U200 Wi-Fi DSD 32bit 384KHz USB Digital to Analogue Decoder (DAC)
  • Work as a network player when the optional WiFi module is installed. In this configuration, it can:
    • Play the music files stored in your phone/tablet, and turn it into a high resolution digital player.
    • Play the music resources stored in Network Attached Storage (NAS) or network media server.
    • Supports PCM formats up to 32Bit/384KHz and DSD in network player mode.
  • USB input supports PCM formats up to 32Bit/384KHz and DSD.
  • Ultra-low phase noise clock.
  • Flagship DAC chip AKM4495 which was designed with sound impression in mind.
  • Class-A headphone amplifier.
  • Integrated AC power supply which ensures effortless, full-sized energy in a small footprint.
  • USB as the only digital input interface which omitted unnecessary digital inputs, ensures high Cost/Price ratio.
  • Analogue input enables U200 as a headphone amplifier.
U200 is a high C/P ratio USB DAC and headphone amplifier which is designed for mobile device and computer users. It supports PCM formats up to 32Bit/384KHz and DSD.
By integrating a strong AC power supply under its tiny enclosure, U200 provides driving power same as the full sized equipment while maintains portability.
When working together with the optional WiFi module, the U200 is turned to a network player with easy operation and exceptional audio quality.
In close cooperation and development with Saviaudio, U200 utilizes their high quality SA9227 for its USB audio interface solution. Together with Sophisticated circuit design and customized ultra-low phase noise clock, excellent results are now available through USB transmission.
AKM 4495, the flagship DAC chip of the Premium Audio series from AKM is playing in the core of decoding. It may not have the best measurement performance, however its design pays attention to the Hi-Fi philosophy, such as Oxygen Free Copper (OFC) lead outs and internal hook ups and filters optimized for actual listening experience rather than measurement. Such details distinguish this chip from other solutions, which are mostly optimized for measurement performance, and make it a DAC chip with music sense in its nature.
The power supply in U200 is AC internal regulation which is a step up from the external DC supply on its predecessor U100, and provides an optimized distribution for the DAC and the headphone amplifier, and results in a full output scale comparable to full sized system.
The headphone amplifier is fully discrete, class-A construction and paired with a dedicated analogue input, so the U200 can be used as a pure headphone amplifier if desired.
As all products created by YuLong, our acoustic team has spent enough time to fine tune the sound, by long term audition with substantial amount of popular audio equipment, with AKM4495’s musical nature in mind. U200 is an all-around, rich and full, very musical DAC with exceptional driving power in its class, and it can drive most popular dynamic headphones with satisfied result.
It packs full-sized capability under a small footprint, it is highly mobility while flexible for different applications, providing excellent user experience.
WiFi playback: Smart phones and tablets based on iOS or Android platform can install the free APP, and then it can play music stored either on the phone/tablet, or NAS and media server. All these applications support up to 32Bit/384KHz and DSD format.
USB DAC application
Driver is required for Windows operating system. Please download the driver from
Please disable AntiVirus software during the installation when needed.
After installing the driver, connect the U200 to your computer with USB interface, hook up the power cable and switch the power on, then choose U200 as the output device in your music play back software, and you can now enjoy the brand new music experience brought by the U200.
To ensure the U200 is properly recognized by computer, please connect it with USB before the power is turned on.
For better result please use ASIO, Kernel Streaming or WASAPI outputs. Please refer to your playback software for these settings.
Please set your playback software to SACD or DSD mode when playing these formats. The DSD indication light on the U200 will be turned on when decoding DSD signal.
