YULONG Audio is a China based brand, they design and manufacture high-end audio products with special focused on All-in-One products that combine high quality DAC, Preamp, and Headphone Amplifier in a compact box. Their products lineup like Yulong Canary II and DA10 DAC combine leading-edge technologies, rigorous engineering principles, exquisite craftsmanship, and the passion of audiophiles aiming to deliver sound good, measure well and function reliably.

 

 

They unveiled their newest flagship all-in-One for personal and home Audio applications product, YULONG DA1, with a price tag US$2,499. It has a simple and convenient control system, which can switch the function circuit modules separately. It can work as a pure DAC, pure preamplifier, pure headphone amplifier independently or a holistic machine with best overall performance. DA1 adopts AKM flagship 32-bit AK4499EQ DAC chipset and well-received proprietary Jitter Interface Control (JIC) FPGA solution for top-notch digital processing performance.

At pure DAC mode, the power supply to the headphone amplification and preamplifier circuit will switch into parallel regulator automatically, this will maintain the circuit in optimal temperature and audio performance. With top-rated decoding capability, dual clock (SYNC/ASYNC) multiple filtering modes switch to combine different sounds. DA1 has a widely recognized XMOS solution with customized (with license) Thesycon driver. The USB supports PCM up to 32Bit/768kHz, DSD up to native DSD512, and AES, Coaxial, Optical inputs support DoP 128 and 384kHz. It is lways one step ahead to provide better experience you want. 

 

 

The analog section is a fully balanced design with discrete components. The Class A circuit can be configured as a headphone amplifier or pre-amplifier depending on the user application. The headphone amplifier offers an exceptional driving capability and can handle headphones with different impedance, sensitivity, and design. 99 steps digitally controlled analog volume provide linear and accurate adjustment for different headphones parings. Rated at up to 5 watts per channel (at 32 Ohm), you can expect a stellar dynamic range and headroom, even when fed with a difficult load.

With both digital and analog inputs in place, YULONG DA1 can serve as your personal audio hub for varieties of applications. Exceptionally well measurement and stunningly refined and musical sound makes it worthy. The DA1 operation is controlled intuitively through a single high precision probably damped volume knob. All playback and setting information are clearly displayed on the IPS wide-angle LCD screen. USB Audio supports MS Windows, macOS, and Linux to meet different users' need. It also optimizes the compatibility and stability with Android, iOS mobile devices and tablet devices.



To fully explore DA1 function, Yulong have designed an exotic 240W external power supply to enhance the audio performance for the most demanding users. You could stack up with the optional power supply that they developed alongside the DA1 from the very beginning. This is an optional but significant upgrade from the 50W power supply in the Yulong DA1.
