Discover the Leaders in Portable HiFi Audio

Astell&Kern is a company whose name tells a story. Astell means "star" in Greek, and Kern means "core“ in German. Together, these words refer to the company's aim to continuously reach for the core of music — the "original sound." The name Astell&Kern speaks to the company's obsession with fidelity, ensuring the listener hears music exactly as the artist intended. With modern metals, sharp edges, and sleek designs, Astell&Kern products look like the future. High-end portable audio is something Astell&Kern does exceedingly well, and they have some of the best products out there.

Why Astell&Kern?

Here at Moon Audio, we vet every manufacturer we carry because we want to provide our customers with brands that we support and are proud to use ourselves. Carrying Astell&Kern products was a no-brainer for Moon Audio Owner and Founder Drew Baird, P.E., who says the company's products are reliable, simple to use, and innovative .

"Why Astell&Kern? Reliability, simple to use, innovative, and a great price-to-performance ratio. I actually like that Astell&Kern uses a closed, modified Android operating system. There's always at the forefront of innovation before anybody else. I mean, they were the first digital audio player to come out with a 2.5mm balanced output and now they have transitioned nicely to the 4.4mm, but kept the 2.5mm for folks that purchased a large stash of headphones and IEMs that utilize that connector," said Drew Baird, P.E.

History of Astell&Kern

In 2012, a South Korean home electronics company called iRiver (now known as Dreamus) debuted the AK100 portable media player, an MP3 player for high-resolution audio. It was dubbed an "iPod on steroids." It cost $699, and it prompted questions like, "What does a $700 iPod sound like?" The answer was that it sounded really good, despite its price tag and lack of features like wi-fi. Later that year, after releasing the AKR01 in-ear monitor, iRiver launched Astell&Kern as a subsidiary.

"We use the power of music to change your life." -Astell&Kern

Astell&Kern is dedicated to delivering best-in-class high-resolution audio devices for the playback of MQS (Mastering Quality Sound) studio-quality audio. Combining design and engineering excellence, craftsmanship and high-quality materials with state-of-the-art audio technology, Astell&Kern's range of award-winning portable music players and IEMs deliver the ultimate listening experiences.

What Makes Astell&Kern Different?

Astell&Kern products stylistically stand out from the crowd with their modern metals aesthetic, sharp edges, and sleek designs. AK digital music players look like the future. The company is best known for portable high-end music players, or hi-res “iPods.” As consumers learn about the need for higher resolution music files to feed our high-quality media players, those made by Astell&Kern have thrived.

We think Astell&Kern makes some of the best music players in the world. Plus, their technology is easy to learn and navigate as a newbie or a technology wizard. If you love to listen to music “on the go” and want hi-fi sound, AK digital audio players (DAPs) are essential listening gear with Mastering Quality Sound (MQS).

MQS includes high-resolution digital music recording formats from 16-bit/44.1kHz to 24-bit/192kHz. Sound engineering tech-speak can be confusing. More is usually better. Higher amounts of information can mean better sound with crisper highs and fuller lows (bass). The trick is to process and play as much information as possible or as much information as your recordings started with in the first place. Playing all the high-res information captured during the music recording process is Astell&Kern’s expertise.

Astell&Kern Technology

TERATON ALPHA

TERATON ALPHA is AK's ultimate Sound Solution to produce audio playback that is close to the original sound through the use of effective power noise removal, efficient power consumption and amplification without compromise through the audio output interface.Many people think “It is the DAC that determines the sound in the DAP, and in the end, if you use the same DAC, the sound will be similar for each product.” The DAC does play a large part of the sound signature in a DAP, but it's not the only factor that determines the level of sound.

DAPs can be largely divided into three sections: power, amplifier, and interface.

  • Power: Astell&Kern's audio technology effectively removes power noise and converts the signal, which is essential to the power of the audio.
  • Amplifier: The reason why the same DAC produces different sound signatures is because of differences in amp design. A&K's advanced AMP technology features efficient power consumption and powerful amplification that delivers performance without compromise.
  • Interface: The audio interface that converts digital signals to analog and outputs then is composed of technology developed by AK that has been enhanced over the years.

