Master Sound Discrete DAC G2

The Esoteric Master Sound Discrete DAC G2 is a fully in-house designed, FPGA-based, multi-level ΔΣ (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 analog domain, achieving even purer signal processing. This breathtakingly powerful, dynamic, and musical architecture delivers an uncompromised, 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 analog signal through precision resistor elements.

For the new G2 version of the DAC, Esoteric applied development achievements from our flagship network streamer, the Grandioso N1. This approach simplified and optimized the circuit responsible for switching the resistor elements on and off. In addition, capacitors placed in proximity to the resistor network improve current supply stability, enabling the generation of purer analog 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, optimized separately for DSD and PCM formats, enable D/A conversion that maximizes 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 characterized by vivid live presence, superb dynamics, and an organic, natural texture.

Mater Sound Discrete Clock for Digital Player
