DAC Headphone Amplifier AK4497 32bit 768kHz DSD512
The DA10 is Yulong's latest high-end integrated system, integrating DAC, preamplifier and headphone amplifier. This new creation is based on 15 years of experience and research and development in the design of high-fidelity audio products.
For this DA10, the brand does not do half measures and integrates a set of high-end components to develop excellent audio performance: DAC AKM AK4497 chip, FPGA, FIFO digital buffer, PLL clock with femto crystal.
At the heart of the DA10 is the digital signal processing stage, based on an FPGA chip that allows the digital audio signal to be recovered and corrected, the data to be stored in the FIFO buffer and synchronized with the PLL circuit and the femtosecond clock generator. These different steps allow to have a clean signal and without jitter. This is then transmitted to the AKM AK4497 digital-to-analog conversion chip. The latter supports high sampling rates, up to 32bit 768kHz for PCM and up to DSD512.
The LPF stage incorporates ultra-low distortion AOPs OPA1611 and OPA1612, followed by a low distortion AOP1622 also in buffer. The output level is controlled by a PGA2311 when the device is used as a preamplifier and headphone amplifier. A 50VA Plitron toroidal transformer and a series of 23 low noise regulators provide a clean power supply for the entire circuit.
DAC Headphone Amplifier AK4497 32bit 768kHz DSD512The DA10's headphone amplifier does not deviate from this rule and benefits from the same design quality as the rest of the device. Featuring a dedicated power supply circuit, this Class A amplifier features a discrete design, a JFET input, a stable and adjusted polarized current and a high output current thanks to the MJD243/253. Operating conditions have been optimized by analyzing temperatures using thermal imaging to allow the circuit to develop its full capacity without degrading it.
For its connectivity, the DA10 offers a complete panel for easy connection to most devices. On the input side, there is a USB-B connector, AES/EBU, Toslink Optics and Coaxial S/PDIF. The USB input is combined with a high quality XMOS U208 interface, allowing you to enjoy high resolution files and get the most out of the AK4497 DAC chip. For outputs, the rear panel offers unbalanced stereo RCA and balanced XLR. The front panel has two balanced headphone outputs with 6.35mm jack and 4-pin XLR.
The DA10 offers several filters to adapt the sound reproduction to your listening style, your audio system and the different types of music. The first one is simply a balanced filter. The second is more suitable for classical music. The third and last one highlights a beautiful vocal presence, ideal for example for jazz.