TERATON ALPHA features Astell&Kern's patented technologies that are the result of tens of thousands of hours of continuous research and development to produce sound close to the original sound the artist and producer intended.

Roon Endpoints

For those who enjoy streaming with Roon, the good news is that newer AK players are Roon Ready.

What is Roon? Roon is a rich and engaging way to browse, organize, and listen to music. Artist photos, credits, bios, reviews, lyrics, tour dates, and composers are located automatically and then interconnected by links to build a surfable digital magazine. Roon is also a multi-room, multi-user networked audio platform offering features such as bit-perfect playback, DSD and PCM upsampling, multichannel support, and Signal Path display.

What is Roon Ready? Roon Ready network devices have Roon's streaming technology built in, and are certified by Roon Labs to provide the highest level of quality and performance in network streaming. Being Roon Ready means that Astell&Kern players transparently discover and connect to Roon without any configuration, and bit-perfect audio is delivered from Roon to the player. This allows you to stream music from your device using Roon as your music management and playback engine.

Astell&Kern BT SINK

BT Sink allows you to connect your AK player to an external device via Bluetooth, similar to connecting a smartphone to a BT speaker. This allows you to access your local music library and play it at the highest available codec. For instance, if you have music stored locally on your phone or laptop and want to access said library that might not be your music player, you can connect it to the AK player for immediate file playback though the DAP itself via Bluetooth sync (or BT Sink).

How To: Astell&Kern BT SINK

AK File Drop

AK File Drop makes wireless file transfers simple. Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program on the same network. Music file management is now possible with a wireless solution. Whereas BT Sink can stream your music from another device, AK File Drop can actually transfer those files to local storage on your device.

SP3000 DAP Music Player - 24K Gold Edition

The Astell&Kern SP3000 DAP 24K Gold Edition is a nod to the success of the SP3000 DAP, possessing the same sound quality and technology but with a 24K gold-plated chassis. This is a limited edition model that captures the sound of the SP3000 in a chassis of extreme luxury and value.

Headphones & IEMs

Popular with performing artists and audiophiles, in-ear monitors, or IEMs, are a fantastic option for people who want the fidelity of full-size headphones with the portability and convenience of earbuds. While Astell&Kern is primarily known for their digital audio players, they have come out with several fine IEMs over the years that echo the design elements and sound quality of their DAPs. Astell&Kern has teamed up with other audio manufacturers for many of their IEMs, including Empire Ears, JH Audio, Beyerdynamic, and Campfire Audio. They also collaborated on a full-size headphone with Beyerdynamic.

AK ZERO1 In-Ear Monitors

The AK ZERO1 was the first fully in-house IEM endeavor for Astell&Kern. It's a tribrid design, combining a planar magnetic driver, two balanced armature drivers, and a dynamic driver. The AK ZERO1 IEM focuses on combining the sounds of three unique driver technologies into one IEM. The AK ZERO1 harmonizes the characteristics of each driver to deliver the most natural sound to your ears. An ideal frequency response was created through the crossover network, which is designed based on a thorough understanding of each driver’s parameters. At the same time, each driver is carefully placed in the optimal 3D position, enclosed in specifically designed acoustic chambers manufactured with precise 3D printing technology. By implementing this, Astell&Kern eliminated unnecessary movement and resonance of the drivers to ensure a stable performance.

