Introduction
 
U200 is a high price/performance ratio USB DAC and headphone amplifier which is designed for dedicated high performance audio. 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; Oxygen Free Copper (OFC) lead outs 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. 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.

 

 
WiFi Support: 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.
