It also has a dual balanced preamplifier derived directly from the Grandioso models along with a high-quality built-in headphone amplifier.

The “XE” model retains its acclaimed functionality while meticulously refining every circuit component through a newly optimised design.

Enjoy the refined Esoteric signature sound to your heart’s content.

Master Sound Discrete DAC G2

The Esoteric Master Sound Discrete DAC G2 is a fully in-house designed, FPGA-based, multi-level  (delta-sigma) D/A converter built with meticulously selected discrete components.

This unique architecture’s ultimate goal is to effortlessly reproduce music’s true dynamics and power, surpassing the limitations of conventional DAC IC chips.

Its large-scale circuit design comprises 16 elements per channel, with all key components configured in complete independence.

In the XE model, the new G2 DAC features a completely redesigned resistor network—the first stage of the analogue domain, achieving even purer signal processing.

This breathtakingly powerful, dynamic, and musical architecture delivers an un-compromised, pure listening experience.

New Low-Noise Register Network

In a DAC, the resistor network is a critical circuit that converts the digital signal generated by the FPGA into an analogue signal through precision resistor elements.

For the new G2 version of the DAC, Esoteric applied development achievements from their flagship network streamer, the Grandioso N1.

This approach simplified and optimised the circuit responsible for switching the resistor elements on and off.

In addition, capacitors placed in close proximity to the resistor network improve current supply stability, enabling the generation of purer analogue signals with significantly reduced noise.

Advanced Digital Processing Capabilities

The G2 DAC supports the latest formats, including native DSD 22.5 MHz playback. Independent FPGA-based digital processing algorithms, optimised separately for DSD and PCM formats, enable D/A conversion that maximises the advantages of each format.

High-Precision MELF Resistors

Critical resistor elements within the DAC circuit employ high-precision MELF resistors to enhance computational accuracy.

Additionally, the circuit’s carefully selected discrete components contribute to sound reproduction characterised by vivid live presence, superb dynamics, and an organic, natural texture.

Master Sound Discrete Clock for digital player

The clock circuit, which is critical for high-quality digital playback, now features Esoteric’s proprietary “Master Sound Discrete Clock for Digital Player.”

With its unique circuit design and carefully selected discrete components, the clock circuit achieves high sound quality, reflecting Esoteric’s philosophy down to the finest detail— an approach that cannot be realised with generic clock modules.

The 4th Generation “Esoteric Network Engine G4”

The Esoteric N-05XE features the fourth-generation “Esoteric Network Engine G4,” which incorporates an SFP port for optical network connectivity.

Equipped with large-capacity RAM and a powerful CPU, it delivers advanced processing performance.

The network power supply section employs a large linear power supply that is completely separated from the audio power supply.

Each network component is powered directly via its own independent power line, separated from the transformer windings.

By eliminating noise-generating switching elements, the N-05XE achieves a smooth, vinyl-like sound with rich detail and natural musical flow.

SFP Port

The Esoteric Network Engine G4 is equipped with a built-in network switch function and has two network interfaces: an Ethernet RJ45 connector and an SFP port.

By connecting the N-05XE to an external network switch using an SFP module and fibre-optic cable, the signal can be isolated from network-borne noise, resulting in unparalleled playback purity.

For maximum flexibility, both the RJ45 and SFP ports can be used simultaneously, tailoring the setup to your preferences and requirements.

Music Server Function

The N-05XE is equipped with USB ports (USB-A ×1, USB-C ×1) and can function as a music server / NAS by connecting up to two USB storage devices, such as flash drives or HDD/SSD units.

Esoteric Sound Stream – Intuitive Control Meets Audio Quality

The Esoteric Sound Stream app, available for both Apple iOS and Android devices, is designed to combine exceptional sound quality with effortless usability.

Tailored for smartphones and tablets, this innovative app allows users to easily browse, manage, and customise their music playback experience with just a few taps.

With its intuitive interface, creating and managing playlists becomes seamless.

All screens are thoughtfully designed for straightforward navigation, ensuring that music libraries and playlists are easily accessible to users of any experience level.

At the same time, the app offers a suite of advanced features to satisfy even the most seasoned audiophiles.

The Dual-Mono, Dual Balanced Preamplifier at the Heart of the System

The preamplifier forms the core of the system and defines the essence of its sound.

The Grandioso’s high fidelity and musical expression embody Esoteric’s philosophy and technology.

These qualities have been passed down to the N-05XE, which inherits its lineage.

The acclaimed dual mono, dual balanced configuration delivers dynamic yet delicate sound, capturing the performer’s sensibility.

A Total of 8 Circuits for L/R, Hot/Cold

The N-05XE uses an attenuator circuit with a high-fidelity, dual-mono, dual-balanced configuration.

This configuration comprises eight independent circuits that separately handle left and right channels, as well as positive and negative signal paths.

This configuration achieves clear sound quality with excellent channel separation and phase accuracy.

In the XE model, the attenuator’s power supply section is completely independent from the other power circuits, which further refines the purity of reproduction.

High-Precision Ball Bearing Volume Control Knob

Providing ultra-smooth analogue operating feel, the N-05XE’s volume control utilises the same Ball-Bearing support mechanism used in Esoteric’s flagship Grandioso line.

The volume knob itself is precision-machined from solid aluminium, ensuring exceptional tactile quality and mechanical precision.

Dual-Mono Parallel Single-Ended Headphone Amplifier

Experience high-end headphone listening in your own space.

The N-05XE features a newly developed dual-mono, parallel single-ended headphone amplifier.

Esoteric’s accumulated expertise in analog amplifier design is brought together in this circuit, delivering exceptional sound quality for serious headphone listening.

Evolved for an Even More Open Sound

The circuit is engineered to eliminate differences in sound quality between speaker and headphone playback.

This is achieved by employing the HCLD line-stage preamplifier renowned for its high current output, as the headphone amplifier itself.

The dual-mono architecture incorporates independent left and right power supply circuits.

During headphone operation, the two amplifier circuits switch to parallel single-ended operation, resulting in sound with even greater openness than previous models.

The amplifier is equipped with two output formats: a 4-Pin XLR and a ¼ (6.3mm) stereo phone headphone output.

With a high output power of 1,200 mW per channel (32 Ω load), it drives high-end headphones with ample authority, control, and musical vitality, delivering uncompromising performance and heightened musical expressiveness.

Built-in Bluetooth® Receiver

The N-05XE features a built-in Bluetooth® receiver supporting high-quality audio codecs, including LDAC, LHDC, Qualcomm® aptX™ HD audio, Qualcomm® aptX™ audio, AAC and SBC.

This enables high-fidelity wireless playback from smartphones and other compatible devices.

The Esoteric N-05XE also supports multipoint connectivity, allowing simultaneous connection to multiple devices for seamless switching.
