Aurender W20SE Reference Music Server and Streamer

In the rarified air of state-of-the-art digital audio, the complete elimination of noise is the ultimate goal. The Aurender W20SE is a component born from this singular pursuit, a Special Edition reference music server that employs a radical solution: pure, battery-powered playback. By completely isolating the sensitive audio output stage from the noise and distortion of AC power, the W20SE achieves a level of purity and background silence that is simply unattainable by conventional designs. Combined with a state-of-the-art OCXO Rev2 clock, a unique Dual-AES/EBU output for high-resolution transmission, and a massive 1TB caching SSD, the W20SE is the definitive digital source for the listener who demands an unfiltered, uncompromised connection to the music.

Key Features

• Battery-Powered Audio Stage: A revolutionary design featuring three LiFePO4 battery packs to completely isolate the audio circuitry from AC power noise during playback.
• OCXO Rev2 Clock: A new, ultra-high-precision Oven-Controlled Crystal Oscillator delivers a stable, ultra-low jitter reference for unmatched timing, rhythm, and musical flow.
• Dual-AES/EBU Digital Output: A unique output that can transmit high-resolution PCM (up to 384kHz) and DSD (up to DSD128) over two AES/EBU cables to compatible DACs.
• External Master Clock Input: A 75Ω BNC input allows for connection to an external master clock for the absolute pinnacle of system synergy and timing accuracy.
• Massive 1TB Caching SSD: An enormous 1TB NVMe solid-state drive is used as a cache for playback, ensuring completely silent operation.
• 16TB Internal Storage: Comes with a massive 16TB enterprise-grade HDD pre-installed to house the most extensive music libraries.
• Double-Isolated LAN Port: Provides a clean, noise-free signal path from your network to preserve the full integrity of the audio source.
• Comprehensive OCXO-Controlled Outputs: A full suite of digital outputs, including Dual-AES/EBU, Coax (BNC & RCA), and Optical, are all governed by the master OCXO clock.
• Dedicated Low-Noise USB Output: A dedicated, isolated USB Audio Class 2.0 output delivers a pristine, noise-free signal to your DAC.
• Dual 3.7" AMOLED Displays: Two beautiful, sharp front-panel displays show track information and system status.

The Purity of Battery Power

The W20SE’s most radical and effective feature is its revolutionary power supply. During playback, the entire audio output stage is powered exclusively by a clean, silent bank of LiFePO4 batteries, completely disconnecting it from the AC mains. This heroic approach eliminates all potential for power-line noise, RFI, and EMI to contaminate the delicate digital signal, creating a profoundly black background from which music emerges with startling purity and realism. The batteries are intelligently charged only when the system is not in playback, ensuring that your listening sessions are always powered by pure, off-the-grid DC.

The Heartbeat of the Music: Precision Timing

In digital audio, timing is everything. The W20SE employs Aurender's state-of-the-art OCXO Rev2 clock, a reference-grade oscillator that provides a timing reference of breathtaking precision, virtually eliminating the jitter that can smear detail and flatten the soundstage. The result is a sound that is rhythmically coherent and effortlessly natural, with a sense of musical flow that is truly captivating. For those seeking the absolute pinnacle of system synergy, a 75Ω BNC master clock input allows the W20SE to slave to an external master clock, achieving an even higher level of temporal accuracy.

The Ultimate Digital Connection: Dual-Wire AES/EBU

For owners of compatible high-end DACs, the W20SE offers a unique and sonically superior connection method: Dual-Wire AES/EBU. By using two separate AES/EBU cables, the W20SE can transmit high-resolution PCM signals up to 384kHz and DSD signals up to DSD128 (via DoP). This method provides a more robust, lower-jitter connection for high-resolution formats than a single AES/EBU link, ensuring that the maximum amount of musical information is delivered to your DAC. It is the definitive connection for the listener who demands the highest possible performance.

A Library Without Limits

The W20SE is built to be the comprehensive, authoritative home for even the largest and most ambitious music collections. It arrives with a massive 16TB of internal storage, ready to house tens of thousands of albums. When you select music for playback, it is first copied to the enormous 1TB NVMe caching SSD. This means that during your critical listening sessions, the mechanical storage drive is completely dormant, eliminating all acoustic and electrical noise. All of this power is controlled through the acclaimed Aurender Conductor app, a rich, intuitive interface that makes managing your vast music library an absolute joy.
