Innovative Technology with battery power/dual wire/master clock input
In digital audio, jitter and noise in the audio signal can seriously affect the performance of digital-to-analog converters. The Aurender W20 is the world's first music player to completely eliminate noise from AC power supplies and AC mains through the use of LiFePO4 (LFP) batteries to power audio components. An FPGA-based All Digital Phase Locked Loop system with an Oven-Controlled Crystal Oscillator (OCXO) clock is used to maintain long term jitter to below negligible levels, and specially designed circuitry provides clean, noise-free power to the dedicated USB digital audio output. A solid-state drive cache for playback and extensive shielding using thick aluminum partitions also minimize and eliminate the many types of jitter and noise associated with the use of disk drives for playback.
Full Range of Digital Audio Outputs and Ports for Network Connectivity
Designed to be matched with high performance digital-to-analog converters, the Aurender W20 is equipped with various SPDIF outputs (BNC, AES/EBU, coaxial, optical) and one dedicated USB Audio Class 2.0 output. For network connectivity and file transfers, the W20 comes with one a Gigabyte Ethernet port and two USB 2.0 data ports. 
Separate LiFePO4 (LFP) Battery Power Supply for Audio Components
Two banks of LiFePO4 batteries alternately power audio components and recharge. This completely isolates audio components from ground noise and also eliminates jitter incurred in converting AC to DC.
Internal UPS to protect the storage from the unexpected power outage
A third bank of batteries acts as an Un-interruptible Power Supply (UPS) and should any sudden power outages occur, the Aurender W20 will shut down safely.
Oven-Controlled Crystal Oscillator (OCXO) for long term jitter reduction
OCXOs are among the most accurate and stable clocks in use today. OCXOs are orders of magnitude more accurate and stable than commonly used ordinary crystal oscillators usually found in computers. Temperature changes cause crystal oscillations to fluctuate, which can lead to jitter in the digital audio signal. Moreover, ordinary crystals are much less stable and lose accuracy over time. In OCXO clocks, a very stable high grade crystal oscillator is enclosed in a compartment and kept at a constant temperature to prevent jitter from temperature fluctuations.
FPGA-based All Digital Phase-Locked Loop System
An All Digital Phase-Locked Loop system (ADPLL) incorporating Field-Programmable Gate Arrays (FPGA) with OCXO clocks precisely times digital audio data transmissions and minimizes jitter to below negligible levels
12TB Hard Disk Drive Storage with Solid-State Drive Cache for Playback
An internal hard drive provides 12TB of storage and a 240G solid-state drive is used to cache music for playback. If a selected song or album is already cached to the solid-state drive, the hard drive will remain asleep. This minimizes wear and tear on the hard drive. By caching songs to the solid-state drive for playback, electrical and acoustic noise resulting from spinning disks, moving heads and motors are also completely eliminated.
Dedicated USB Audio Class 2.0 Output with Ultra Low Noise Power Circuitry
The dedicated USB Audio Class 2.0 output is designed to deliver an exceptionally transparent audio signal free of noise, and is shielded from outside electronic interference. When not in use, the power to the USB Audio output can be shut off depending on the USB DAC’s requirement.
Isolated and Damped Hard Disk Drives with its own Aluminum casing
The internal hard disk drives are suspended on floating brackets to minimize vibrations and housed in a machined aluminum compartment for complete isolation.
