Redefining the relationship between Digital Audio and Music
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 A20 to be a stellar foundation to 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, A20 delivers MQA full-decoding to get the best performance out of MQA content, as well as every other major digital audio format.
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.
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.
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.
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.
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.
Four digital inputs are provided: one RCA Coax, one BNC Coax and two Optical. These inputs allow 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.
Hallmarks of Aurender
Hardware <> Software Integration
A closed system. Aurender playback and control software is developed in the same building as its hardware. Superior integration means that Aurender's software engineers are able to specifically optimize playback performance of the extremely robust hardware at their disposal.
Caching Playback Engine
Other systems buffer. Aurenders cache. Every Aurender model features a massive solid state memory from which all playback occurs. This important feature helps to minimize system resource requirements for enhanced audio performance and stability.
Dedicated USB Audio Output
USB is prone to transferring noise between devices. Aurender's dedicated USB Audio output is physically and electrically isolated from the noise-generating CPU board to minimize noise in the sensitive audio interconnect.
Low-Power High-Efficiency CPU
A powerful CPU is essential to making any computer run smoothly and quickly. However, with more power comes more noise. Aurender's low-power high-efficiency Intel CPUs have enough headroom to run the machine while minimizing the amount of current drawn in order to keep the noise floor as low as possible.
Elegant Front Panel Display
Easy to read high resolution LCD display. Dynamic, elegant, understated.
Double Isolated LAN Port
Two layers of transformer based isolation to filter noise out of Ethernet connection.
Local Library Storage Capacity
Every Aurender contains either massive built-in internal storage capacity, or at least one slot for super easy user-installable storage options. Enjoy localized media storage, and ditch the cumbersome NAS or HDD.
Integrated Streaming Services
The entire world of streaming music content is available to you within one great app. Enjoy integrated access to TIDAL, Qobuz, and Internet Radio. Plus Spotify Connect and AirPlay.
Critical Listening Mode
Enable Critical Listening Mode to defeat the front panel screen, buttons, and all background computing activity that is not essential for playing music. CLM offers an even quieter, more transparent audio presentation.
USB HDD and NAS Connectivity
The best user experience occurs occurs when your music content is stored on Aurender’s internal storage. However, USB 3.0 data ports and NAS share connectivity are included in order to play or import content stored on a NAS, external USB hard drive, or thumb drive.
Support for All Major Audio Codecs & Formats
Remote Internet Technical Support
In case you should encounter any difficulty or problems, Aurender's dedicated support team may log into your system remotely to diagnose and fix any issues. We take support extremely seriously, and we're here to help!
