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, results in the ultimate Network Audio Player/DAC, the N-01XD. The outcome of ESOTERIC's passion is striving for the original master sound.
 
Our 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. Our 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.
 
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.
 
Music Server Function(*)
The N-01XD has two USB-A ports, one each on its front and rear panels, that enable 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 troublesome.
(*) HDD/SDD cannot be installed inside the N-01XD unit itself.
 
Equipped with Four Powerful Independent Power Supplies
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.

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 interference 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 reduced vibration. The chassis' entire 5mm-thick steel bottom panel is supported by our own ESOTERIC pinpoint feet 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.
