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 ul-tra-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 ana-logue input, so the U200 can be used as a pure headphone amplifier if desired.

Recommendations for better user experience

U200 performs better when warmed up. We suggest giving it at least 15 minutes before lis-tening. Due to the class-A amplification it is normal to feel warm on its housing. Please en-sure good air ventilation around the working U200 to avoid overheating.
To ensure the best possible audio quality, please use high quality USB cable such as YuLong CU2. Avoid USB hub or extension such as USB ports in the front of a desktop or in a monitor.
AC mains power shall be well grounded. Poor grounding will cause safety hazard, and causing noise and ground loop between U200, computer and peripherals.
