The KANN Ultra is Astell&Kern's most powerful music player to date, capable of driving virtually every headphone on the market, including high-demand models like the Dan Clark AEON Noire, Stealth, and Expanse. Its true discrete separate pathway for line-out makes it an ideal source for your two-channel home system or a portable amp like the Cayin C9, which can bypass its preamp stage. This means the KANN Ultra can serve as an affordable alternative to high-end Cayin DAPs, acting as a dedicated preamp/source for top-tier amplifiers like the C9.
Designed for those who need power on the go, the KANN Ultra excels at driving full-size audiophile-grade headphones, making it perfect for planar magnetics where increased power output translates to enhanced sound quality and fidelity. The flagship-level DAC chips deliver stunning audio, and with four levels of gain and substantial power, your music will have everything it needs to shine.
What sets the KANN Ultra apart is not just its increased output but also the addition of pre and line-outs. This provides a plethora of options for integrating the player into your system, whether it's a portable setup, a small-form desktop configuration, or a full-blown desktop setup as a standalone music source. Astell&Kern has consistently excelled in offering versatility, allowing you to enjoy your music how and where you want, without being limited to just a headphone setup on the go.
Dragon Cable Recommendation: We recommend pairing the Astell&Kern KANN Ultra DAP with our popular Black Dragon USB Audio Cable . The Black Dragon USB cable utilizes our single crystal UP-OCC copper construction to provide you with the best possible digital bus transmission. Our Black Dragon USB cable will bring an extraordinary amount of detail and resolution to your hi-fi system. The Black Dragon USB cable is designed to transfer digital audio from your source device (like a computer, phone, tablet, or digital audio player) to a USB-capable DAC. It is built to USB Audio specs. The Black Dragon USB Cable is meant for audio data transfer only - meaning that this cable should not be used for high-speed data transmission (via external hard drives). Because of the high-quality materials and cable geometry, Dragon USB cables greatly reduce stock USB cable issues such as packet loss and jitter.

Plenty of Power for Your Music
The KANN series is beloved by audiophiles worldwide for its ultra-high output and crystal-clear sound. The KANN ULTRA, the fifth product in this acclaimed series, builds on this legacy with the highest output of any Astell&Kern player, featuring Triple Output Sound and an optimized processor and UI/UX for an enhanced listening experience. With four gain modes delivering up to 16Vrms of desktop Hi-Fi level output and powered by ES9039MPRO Dual DAC chips, the KANN ULTRA effortlessly drives today's high-resolution headphones. Additionally, its separate Pre/Line Out functionality allows users to connect and enjoy a variety of different audio devices.
Triple Output, Triple Sound
The KANN ULTRA features a Triple Output Mode, enabling you to experience Astell&Kern's meticulously crafted sound with demanding headphones, highly detailed IEMs, and external devices. Instead of merely separating the output ports, Astell&Kern's Teraton Alpha technology provides distinct amplifier and sound designs for the Headphone Out and Line/Pre-Out ports, ensuring optimal sound quality for each connection. With the KANN ULTRA's Triple Output, you can complete your powerful Head-Fi system even on portable devices.
*Headphone Out 3.5mm Port: S/PDIF Out Supports
1. Headphone Out: The port features 4 preset gain settings and ultra-high output of up to 16Vrms. The headphone port is designed to perfectly run demanding headphones with high impedance using only the player with no external AMP.
2. Pre-Out: Select Pre-Out mode on the Pre/Line Out port to output sound to an external amplifier or audio device. This mode delivers sound through a specially designed Pre-Out amplifier, instead of the high-powered Headphone Out amp. Pre-Out functions like a Pre-AMP and you can control the volume with the volume wheel.
*No Gain or Voltage settings, maximum output 2Vrms/4Vrms
3. Line Out: Select Line Out mode on the Pre/Line Out port to output sound that is optimized when connected to external devices. This mode outputs the sound from the DAC directly without going through an amplifier, resulting in the lowest noise level and making it ideal for connecting to external audio devices. Line Out has a fixed voltage output (4 levels) and no volume control.
4 Gain Levels and Outputs up to 16Vrms for the Perfect Head-Fi
To power the most sophisticated IEMs and headphones, a DAP needs to deliver output that matches the receiver's characteristics. The KANN ULTRA excels in this with its four preset gain settings, offering up to 16Vrms—the highest output of any Astell&Kern player—ensuring optimal performance for today's diverse IEMs and headphones. The output port's current-handling capability has been enhanced to reliably power devices with varying impedances at any gain level. Additionally, the AMPs are separated into Balanced and Unbalanced, optimizing currents and reducing noise for superior sound quality. Beyond its powerful output, the KANN ULTRA boasts a larger 5.5-inch screen and an improved grip compared to the popular KANN CUBE. Despite its capabilities, the KANN ULTRA is lighter, weighing in at just 390 grams.
