The Most Advanced, Greatest-Sounding Music Server in the World: Unsurpassed Aurender W20 Supports Word Clocks and Master Clocks, Includes Tons of Storage, Completely Eliminates Noise

We'll come right out and say it: The Aurender W20 is the most advanced, best-performing, and greatest music server on the planet. Designed for use with reference-grade DACs, and able to playback up to 2x DSD in native form, W20 offers discerning listeners external word clock and master clock support to bring literal mastering-studio-quality sound into your home. The world's first music player to entirely eliminate noise from AC power supplies and AC mains, W20 utilizes LiFePO4 (LFP) batteries to power audio components. This engineering breakthrough is complemented by an All Digital Phase Locked Loop system with OCXO clock to eradicate jitter from the equation. A massive 12TB hard-disk drive stores the most serious music collections while a 240GB solid-state drive gives you the benefits of cache playback. W20 literally has and does everything. 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, W20 comes with a full suite of connectivity to accommodate any conceivable setup. 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 W20 for everyone. But for audiophiles with serious digital-audio systems and that want everything high-resolution offers, there's no finer option. 100% Music Direct Guaranteed.

"It excels in every parameter; its array of features is unmatched; the 12TB of available storage will accommodate virtually any library; its interface is wonderful and intuitive; and most importantly, it delivers sound quality unmatched by any other digital source I've heard."
--Robert Harley, The Absolute Sound, Golden Ear, Product of the Year, and Editors' Choice Awards

"When connected to great components, the W20 enables one to hear into the music – with a low noise floor and clean signal – like nothing else. The flagship W20...is without a doubt the best music server I've used to date."
The Computer Audiophile, Suggested Hardware review

"Aurender has clearly gone to great lengths to ensure that nothing gets in the way of [W20's] most important purpose. It fulfills the role of a single or second source brilliantly without actually playing second fiddle to anything. It is a truly exceptional product. Expensive but very highly recommended."

"One needn't worry about choices of software or hardware, configuration protocols, parasitic electrical noise, or ground-loop effects. Like the top-flight CD players of old, this edge-of-the-art platform is more high-end than the many-headed Hydras of most computer-audio systems. More important, the W20 pulls out all the stops and hits all the right notes of file management and playback."
Soundstage! Ultra, Reviewers' Choice review

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

Jitter and noise seriously affect DAC performance. 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. 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. W20 supports both word clock (dCS DACs or similar) and master clocks (MSB DACs or similar). In addition, W20 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. For example, when Dual AES/EBU mode is used, left and right channel is transmitted at 96kHz rate to make 192kHz stereo transmission. Since the max frequency is halved, transmission line requirement becomes less strict.

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.

12TB Hard-Disk Drive Storage with Solid-State Drive for Cache 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, 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 

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, W20 comes with one a Gigabyte Ethernet port and two USB 2.0 data ports. In addition, W20 hosts a third bank of batteries that acts as an un-interruptible Power Supply (UPS). Should any sudden power outages occur, W20 will shut down safely.

Built to the Extremes: Fan-Less Switching Mode Power Supply and Damped Drives

A fan-less 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. W20'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 W20. All settings and functions of W20 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

W20'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, W20 is able to play music stored on NAS devices. The AMM (Aurender Media Manager) software is available for Mac (OS X 10.9 or later)/Windows7 or later. 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 you 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.
