Balanced DAC 2x ES9038Pro XMOS Bluetooth 5.0 MQA 32Bit 768kHz DSD512 BlackAn 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 DACAt 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 synthesizerThe 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 CPLDThe 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. FiltersSHARC DSPThe 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 InterfaceBehind 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 supplyThe 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 5.0New 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. ConnectivityThe 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. I2S Pinout
