The World's Most Advanced, Greatest-Sounding Music Server: Aurender W20SE Supports Word and Master Clocks, Boasts Unsurpassed Output Options (Including Native DSD), Eliminates Noise

We'll come right out and say it: The Aurender W20SE is the most advanced, best-performing, and greatest music server on the planet. Designed for use with reference-grade DACs, able to playback up to 2x DSD in native form, and offering native DSD output as well as MQA decoding, W20SE offers discerning listeners external word clock and master clock support to bring literal mastering-studio-quality sound into your home.

Engineered to entirely eliminate noise from AC power supplies and AC mains, W20 utilizes LiFePO4 (LFP) batteries and linear power to power audio components. This engineering breakthrough is complemented by an All Digital Phase Locked Loop system with a newly upgraded OCXO clock to eradicate jitter from the equation. Need storage for your collection? A massive 4TB solid-state drive stores the most serious music collections while a 1TB solid-state drive gives you the benefits of cache playback.

W20SE literally has and does everything, extending to its 3.7-inch AMOLED screen. Overbuilt to the extremes with a fan-less switching mode power supply, isolated and damped drives, and an internal UPS to protect against power surges, W20SE comes with a full suite of connectivity to accommodate any conceivable setup or high-resolution listening option. Consider: A double-isolated LAN port, up to DSD128 output via SPDIF (DoP), up to DSD512 output on SPFIF (DSD to PCM), and up to DSD512 output on USB (native) abets up to 192kHz PCM upsampling on single wire and a head-turning 384kHz on dual wire. Dual AES output up to 24-bit/384kHz, up to 384kHz PCM output on SPDIF (dual wire), and up to 768kHz PCM output on USB also come standard.

Not to be outdone, Aurender's award-winning Conductor app makes song management and playback a cinch, and turns your iPad into the coolest full-function controller ever devised. In no way is W20SE for everyone. But for audiophiles with serious digital-audio systems and that want everything high-resolution offers, there's no finer option. 

Unparalleled Technology: LiFePO4 (LFP) Batteries Completely Eliminate Noise from the AC

Jitter and noise seriously affect DAC performance. W20SE completely eliminates noise from AC power supplies and AC mains through the use of LiFePO4 (LFP) batteries and linear power to power 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.

Mastering Studio Quality: External Word Clock Support and Dual-Wire AES/EBU Mode

Word Clocks are used in recording studios to synchronize timing between devices and ensure jitter-free and time-perfect data transmission. W20SE supports both word clock (dCS DACs or similar) and master clocks (MSB DACs or similar). In addition, W20SE features dual-wire AES/EBU mode, used by many reference digital-to-analog converters to separate transmission of left and right channels for ultimate fidelity.

Reference-Grade Oven-Controlled Crystal Oscillator (OCXO) Slays Jitter

OCXOs are among the most accurate and stable clocks in use and are significantly more accurate and stable than commonly used 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 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. 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.

4TB Solid-State Drive Storage with 1TB Solid-State Drive for Cache Playback
A solid-state drive provides 4TB of storage and a 1TB 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, minimizing 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.

Full Suite of Digital Audio Outputs and Ports, Internal UPS Protects from Power Surges
W20SE 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, W20SE comes with one Gigabyte Ethernet port and two USB 2.0 data ports. In addition, W20SE hosts the third bank of batteries that acts as an uninterruptible Power Supply (UPS). Should any sudden power outages occur, W20SE will shut down safely.

Built to the Extremes: Fan-Less Switching Mode Power Supply and Damped Drives
A fanless Switching Mode Power Supply delivers stable power to non-audio components and is enclosed in a separate compartment to prevent any interference to other components. W20SE's internal hard disk drives are suspended on floating brackets to minimize vibrations and housed in a machined aluminum compartment for complete isolation.

Experience the Award-Winning Conductor App
Aurender's award-winning Conductor App turns your iPad into a versatile user interface for W20SE. All settings and functions of W20SE can be easily accessed through the Settings menu, and Conductor comes with extensive features to make managing, viewing, and playing high-resolution music collections a breeze. Offering unparalleled support, sending a Remote Support Request using the Aurender Conductor App allows Aurender engineers to quickly diagnose and fix problems over the Internet.

Dedicated USB 2.0 Output with Ultra-Low-Noise Power Circuitry
W20SE's 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.

Databasing Made Easy: AMM and NAS Support
If you already have a NAS, W20SE is able to play music stored on NAS devices. The AMM (Aurender Media Manager) software is available for Mac or Windows. You can run AMM software on your platform of choice. Simply specify the location of your content on NAS then it will automatically find the Aurender in your local network and make a combining music database. Because it's transparent, once you run AMM, you can select the music with all the meta-data using the Conductor App without the knowledge of the location of your music files.
