Wireless Streaming Amplifier

From digital to vinyl, music file to online streaming, POLARIS is everything you need to unite your musical world — without the racks and interconnects of traditional multi-component systems. The POLARIS brings together technologies that made our standalone components game-changers in the audiophile world, for an all-in-one audio system with an award-winning pedigree. Flexible and powerful, with the POLARIS you’ll discover that convenience doesn’t have to mean compromise anymore.


Modern Features. Classic Hi-Fi. One box.

In 2014 the AURALiC ARIES and ARIES MINI brought high-resolution Wi-Fi streaming to High-End audio. Now we’ve coupled that industry-leading technology with all the functionality of an entire home audio system to create an amplifier that’s ready for anything. The POLARIS is a high-performance streamer, a world-class DAC, a digital music server, a pre-amplifier and a 180-watts-per-channel power amplifier the can handle the most demanding loudspeakers. With the ease of a single box, the flexibility of an entire system, and the uncompromising quality of AURALiC’s award-winning engineering, the POLARIS has the power to breathe life into everything you listen to.

The Art of High-End Streaming

We developed Lightning OS to be the highest-quality streaming environment you’ve ever heard. A meticulously-crafted software architecture designed specifically to work hand-in-hand with the powerful Tesla hardware platform found in AURALiC streaming products, Lightning OS is full of cutting-edge innovations that bring your music to life like never before. Connect to all your high-resolution sources, take control with user apps like Lightning DS or Roon, and meet true audiophile streaming.

Connect... to Everything.

The POLARIS is ready for every type of digital sourcing available with a host of physical ports, from USB to TOSLINK, AES/EBU and more. But there’s another trick up this unit’s sleeve: two pairs of high-end, multi-function analog RCA connectors that can be configured for pre-amplifier output duties, line-level input, or phono input to take advantage of the POLARIS’ built-in phono stage. Add native integration of AURALiC’s Lightning OS and your system opens up to the world of high-resolution streaming from network and online streaming like TIDAL, Qobuz and Internet Radio. A RoonReady endpoint with support for AirPlay, SongCast, and Bluetooth, the POLARIS is the missing link that finally unites all the ways you listen to music.

Impeccable Credentials

From digital conversion to power amplification, the technology behind everything the POLARIS can do is inherited from our line of industry-leading standalone components. Its DAC uses innovative designs that made the VEGA a standout. Elements from our game-changing ARIES Wireless Streaming Bridge are found in the POLARIS, and its output uses circuitry built for our original MERAK monoblock amplifiers. Years of striving for the best sound quality to be had from modern techniques comes together in a product that’s as serious about sound as you are.

Power for Every Style

We know there are as many beloved speaker designs as there are musical styles to play through them. That’s why we gave the POLARIS the power to handle everything from bookshelves to mega-floorstanders — 180 watts-per-channel to drive even the most demanding models out there. Sonically the POLARIS gets its know-how from advanced amplification and analog output circuit designs originally developed for our very own MERAK monoblock power amplifiers. The result is an expansive output signal with exceptional clarity and definition that’s sure to get the best from your favorite speakers, no matter which style you choose.

Tesla G1

Scalable Power, Custom-Built for Streaming Audio

Our Tesla G1 hardware platform is the processing engine that gives the POLARIS the power and flexibility it needs to meet the demands of modern high-resolution streaming. Designed around a high-performance Quad-Core Cortex-A9 processor running at 1GHz, Tesla G1 sports 1GB DDR3 RAM and 4GB of storage. Automatic updates keep the Tesla G1 platform outfitted with the latest features and support, so your device is always ready for peak performance and up-to-the-minute functionality.

Femto Clock

Based on 120 femtosecond cycles, this extremely precise clock keeps a tight reign on timing for less jitter, and better sound. It’s capable of adjusting frequencies for varying sampling rates too, and with a dedicated low-noise 9uV power supply it’s just as quiet as it is accurate. A specially adapted aerospace-grade crystal is the beating heart that gives our 120 Femto Master Clock its impeccable rhythm.

Flexible Filter

Flexible Filter Mode gives you a nuanced level of control over your audio output. Its four filter modes were developed using a combination of objective data models and subjective testing, with each mode offering a unique array of filters to match the sonic quality of the source. Whether it’s modes to tweak in-band ripple, out-band attenuation, ultrasonic filtering and more, you’ve always got the power to dial in the performance you want.


The Purer-Power linear power supply reduces DC current noise by as much as 90dB with its power purification module. Using a specially designed transformer and unique wiring that minimizes vibration, noise from Purer-Power is kept below 1uV across the audible spectrum, leaving you to discover the details in your music, down to the last bit.

Hybrid Volume Control

Maximizing Performance at Every Listening Level

With the POLARIS, AURALiC introduces one of our newest technologies: Hybrid Volume Control. It’s a feature that combines analog and digital volume controls to optimize sound quality at every level. Analog attenuators modify volume in 12dB steps while digital volume control handles smaller changes within each step. It’s an approach that ensures the DAC chip in the POLARIS is always operating in its peak performance range, lowering distortion and providing better dynamics and sounds quality even at low volumes.

Press Awards

"To me they are a musical metaphor for the POLARIS simple seeming as a Duo (Or single box audio device), but once you get into it you can enjoy the breadth without strain. Bravo AURALiC! Highly recommended."

Eric Neff - HiFi+

"These four points are what newcomers need to know and what the audio(phile) world needs more of: decent sounding gear that doesn’t look like a science project. To this end, the AURALiC Polaris is the epitome of Future-Fi. It’s all we might ever need. What a result! Super indeed."

John Darko - DigitalAudioReview

When it comes to integrated amps, that can mean sacrificing some aspects of sound quality for specific streaming features, or the ability to connect, say, a turntable. But listening to Auralic’s Polaris wireless streaming DAC-integrated, I didn’t feel I was missing anything. Its menu of streaming capabilities and connectivity options are about as complete as I’ve seen on a hi-fi component. And its sound quality was equally impressive, blending power, detail, and warmth in equal measure.

Al Griffin - SoundStage! Simplifi

"Innovative Technik, tolle Ausstattung, wunderbare Benutzerfreundlichkeit und schließlich tollen Klang bringt der Polaris gleichermaßen mit und soll damit als Vorzeigeprodukt von Auralic gelten. Hoch gesteckte Ziele also, doch der Ehrgeiz der chinesischen Entwickler wurde belohnt. Wer auf der Suche nach einer schlanken, flexiblen und gleichzeitig hochwertigen Allroundlösung ist, sollte sich vom Nordstern den Weg weisen lassen."

Philipp Schneckenburger - einsnull

"Der Auralic Polaris ist eine moderne All-in-One-Lösung: Er arbeitet als Streamer, DAC und Vollverstärker mit Phono-Vorstufe – und mit optionaler Festplatte auch als Musikserver. Dabei bietet der Polaris eine Komplettausstattung mit allen digitalen Schnittstellen und offeriert dazu zwei Analog-Eingänge mit Doppel-Funktion.Für so ein Komplettangebot und eine derartige Performance ist der Preis absolut gerechtfertigt. Denn der Auralic macht alles – und er macht alles richtig."

Volker Frech - lite magazine

"Der POLARIS definiert exemplarisch den Anspruch der Marke Auralic: Modernste Technologie, hervorragende Verarbeitung, extreme Vielseitigkeit, ein vernünftiger Preis und großartiger Klang in einem Gerät. Der POLARIS ist ein toller Allrounder. Er weckt auch angesichts des Preises Begehrlichkeiten, da er musikalisch packend und ehrlich klingt."
