YULONG DA10 is our latest reference grade All-in-One DAC/Amp/Pre for Personal Audio application. It is designed around AKM’s Premium 32-bit AK4497EQ DAC chipset and incorporated our YULONG JIC (Jitter and Interface Control) System, a digital audio technology that will perform digital audio receiving, low noise clock synchronization, FIFO buffering and Dual PLL in our proprietary FPGA solution.
The analogue section is fully balanced design with Class A headphone amplification offers exceptional driving capability and natural sounding. The DA10 measures exceptional well, and it also sounds stunningly refine and musical because we have devoted a lot of resource to fine tune the audio performance through repeated audition and modifications.
The key features of DA10 are:
● Proprietary high precision low tolerance YULONG JIC (Jitter and Interface Control) System:
o Optimize data integrity and enhance digital signal quality.
o De-jitter and minimize digital artifact.
● Outstanding digital audio capability:
o Design around AK497EQ DAC chipset with industry-leading 32Bit/768kHz and DSD512.
o Widely recognized XMOS XU208 solution with customized (with license) Thesycon driver to enhance sound quality and stability.
o All inputs interface support DoP64 and DoP128, USB input interface supports Native DSD64/128/256/512 additionally.
o Choices of 3 digi talfilters and three SSM (Sound Signature Modes) to fine tune your system for different music genres and personal preference.
o Custom developed 1.7nV low noise regulator at reference voltage and analogue supply for DAC circuit.
● State-of-the-artanalogue implementation:
o 99 steps Microprocessor controlled analogue volume for Preamp and headphone output to maintain stellar dynamic range.
o Fully discrete, JFET input, constant current biased, DC coupled Class A headphone amplification for outstanding driving and handling capability.
● All-in-one design with comprehensive connectivity:
o Fully balanced design, low impedance DAC line output, high current preamp and headphone amplification.
o USB Audio supports MS Windows, macOS, Linux, Android and iOS.
● Multi-stage low noise power supply to digital and analogue system independently from a high efficient low interference Plitron 50VA toroidal transformer
and dozens of low noise regulators.
● Elegant and sturdy aluminum chassis with large IPS wide angle display, supported by unique suspension feet.
