*384kHz/24-bit PCM native playback in USB DAC mode and down-converted playback in network mode also provided.

ESOTERIC Sound Stream

Esoteric Sound Stream is an Apple iOS / Android application for tablets and smartphones designed with an emphasis on both sound quality and network playback operating ease. Its basic operation simply entails selecting musical tracks using the tablet / smartphone to create customized personal playlists and playing the selections or playlists. All screens for key operation, playlists, library, etc. are arranged for easy viewing, enabling even users unfamiliar with the app to operate it with intuitive ease. Its high degree of refinement even meets the rigorous demands of advanced and experienced users.
Key to this achievement is the app's excellent search and retrieval performance, which takes full advantage of tag information. Since images are also cached in the app, album artwork can be instantly scrolled through and libraries can be freely sorted into such classifications as artist, year of recording, composer or category. This use of tag information even allows musical numbers of the same name which differ in format to be easily identified on the screen.

Music Server Function

The N-05 can also be used as a simplified music server integrating both player and library by connecting a large-capacity storage device to the USB port on its rear panel. With the ability to be used as a secondary music server, even users new to the NAS directory structure can easily get started.

Streaming Services / Audio Codecs Support

Tidal, Qobuz, Spotify, and TuneIn

roon ready
Roon is the most engaging, enjoyable way to browse your music. Being Roon Ready means that the N-05 transparently discovers and connect to Roon, with no network configuration, with bit-perfect delivery of audio to your DAC. Together, Roon and the N-05 deliver the power, flexibility, and performance benefits of networked audio, with the easiest setup and highest reliability available.

MQA
MQA (Master Quality Authenticated) is an award-winning technology that delivers master quality audio in a file that's small enough to stream or download. Using pioneering scientific research into how people hear, MQA captures and authenticates the sound of the original studio performance.

Dual Mono D/A Converters

A feature of its Super Audio CD players, Esoteric's D/A converters and analog circuitry have won accolades for total sound quality. Employing Asahi Kasei Microdevices' AK4490 chip set, the converter is configured in four parallel and differential circuits (8 outputs) driving each channel to achieve superb sound quality with remarkable linearity and low distortion. Its discreet dual mono configuration also provides excellent channel separation.

34-Bit D/A Processing

The N-05 uses a 34-bit D/A processing algorithm to convert the high-resolution 34-bit PCM signal to analog. This 34-bit encoding resolution is an astounding 1,024 times more detailed than that of common 24-bit encoding. In the digital range, full advantage is also taken of this processor's high-bit data gradation to minimize calculation errors and provide faithful analog conversion for outstanding and highly sensitive powers of expression.

Esoteric-HCLD* Type 2 Buffer Amplifier

The N-05's Esoteric-HCLD Type 2 buffer amplifier boasts excellent direct current transmission capability, as well as a powerful drive output. Two of these buffer amplifier circuits are installed per channel and configured differentially to drive the XLR outputs, and in parallel to drive the RCA outputs. The strong drive provided to connected equipment ensures that the source's full dynamic range is recreated with a breathtaking sense of realism.

Robust Power Supply

A robust power supply is critical to the accurate reproduction of all the vibrant energy of music. The N-05 is equipped with a high-output power supply circuit that integrates an enormous, custom-designed toroidal transformer and an array of large capacitors to provide clean and steady power to each circuit block.

High-Precision VCXO Clock

A high-precision VCXO (voltage-controlled crystal oscillator) supplies a highly accurate reference clock signal to the digital circuitry. The N-05's large, custom-designed VCXO was jointly developed with Nihon Dempa Kogyo (NDK), a leading manufacturer of crystal oscillators, exclusively for high-quality audio playback. The cornerstone of quality sound, its large crystal element realizes both excellent center accuracy (±0.5ppm, as shipped from the factory) and extremely low levels of phase noise to ensure exceptional sound playback quality.

External Clock Sync Function

Connecting the N-05 to an external G-02X or G-01X Master Clock Generator allows more accurate synchronization between internal digital circuits, thereby enabling significant improvements in system sound quality. The N-05 is compatible with 44.1/88.2/176.4kHz word clocks as well as both 10MHz and 22MHz direct master clock LINK.*
*The clock generator's master clock signal is used ‘as is’ by the D/A converter, bypassing its internal PLL circuit to allow straighter, more high-accuracy D/A conversion.

Versatile D/D Converter

The N-05 is equipped with a highly versatile D/D converter and digital filter. In addition to playback at the original sampling frequency, 2x, 4x and 8x up-conversion of the PCM digital signal, as well as cross-format conversion of PCM and DSD using a proprietary algorithm, are all freely selectable. Digital filtering (of both PCM and DSD) can also be enabled or disabled as desired.

A Multitude of Digital Inputs

The N-05's array of digital inputs include USB (x1), coaxial (x2) & optical (x1). The coaxial and optical inputs are compatible with both 192kHz/24-bit PCM and 2.8MHz DSD (DoP), while the USB port supports asynchronous transmission and native playback of 2.8/5.6/11.2MHz DSD and 384kHz/32-bit PCM.

Complete Noise Isolation

The analog circuit following the N-05's D/A converter is separated from its digital circuitry by an isolator that ensures complete noise reduction to maintain the purity of the analog sound output.
