Aurender A20 Reference Analog Output Digital Audio Music Streamer
DESCRIPTION
The Aurender A20 is a reference-grade, ultra-high-end analog output network player, caching music server, and DAC. It is a streamlined version of Aurender's flagship A30, stripping away the CD-ripping hardware and fixed storage to deliver identical, uncompromising audio performance for audiophiles focused entirely on file streaming and digital music libraries.
- Dual-Mono DAC Configuration: Built around two prestigious AKM AK4497 DAC chipsets powered by discrete, independent linear power supplies for each channel to achieve total channel isolation and an exceptionally quiet noise floor.
- Lossless Preamp & Volume Control: Features a high-quality DAC-level volume control, enabling it to act as a complete digital preamplifier connected directly into power amplifiers.
- FPGA-Based Precision Clock: Uses a Field-Programmable Gate Array system with a sub-100fs jitter-reducing Oven-Controlled Crystal Oscillator (OCXO) to flawlessly time digital data transmission.
- Linear Power Supply with Built-in UPS: Utilizes discrete toroidal power transformers alongside a super-capacitor-based Uninterruptible Power Supply (UPS) to protect the software and storage system from sudden blackouts.
- Dual User-Installable Storage Bays: Features two rear-panel slots accommodating 2.5-inch SSDs or HDDs (up to 16TB total storage), meaning you only pay for storage if you choose to install it.
- Sound Profile: Reviewers from Moon Audio characterize the A20 sound stage as linear, uncolored, and neutral. Rather than presenting artificial warmth or brightness, it provides incredible microdynamics, deep transparency, and realistic spatial imaging.
- Format Capabilities: Fully decodes Master Quality Authenticated (MQA) files natively. It supports PCM files up to 32-bit/768kHz and DSD up to DSD512 via its dedicated USB audio output.
- Critical Listening Mode: Allows listeners to completely defeat the front panel screen and all non-essential internal background computing processes, strictly isolating resources to improve sound quality.
- Analog Outputs: Equipped with premium balanced XLR (selectable up to 5.4 Vrms) and unbalanced RCA outputs.
- Digital Inputs: Includes two Toslink optical inputs, one RCA S/PDIF, and one BNC S/PDIF input for external digital sources.
- Headphone Section: Houses a dedicated, robust headphone amplifier accessible via a front-panel 1/4" jack.
- Control App: Operates through the Aurender Conductor App (iOS and Android), providing seamless library navigation, custom playlist construction, and integrated access to Tidal Connect, Qobuz, and Spotify Connect. It is also certified for Roon integration.
