: High Current Line Driver
**EDLC = Electric Double-layer Capacitor
High-Quality ES-LINK Analog Current Transmission
In addition
to its standard XLR and RCA line connections, the N-01XD is also
equipped with Esoteric’s own ES-LINK Analog current transmission system.
Taking full advantage of the robust stream of current supplied by its
HCLD buffer circuitry makes the N-01XD less susceptible to the
detrimental effects of signal path impedance, ensuring more pure and
powerful signal transmission that maximizes system potential to deliver
outstanding analogue audio output transmission when connected to
comparable components.
Transport Connections for Super Audio CD playback
The N-01XD supports Esoteric’s proprietary ES-LINK digital wideband
transmission standard. An Esoteric transport can also be connected using
either two HDMI cables or a single XLR cable to enable playback of
Super Audio CDs.
*ES-LINK is an ultra-wideband digital interface developed exclusively by
Esoteric. Like our flagship Grandioso D1X Monoblock D/A Converter, the
N-01XD’s ES-LINK has also been upgraded to Version 5 to support
wide-range transmission using two HDMI cables (Max: 22.5MHz DSD or
768kHz/48-bit PCM). The HDMI multi-cable configuration is used for fully
balanced audio data, LR clock, and bit clock signal transmission. In
contrast to regular digital transmission, no processing is required for
signal modulation at the sending side or for demodulation at the
receiving side, thus allowing a significant reduction in the DAC’s
digital processing load to help realize pure digital signal transmission
with near perfect optimization.
Full MQA Support
The N-01XD is also capable of MQA decoding for all digital input
sources. In addition to conventional network input, MQA-CD playback is
also possible when used in combination with a CD transport.
Network Audio
With network audio, you can realize the opulent dream of full access
to all your music with superior sound quality from the comfort of your
listening position. All that is required besides the audio system is a
regular home LAN (such as a Wi-Fi router), tablet or smartphone, and a
NAS (Network Attached Storage) device for storing your music library.
With these components, you can easily begin a life of relaxing music
enjoyment with uncompromising quality.
The N-01XD features noticeable improvements in network playback quality,
including the latest developments in network modules that supports
22.5MHz DSD and linear power supply technology without any switching
elements.
Compatible with a Wide Range of Audio Sources
The N-01XD is compatible with 22.5MHz DSD, 384kHz/32-bit PCM playback
and a host of other formats (DSF, DSDIFF, FLAC, Apple Lossless, WAV,
AIFF, MP3, AAC and MQA). Gapless playback capability is also offered in
all lossless formats.
ESOTERIC Sound Stream
Esoteric Sound Stream is an Apple iOS/Android network playback app
for smartphones and tablets designed with an emphasis on both sound
quality and intuitive operability. Musical tracks can be easily selected

connection of up to two large-capacity USB storage devices (USB flash
drive, external USB HDD/SDD, etc.) for use as a music server. This
allows easy music playback even without a separate NAS for people who
find NAS configuration to be too complicated and troublesom.
(*) HDD/SDD cannot be installe inside the N-01XD unit itself.
Equipped with Four Powerful Independent Power Suppllies
The key to the powerful and deep, rich sound provided by the N-01 and
D-02X lies in their high-performance power supplies. The N-01XD
features significant enhancements to its power supply to ensure it
delivers even more robust, lifelike sound.
Its built-in D/A converter features a total of four independent toroidal
power transformers, one each for the right and left channels, digital
circuits, and network module. The DAC's regulator utilizes a
low-feedback DC regulator for minimizing feedback in a discrete
configuration that uses no integrated circuits, but instea adopts
technology obtained in the development of the Grandioso P1X Super Audio
CD Transport and D1X Monoblock D/A Converter. The result is a powerful,
expansive sound.
Network Module Features High-Sound-Quality Linear Power Supply
Thanks to recent breakthroughs in the development of our network
transports, the network module uses a new power supply designed with
linear elements customized for audio use instead of a regulated
switching power supply. Combined with its high-capacitance filter
capacitors, Schottky barrier diodes, EDLC (Electric Double-Layer
Capacitor) super capacitors boasting a capacitance of 2,333,333μF, and
other high-end components, this enables the N-01XD to deliver
dramatically improved sound quality.
Grandioso Custom VCXO* II
The N-01XD also includes the same Grandioso Custom VCXO II
high-presicion clock developed for the P1X and D1X, which features
extremely low levels of phase noise and excellent centering accuracy
(±0.5ppm). The N-01XD's clock output enables high-precision clock
synchronization using the Grandioso Custom VCXO II as a master unit by
simply connecting it to a transport with a clock input port. An external
Grandioso G1 or G-01X Master Clock Generator can also be connected to
synchronize interna circuits with a 10MHz clock that rivals atomic
clocks in its precision, thus realizing even higher levels of sound
quality. USB input and network playback can also be synchronized with
the external clock.
*VCXO: Voltage-controlled crystal oscillator
USB Audio Interface Supports 22.5MHz DSD
and Asynchronous Transmission
The N-01XD is further equipped with USB-B port for connecting to a
computer. The driver and ESOTERIC HR Audio Player (music player
application) can be downloaded for free from the ESOTERIC website. The
audio interface supports high sampling playback at 22.5MHz DSD and
asynchronous transmission for enabling high-fidelity playback from even
studio master quality sources. In addition to its USB ports, three types
of digital input ports(XLR x 1, coaxial x 2, optical x 1) have also
been provided for connection to a wide range of digital devices.
Highly-Rigid Chassis Design
The N-01XD features a highly rigid chassis design incorporating
thick, dual layer aluminum and steel panels and a double-deck interior
structure that both suppresses interfence between circuits and
drastically shortens power supply wiring to achieve the ultimate
in sound quality. Additionally, every slot and groove in the chassis has
been precisely laser-machined to effectively reducd vibration. The
chassis' entire 5mm-thick steel bottom panel is supported by our own
ESOTERIC pinpoint feet (patent No;JP4075477,JP3778108) to ensure
complete mechanical grounding that further protects the unit against the
effects of vibration.
Semi Floating Top Panel
The enclosure's top panel utilizes a screwless semi-floating
structure that further contributes to the N-01XD's open and expansive
sound.
