Aurender A15 – High-End Audio Streaming and Serving

Immerse yourself in a musical experience like never before with Aurender’s A15, the future of high-end audio streaming and serving. Forging a lasting impression on digital music technology following our lauded A10 model, Aurender now elevates the audio landscape with the advent of the A15—a music server/streamer/DAC that leverages state-of-the-art features and remarkable enhancements in audio quality to deliver a listening experience that rivals live performances. Through its innovative design, the A15 expertly consolidates the functions of a dedicated streamer and standalone DAC, eliminating the opacity and high costs associated with conventional system setups. Its heart— a high-performance, dual-mono AKM4490 DAC integrated with MQA full-decoder technology— allows smooth and detailed audio translation, supported further by balanced (XLR) and unbalanced (RCA) analogue outputs. The A15 also features two rear panel bays for easy installation of 2.5″ HDDs or SSDs, enabling mass storage of your music library. Its vibrant full-colour front panel encapsulates the essence of your melodies via vivid album art display, further enhancing the user’s connection with the music. Features:

1. Dual-Mono MQA Full-Decoder DAC: The A15 boasts a dual-mono layout of the recognized AKM4490 DAC chipset, refining audio performance, channel separation, dynamics, and noise floor reduction for optimal sound quality.
2. FPGA-Based Precision Clock: The device incorporates a highly precise clock generation system that considerably lowers jitter levels, ensuring flawless digital audio data transmission.
3. Linear Power Supply: The A15’s fully-linear power supply includes four high-quality toroidal transformers and advanced shielding and isolation to prevent noise interference.
4. Versatile Connectivity: The A15 can function as a sound source or a preamplifier, making it both adaptable and straightforward to use. It can be connected directly to a power amplifier or an active speaker system.
5. Flexible Digital Inputs / Output: The device comes with both a coaxial (RCA) and an optical (TosLink) digital input for maximum flexibility and improved audio fidelity.
6. High-Resolution Streaming and File-Based Content: The A15 supports all widely-used file formats like DSD, WAV, FLAC, AIFF, ALAC, M4A, APE, and MP3, ensuring none of your favourite tunes get left out.
7. Adaptive File Library Storage: The device comes with two user-accessible storage bays that can accommodate both SSDs and traditional HDDs, offering up to 16TB of storage space.
8. Cache-based Playback: All playback happens from an internal solid-state cache, curbing possible electrical and acoustic noise and enhancing the overall audio performance.