Sound: Neutral, Musical

Standout Genres: Rock, Metal, R&B, EDM

PATHFINDER In-Ear Monitors

The hybrid PATHFINDER is an Astell&Kern collaboration with Campfire Audio. Featuring a "mountain peak" inlay design, the PATHFINDER combines AK's "light and shadow" design philosophy with Campfire's "awe of nature" design philosophy. Featuring a warm and rich sound, the PATHFINDER has a new Dual-Chamber Balanced Armature (BA) Driver from Knowles for the key part of the midrange, two BA drivers for high frequencies, as well as two dynamic drivers with a hybrid diaphragm that create bass and midrange. Knowles’ new ‘Dual Chamber’ Balanced Armature Driver, used for the first time ever in PATHFINDER, is an innovative driver in which a single coil operates two individual diaphragms. It’s like a twin cylinder engine – delivering more horsepower and smoother operation compared to one with a single, larger piston.

ACRO CA1000 Desktop DAP Music Player

The ACRO CA1000 is a product that breaks boundaries. It's a headphone amplifier and DAC - four ES9068AS DACs, to be precise. But it's also a DAP! AK calls it "carryable" because you can easily transport it. It's portable in the sense that there is no external power source, so you're never tethered to an outlet. The built-in battery provides 10-plus hours of playback, and the battery is fully charged in 2.5 hours. The tilting display can be adjusted to an optimal position depending where it is placed on your desk or table. The CA1000 supports four levels of gain settings so you can drive any headphone, including the most power-hungry. HiFiMan SUSVARA? No problem! The ACRO CA1000 can be used as a Hi-Fi audio system by connecting devices using a variety of digital inputs/output (Optical, Coaxial, Type-C USB) and analog inputs/outputs (RCA). And you get 2 balanced and two unbalanced headphone outputs.

Dragon Audio Cables

Audio cables are the icing on your audio cake, and they can make or break your listening experience. At Moon Audio, we craft custom cables to improve the sound of your headphones and other audio gear. Your choice of cable is going to depend on a couple of factors, the first being the sound signature of your DAP. We recommend the Silver Dragon Headphone Cable for warmer DAPs and the Black Dragon Headphone Cable for more analytical-sounding DAPs. That being said, the sound signature of your headphones is also going to be a factor. Bottom line: If you are looking to add weight and warmth to the overall sound, or if you want a smoother top end, go with the Black Dragon. If you are looking for more detail, clarity, and top-end sizzle, go with the Silver Dragon.

Our HiFi Dragon Audio Cables bring out more of what you love in your music and audio gear. If your USB cables keep dying - as many stock cables do - then check out our quality USB Audio Cables. We say time and time again that materials matter, and our audio cables and custom geometries actually help to bring out those desired properties in your gear and music. We make tons of custom options for our customers so that you can get the right HiFi Audio cable for your exact needs. If you have any questions feel free to Contact Us and we'll be more than happy to help.

Generally, stock audio cables are manufactured with subpar materials, metals with impurities, poor geometries, and an overabundance of layers to make them look and feel like a fire hose. Inconsistency and lack of quality control in stock cables can lead to poor sound quality and a veiled sound vs. what the musician intended for you to hear and feel from the music. Dragon Audio Cables are handcrafted with the highest standards and made to order according to your specific needs. At Moon Audio, we create a custom cable for you using the highest quality UP-OCC silver or copper conductors that can be manufactured. UP-OCC metals are void of impurities and are optimized for signal transfer and sound quality. We have one of the largest collections of audio and headphone connection options available online and we create limitless audio cable options depending on your specific gear and needs.

Why Dragon Cables?
You’ve heard the saying that a chain is only as strong as its weakest link, right? Well, the same applies to your brand new audiophile-grade headphone or other audio components. The weakest link, in this case, is your stock audio cable or the cheap interconnects the manufacturer threw in the box just to get you up and running. Why is the audio cable always an afterthought, when it’s just as important as the rest of your system? At Moon Audio, we use the purest and best raw materials in our cables to unveil your music. We believe that materials matter and your audio cables should have the same care and craftsmanship that manufacturers put into their audio components and headphones. Audio cables are ultimately the connection to your music. The fact remains that cabling is often considered the last priority to that of the main product and a means to cut down the overall production costs. It’s as simple as that. Dragon Cables elevate every note - as if you were hearing your favorite music for the very time.
