Aurender A20
Redefining the Relationship between Digital Audio and Music
The A20, derived from the A30, delivers reference-level audio performance without the CD ripping and library management functionality. Unlike the A30, the A20 features two user-accessible bays, allowing the installation of one or two 2.5” HDDs or SSDs for customizable music storage capacity.
Employing the renowned dual-mono AKM 4497 chipset, also found in the A30, the A20 ensures the best sound quality for users seeking exceptional audio performance from files and streams, minus the complexity of separate components.
The scaled-back design of the A20 makes no compromise on audio performance. It is an ideal choice for music enthusiasts who do not require CD ripping functionality and desire a high-end DAC without adding more boxes to their setup. Make the A20 the stellar foundation for your audio system.

Aurender’s Best DAC
Aurender designed the A20 for those seeking the simplicity of an all-in-one unit without sacrificing a high level of resolution, transparency, and the reproduction of inner detail. Built around an integrated dual-mono AKM4497 DAC module, A20 delivers MQA full-decoding to get the best performance out of MQA content, as well as every other major digital audio format.
Linear Power Supply with Integrated UPS
A fully-linear power supply architecture with extensive shielding prevents noise from being delivered to sensitive DACs. Four discrete toroidal transformers power the server system, digital outputs, and dual-mono DAC respectively. A “super capacitor” based UPS system stabilizes A20 in the event of an abrupt loss of power.
FPGA-Based Precision Clock
A20’s precision clock generation system incorporates a Field-Programmable Gate Array (FPGA) with sub 100fs jitter-reducing clock generator to precisely time digital audio data transmissions and minimize jitter to below negligible levels.
Variable Output XLR & RCA Outputs
A20’s high-quality Balanced (XLR) and Unbalanced (RCA) outputs guarantee compatibility with any preamp, integrated amp, or even power amps! A20’s DAC-level lossless volume control enables it to function as a preamp when connected directly to a power amplifier.
Dedicated Headphone Section
In addition to being a stellar Analog Output Network Player for loudspeaker systems, A20 also features a 1/4″ headphone output for quiet times.
Upsampling DAC Option
A20 is capable of upsampling non-DSD files up to 705.6/768kHz to the analog outputs. Or leave upsampling off (default setting) for an untouched bitstream.
User-Installable Storage Options
A20 is built with two trays for user-installable storage. Need a lot of capacity? Load up to 2 8TB SSDs! Not into storing files and prefer to stream? Leave them empty, and don’t pay for storage capacity you won’t use.
Digital Connectivity
Four digital inputs are provided: one RCA Coax, one BNC Coax, and two Optical. These inputs allow the connection of additional digital sources such as a CD transport, TV, etc. Any device connected this way will take full advantage of the superior sound quality of the DAC within the A20.
