Bringing out all the dynamics and energy of music. Unattainable by integrated chips, our goal was to assemble carefully selected and tested discrete components into a complete circuit that could perfectly reproduce all the dynamics and energy of music. Our top engineering teams put their pride on the line to design and produce a quality of sound that can only be found in the 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 monaural D/A converter.
As an extension of the D1X’s design philosophy, a luxurious volume of materials have been invested in the construction of N-01XD’s Master Sound Discrete DAC. For example, it features 32 separate elements for each channel. Key components such as a clock driver, logic circuit, and capacitors and resistors, are kept independent for each of these 32 elements to ensure the purest output without no loss of musical energy.
Powerful Digital Processing Performance
Employing an ESOTERIC’s unique ΔΣ modulator that allows 64bit/512Fs input, and Digital-to-Analog processing with the FPGA* Digital-processing Algorism optimized for DSD and PCM formats respectively, the N-01XD delivers super high-quality sound regardless source, a Super Audio CD, a CD or Network.

Unique ESOTERIC-HCLD Output Buffer Circuit with Enhanced Current Transmission
The ESOTERIC-HCLD *1 output buffer amplifier boasts an amazingly high-speed slew rate (response speed) of 2,000V/µs. Current transmission and speed—the most important factors for an analog output circuit—have been pushed to the limits to reproduce the reality of music with a dynamic range that is truly breathtaking.

High-Quality ES-LINK Analog Current Transmission
In addition to its XLR and RCA amplifier line connections, the N-01XD also features the ES-LINK Analog method of current transmission. Taking full advantage of the HCLD buffer circuit’s powerful current supply makes the N-01XD less susceptible to the detrimental effects of impedance on the signal route. It also enables a more powerful signal transmission, fully driving connected compatible devices.
Supports Super Audio CD playback by connecting ESOTERIC CD/SACD TRANSPORT
N-01XD supports the ES-LINK*, ESOTERIC’s unique ultra-wideband digital interface, that allows the N-01XD to playback Super Audio CD by connecting an ESOTERIC transport unit with a single-connection via a couple of HDMI cables or XLR cables.
* ES-LINK is ESOTERIC’s unique ultra-wideband digital interface. The N-01XD employs Version 5 which is the same version as the flagship Grandioso D1X, supporting wide-range transmission via a couple of HDMI cables (maximum: DSD 22.5 MHz, PCM 768 kHz/48-bit). Utilizing the double-track structure of HDMI, each signal of “Audio Data”, “LR Clock” and “Bit Clock” is transmitted in a fully balanced system. Unlike conventional digital transmission, it achives pure and ideal digital transmission by reducing processing load on the DAC significantly, instead of processing signal modulation on transmission side and demodulation on reception side.
The N-01XD now supports MQA decoding on all digital inputs, including MQA-CD signal read by a CD Transport unit.

Esoteric has partnerships with a wide range of streaming service and audio codec providers, and preparations are underway for compatibility with new services.*
*Regional restrictions may be implemented on some services.
Without complicated NAS settings for music server, the N-01XD can also be used as a simplified music server that integrates both player and library by connecting large-capacity storage devices to two USB ports on the front and rear of the unit.
No HDD/SSD can be accommodated inside the N-01XD.
The key to the sound quality of the N-01 and D-02X, which boasted a powerful and deeply carved three-dimensional sound, is found on the powerful power supply unit. The same story is applied on the N-01XD. An enhanced power supply section adds even more depth to the sound delivered from the N-01XD.
Each left and right D/A converter, digital circuit and the network module has exclusive power transformers, meaning a total of four independent toroidal-core power transformers are accommodated in the N-01XD, while the power regulator in the DAC section utlizes technologies and know-hows learnt from the development of the Grandioso P1X/D1X which employ a Low-feedback DC regulator configurated descretely, not relying ICs, minimizes amount of feedback. Consequently, the N-01XD achives a powerful sound with a sense of openness.
From our experience of the development on the Network Transport, the power supply dedicated to the network module employs linear elements refined for audio products instead of a stabilized switching power supply, while large capacity condensers, Schottky barrier diodes, and the EDLC (Electric Double-layer Capacitor) large-capacity supercapacitors with a total of 2,333,333μF capacity contribute significant improvement on sound quality
The clock circuit supplies a high-accuracy reference clock signal to the digital circuitry. The Grandioso Custom VCXO (voltage-controlled crystal oscillator) is a high-precision custom clock that utilizes a large crystal element to ensure exceptional sound quality with excellent center accuracy (±0.5ppm) and extremely low levels of phase noise.
In addition, the N-01XD also accepts high-precision 10MHz clock as precise as an atmic clock generated by ESOTERIC Master Clock Generators, the Grandioso G1 and the G-01. The external clock signal is applied to both network playback and USB Audio playback.
and Asynchronous Transmission
The N-01XD includes a USB audio interface for connecting to computers, and the driver and “ESOTERIC HR Audio Player” playback software can be downloaded free from the ESOTERIC website. The N-01XD supports asynchronous transmission and playback at high sampling rates up to 22.5MHz DSD and of 768kHz/32-bit PCM source files. Conventional digital audio inputs in XLR, RCA, and Optical formats are also supported for various sysytem configurations.
The N-01XD features the highly-acclaimed 2-layer thick aluminum and steel rigid chassis design. The chassis interior has a double-decker construction that both reduces interference between circuits and shortens the power supply paths to further improve sound quality. Each slot in every part of the chassis is precisely machined using laser technology to effectively reduce vibration. The entire bottom chassis is supported on 5mm-thick steel by our proprietary pinpoint feet (patent No;JP4075477,JP3778108) to create a complete mechanical grounding that protects against vibration.
The enclosure’s top panel utilizes a screwless semi-floating structure that further contributes to an open and expansive sound.
