ESOTERIC N-01XD

Network DAC N-01XD

The ultimate Network x DAC only ESOTERIC could achieve


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.


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 that strives for the original master sound.

FEATURES


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** supercapacitors 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 analog 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 digital input sources(*). In addition to conventional network input, MQA-CD playback is also possible when used in combination with a CD transport. *Only Grandioso P1X supports ES-LINK connection. (As of June 2020)


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), a 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 support 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). The 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 using the smartphone/ tablet to create a customized playlist for later playback. All screens have been intuitively designed for simple operation and access to playlists and libraries, making it easy for anyone to use. Yet it also offers an extensive range of refined features that meet the demands of even the most experienced users. Key to this achievement is a superb search and retrieval function that fully utilizes tag information. Images can also be stored using the app, enabling the user to instantly scroll through album artwork and libraries according to artist, year of recording, composer, or other categories. This use of tag information even allows tracks that have the same name but different formats to be easily identified onscreen. For more information about the ESOTERIC Sound Stream app, please see its product page here. For the ESOTERIC Sound Stream app manual, please see here.
