The manufacturer is using the ESS USB solution, which is a new solution just listed, so the Daphile or Volumio system is not particularly good for its identification and compatibility. So if you want to buy X26 to connect these systems, please consult before buying, thank you!

The X26 features a high-performance digital filter and GPLL-M1 high-precision phase-locked loop module self-developed by Gustard. This makes the X26 reach a new level of sound quality in all of Gustard's DAC product lines.
As we all know, digital filters are an inseparable part of modern high-performance audio DAC system design. The most critical design goal of digital filters is to reduce the aliasing noise in the audio band of the digital domain. This process mainly performs oversampling and noise shaping on the original digital audio signal to achieve better sound quality.
Modern audio DAC chips generally integrate digital filter functions, and their audio objective performance has reached a good level. However, the DAC on-chip digital filter is limited by various aspects such as cost and computing power, and its sound quality performance can no longer meet our pursuit of higher sound quality.
So we developed our own high-performance digital filter solution on the Analog Device SHARC digital audio DSP platform. The solution is equipped with a high-performance anti-aliasing noise algorithm developed by Gustard, which uses high-precision floating-point 64-bit arithmetic in some key digital signal processing. This algorithm has been optimized for ESS Technology DACs to ensure high sound quality.
The GPLL-M1 high-precision phase-locked loop module has ultra-low residual phase noise, and the recovered audio clock implements an ultra-low jitter at the femtosecond level. Thanks to the complex algorithm, the jitter suppression performance is excellent, and the additional jitter introduced by various factors can be easily solved.
The master clock of the ES9038 chips is also supplied by the GPLL high-precision phase-locked loop module. It works directly in synchronous mode to bypass internal ASRC resampling and no longer relies on ASRC to guarantee performance (no need for 100M clock).
 
 

Gustard DAC-X26 technical features:
The X26 uses two ESS Technology's flagship audio DAC chip ES9038PRO for dual mono audio digital-to-analog conversion. Each channel uses a separate ES9038Pro chip, and each channel is completely independent power supply and grounding for best performance.

The X26 uses the GPLL-M1 high-precision phase-locked loop module with ultra-low residual phase noise, and the recovered audio clock can reach the femtosecond level of ultra-low jitter. Thanks to the complex algorithm, the jitter suppression performance is excellent, and the additional jitter introduced by various factors can be easily solved;

The X26's audio digital signal processing is implemented with the Analog Device SHARC digital audio DSP, equipped with Gustard's proprietary high-performance anti-aliasing noise algorithm, which uses a high-precision floating-point 64-bit algorithm for some key digital signal processing. This algorithm has been optimized for ESS Technology DACs to ensure high sound quality;

The X26 uses the CPLD programmable logic chip, which is equipped with Gustard's self-developed multi-year custom digital logic functions, including clock management, 2nd PLL digital shaping, DOP decoding, PCM/DSD depop switch and other exclusive technologies, which lays a solid foundation for excellent sound quality. ;

The X26 uses two high-quality audio dedicated toroidal transformers to power the digital and analog circuits, thus achieving complete independent power supply without mutual interference;

The X26's analog circuitry uses a native fully balanced architecture with no single-ended/differential conversion for complete balanced and single-ended output;

The X26's analog LPF circuit uses a self-developed discrete circuit, and the parameters of each stage of the circuit have been carefully adjusted to achieve the best operating point;

X26 supports 0dB~-90dB, a total of 90 gears of digital volume, with the included high-quality remote control to easily adjust the volume;

All digital inputs of the X26 support DSD:

IIS: DSD64, DSD128, DSD256, DSD512;

SPDIF, AES/EBU: DSD64, DSD128 (DOP mode)

Optical: DSD64 (DOP mode);

USB: DSD64, DSD128, DSD256, DSD512 (DSD native Only);

 
The X26 is equipped with three digital filter algorithms developed by Gustard and can also be turned on.
PCM: VIVID (recommended) / COMPOSITE / GENTLE;
DSD: 47K/50K/60K/70K;

NOS mode: (only sampling rate of 176.4KHz and above can be used), NOS (No OverSampling) does not perform digital oversampling, directly digital-to-analog conversion of the original digital audio signal. This mode is recommended for use with audio player software such as HQplayer with its own oversampling digital filter function;


X26's USB digital audio interface module uses ESS Technology's USB AUDIO solution, up to PCM768K DSD512;

The X26's screen brightness is adjustable and it is automatically remembered after 10 seconds of no operation. After power-on, it will automatically maintain the settings before the last power-off, and humanized operation control;

The X26 features a brushed aluminum chassis with optional colors including silver (matte white) and black;

X26 chassis size: width 330* depth 260* height 65MM (excluding protruding parts);
X26 package size: length 420 * width 360 * height 175MM;
X26 package weight: 7KG;
The X26's AC supply voltage mode can be manually switched between 110/115V and 220/230V;
X26 XLR interface definition: US standard (1 ground, 2 hot, 3 cold)

The X26 uses a newly designed 8-channel hybrid discrete I/V conversion circuit and an independent adder circuit to fully meet the ES9038Pro's large output current requirements for I/V conversion circuits, ensuring high performance from the source;



Each channel of the X26 analog circuit is equipped with an independent power supply to ensure sufficient energy and no interference with each other;

 

 


Each channel of the X26 analog circuit is equipped with an independent power supply to ensure sufficient energy and no interference with each other;
 



The X26's analog LPF circuit is a fully discrete Class A circuit specifically tuned for the ES9038Pro chips.

Because each discrete device only needs to be considered separately to perform its own performance, there are fewer application limitations for a single discrete device, so that the performance of each discrete device can be fully utilized.

Because the active devices in the integrated circuit are integrated into the chip, they cannot be individually adjusted in a targeted manner. Tuning a circuit that uses discrete components is more flexible than using an integrated circuit, and the parameters of each stage can be freely adjusted to achieve an optimum operating point. In addition, circuits using discrete devices are more developable and relatively controllable for distortion characteristics, which can result in a more variability sound style for different audio DAC system architecture designs.

The disadvantage of discrete devices is that their parasitic parameters are highly influential, and designing and tuning is more difficult than using integrated circuits. This requires a certain technical experience and a long adjustment process. The consistency of the circuit using discrete devices is also relatively weak, so the selection of components used is very demanding.



The power circuit of X26 adopts the design of two sets of multi-stage voltage regulator and filter circuit for each channel to ensure mutual interference.
