 Reference Analog Output Network Player MQA Full-Decoder DAC / Headphone Amplifier 2 x Slot for 2.5" HDD or SSD Drive (user-installable) Variable-Output Balanced XLR and Single-Ended RCA Analog Outputs USB Digital Output / Coaxial and Optical Digital Inputs

Flagship sound with Aurender's best DAC built-in.

Reference Analog Output Network Player with Aurender's best built-in DAC, dedicated Headphone Section, User-Installable Storage Options, XLR, and RCA Analog Outputs

 

A20 is derived from A30 and delivers the very same reference-level audio performance but without the CD ripping and library management functionality. A20 also replaces A30’s factory-fitted 10TB HDD with two user-accessible bays to install one or two 2.5” HDDs or SSDs for the music storage capacity needed or desired.

Employing the same renowned dual-mono AKM 4497 chipset as that found in model A30, you can expect nothing but the best in sound quality. A20 is ideal for the user seeking exceptional audio performance from files and streams without the fuss or complexity of separate components.

A20's scaled-back design makes no compromise where audio performance is concerned. Music lovers who have no need for CD-ripping functionality and want a high-end DAC without adding more boxes will find the A20 to be a stellar foundation for any 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, the 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 "supercapacitor" based UPS system stabilizes A20 in the event of an abrupt loss of power.
Dedicated Headphone Section
In addition to being a stellar Analog Output Network Player for loudspeaker systems, the 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.
FPGA-Based Precision Clock
A20's precision clock generation system incorporates a Field-Programmable Gate Array (FPGA) with a 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 amp! A20's DAC-level lossless volume control enables it to function as a preamp when connected directly to a power amplifier.
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 CD transport, TV, etc. Any device connected this way will take full advantage of the superior sound quality of the DAC within the A20.
