  • Support MQA FULL decoding. Different equipment and different playback methods will play different sound effects of the same MQA file. The way MQA works is to "fold" the analog audio like origami, become a smaller file. Once this file is played on a decoder that can read MQA files, can reopen the folded part to release the highest resolution music. Admittedly, The playback quality will depend on your device, but at least this file has the potential to reproduce the original recording.
  • Using CPLD programmable logic chip, self-developed logic function digital integrated circuit, built-in clock management, 2nd PLL digital shaping, DOP demodulation, PCM/DSD depop switch and other exclusive technologies, laying a solid foundation for excellent sound quality;
     
  • 8-channel hybrid discrete IV conversion circuit and independent adder circuit, fully meet the requirements of ES9038PRO output current, and ensure high sound quality from the source;
  • Two Audio Grade Toroidal transformer for Analog / Digital independently.  
  • Native fully balanced architecture, without any conversion, complete two-channel fully balanced output;
  • The analog LPF circuit uses the discrete line independently developed by Gustard, and has carefully adjusted each level of parameters to achieve the best working condition;
  • Bluetooth 5.0 supports LDAC, AAC, SBC, APTX
  • Using LCD screen and newly developed user interface, give you a new experience, full-function remote control. No matter where you sit (near the device), can control it at will.
  • X26PRO will have USB, Optical, Coaxial, and IIS inputs. For outputs, it'll have RCA and XLR capability. Support LVDS level differential I²S reception (using HDMI interface), it can accept the lowest jitter digital audio! Support up to 8 input modes, compatible with most audio sources! This dac decide mqa through only usb. 

GUSTARD X26PRO

Balanced DAC 2x ES9038Pro XMOS Bluetooth 5.0 MQA 32Bit 768kHz DSD512 Black

Gustard X26Pro DAC Symétrique 2x ES9038Pro XMOS Bluetooth 5.0 MQA 32Bit 768kHz DSD512 Noir

An enhanced version of the Gustard DAC-X26, the X26Pro offers a series of improvements designed to make it both more powerful and more versatile. These now include a Bluetooth 5.0 receiver, improved clocking, MQA file decoding and improved heat dissipation.

The X26Pro's no-compromise design incorporates high-end audio components to deliver rich, accurate, dynamic audio as close to the original signal as possible.

ES9038Pro Dual DAC 

At the heart of the X26Pro are two DAC ESS ES9038Pro DAC chips for digital-to-analog conversion. Each channel therefore has its own conversion chip and power supply to deliver the best possible audio performance. In addition, these chips support high sample rates, which in the case of the Gustard X26Pro can go up to 32bit 768kHz PCM and DSD512 on the USB and I2S inputs.

These chips are accompanied by a Class A LPF integrating only discrete components, specifically optimized for the ES9038Pro DACs.

Ultra low noise clock synthesizer

The X26Pro incorporates a K2 clock synthesizer, which provides a second clock signal and synchronizes decoding. This allows DAC performance to be independent of the source equipment.

Altera MAX II CPLD

The logic functions of the X26Pro are entrusted to a CPLD, including a clock management system, second PLL digital processing, DoP decoding and many other functions that contribute greatly to the performance of the device.

Filters & SHARC DSP

The Gustard X26Pro offers several digital filters, PCM and DSD, to adapt the sound reproduction to your listening and audio system, while reducing residual noise.

In order to offer high quality filters, Gustard has chosen to develop its own filters using a DSP Analog Device SHARC chip. This solution integrates an anti-aliasing algorithm designed by Gustard, using a high-precision 64bit floating point system. Moreover, this algorithm has been optimized to work perfectly with ESS DACs and ensure the best possible sound quality.

XMOS USB Interface

Behind the USB-B input of the X26Pro is a high-performance XMOS XU216 USB interface. This interface enables fast and efficient data processing, while supporting high-resolution data streams.

Power supply

The power supply for the X26Pro uses two toroidal transformers and a discrete 8-channel hybrid I/V conversion circuit. This provides the entire system with a consistent and extremely clean and stable power supply, which is essential for high-quality sound reproduction.

In addition, each channel of the X26Pro's analog circuitry uses an independent power rail to limit interference and noise.

Bluetooth 5.0

New in this Pro version of the Gustard DAC-X26 is the integration of a Qualcomm CSR8675 Bluetooth 5.0 receiver chip. This chip allows you to broadcast your music remotely and in high quality, thanks to the support of protocols such as aptX HD and LDAC.

Connectivity

The Gustard X26Pro benefits from a complete set of connectors capable of adapting to many audio systems. Inputs include USB-B, I2S LVDS over HDMI, Coaxial, AES, Optical and Bluetooth reception. On the output side, the X26Pro offers balanced XLR and unbalanced stereo RCA. Note that the analog circuitry of the device uses a balanced architecture without conversion with a total separation of the two outputs.
