Extreme performance of hardware configuration

UDS Series Stream Servers have unprecedented powerful performance, and also have the top high performance of hardware configuration (ARM + FPGA + DSP + ES9018 * 2 decoder + WM8741 * 2decoder,ES9018 and WM8741 D/A converter for each channel,Dual Differential coupling for optimal performance), using three groups independent clock oscillator (44.1KHz, 48KHz, and DSD) format which is developed specifically for digital audio to ensure that the clock performance makes low clock jitter and phase noise - Phase Jitter ± 1kHz -150 dBc/Hz (Typ).

The ultimate audio format

Support more digital audio formats, including DSD/DTS/PCM (FLAC, DSD/ISO/DIFF/DSF, APE, AIFF, Apple Lossless(ALAC), AAC, etc), 
and support PCM 32Bit/768KHz, DSD 2.8M-5.6M superhigh stream audio formats. All of the signal adopt source output to process hardware decoding, offering outstanding dynamic performance.  

Modular DIY accessories

All functions employ modular structure. Every module can be DIY selected according to users’ demand(including the ES9018 * 2 DAC module, WM8741 * 2 DAC module, HDMI DAC module), which is very flexible to combine more personalized Stream Servers.

The ultimate user experience

Supporting WIFI Direct control DLNA and Airplay (without Router) and support for multiple platforms Remote APP - Android/IOS/Windows PC/Mac. The network control protocol through optimization can be compatible with more audio formats Remote control, such as DSD/difi, dsf formats etc.

Personalized Internet radio

Easy to use Internet radio. It supports internet radio station logo display, radio recording, allowing users to manually add radio stations in the background and creating personalized playlists as well as other handy applications;  

All of the audio parameter settings
Support all of the audio parameters settings, including ES9018,WM8741 PCM and DSD formats digital filter modes, phase, output level, S / P DIF input and output ,Analogue recording format,etc the complete DAC parameters