TERATON ALPHA, The Essence of A&K Audio Technologies
Astell&Kern's TERATON ALPHA technology is the key to the ultra-high output and intricate amplifier design with minimal noise in the compact KANN ULTRA portable audio player. This advanced technology enables the player to power even the most delicate headphones while supporting the Triple Output design.
Drawing on expertise in noise reduction at ultra-high power from previous models like the KANN MAX and the CA1000 series, Astell&Kern has further refined TERATON ALPHA. This proprietary technology is engineered through continuous research to deliver audio playback as close to the original sound as possible. It achieves this through effective power noise removal, efficient power management, unwavering amplification, and a fully converted audio output interface.
Upgraded Sound, the Newest ESS Flagship DAC
The KANN ULTRA is equipped with dual ES9039MPRO DACs, the latest flagship DACs from ESS, providing a richer and more expansive sound that surpasses expectations. The ES9039MPRO, an updated version of the ES9039PRO, features a built-in stereo hardware MQA renderer and advanced modulation to reduce power consumption, noise, and distortions, enhancing audio performance.
Astell&Kern has meticulously redesigned the AMP BLOCK to ensure that the ES9039MPRO's clear, high-resolution sound is accurately expressed through every port of the Triple Output. Each output showcases its unique, advanced performance characteristics, delivering exceptional audio quality across the board.
Incredible User Experience With Next-Generation Octa-Core Porcessors
The KANN ULTRA is the first to feature next-gen Octa-Core processors, delivering significant performance improvements for faster system speeds and a smoother, more responsive 4th generation UI/UX. This ensures you can fully enjoy the incredible sound performance of the KANN ULTRA.
To maintain optimal audio quality, the audio circuit area is physically separated from the processor area, which includes the CPU, memory, and wireless communication components. Additionally, a dedicated shield can is equipped to minimize heat and noise generated by the processor, ensuring the purest sound experience.
Crimson User Interface, A Music-Only Player
The KANN ULTRA debuts a Crimson-themed UI/UX, making it a standout "Player for Music" that enhances the entire listening experience. The Crimson UI/UX allows users to effortlessly browse music categories and rediscover songs within their library. An easy album art search function adds to the joy of viewing and interacting with album art while listening to music.
The crimson theme emphasizes simplicity and edge, featuring a dark mode with black and red highlights to reduce visual fatigue and provide an intuitive user experience. It also includes numerous improvements to the device’s user-friendliness, such as better streaming app integration, enhanced artist view, refined album sorting, and an improved album art search function. Immerse yourself in music with the Crimson UI/UX.
Craft Your Own Sound with DAC Filters
With the KANN ULTRA, you can pick and choose from seven DAC filters to create your own sound style. Design your own sound with the seven DAC filters.
Digital Audio Remaster Technology for Even More Vivid Original Sound
The KANN ULTRA is equipped with Digital Audio Remaster (DAR) technology, designed to deliver refined sound at higher sample rates. DAR technology upscales the sample rate of the audio source beyond its original format, allowing for more detailed playback and an analog-like sound quality. This enhances the richness and subtle nuances of the music, providing a fuller, more immersive listening experience.
*The DAR function can be toggled on or off to suit the source audio and your personal preferences. *It supports a maximum PCM rate of 384kHz and DSD256 conversion, with files being converted and played at sample rates that best match the source sound.
Crossfeed, Speaker Effect When Listening Through Headphones
In a headphone setup where left and right channels are distinctly separated, prolonged listening can lead to ear fatigue. By activating Crossfeed, a balanced and comfortable sound experience ensues. Crossfeed blends segments of the original signal from one channel and routes it to the opposite channel with a slight time difference, centering the sound image. With customizable settings like Shelf Cutoff, Shelf Gain, and Mixer Level, users can adjust the crossfeed intensity to suit their personal listening preferences.

Astell&Kern KANN Ultra DAP Music Player Review Video
PROS
Amazing flagship ES9039MPRO DAC - Low-end Extension, transparency
Larger screen, All of the standard AK Features
CONS
Larger DAP, but still portable (happy trade-off for more power)
Design
The big thing to talk about with the design is the re-design of the volume control/scroll wheel. You can now adjust it with your thumb while you hold the music player in the same hand. It doesn't sound like a big deal, but it does change the experience from every other Astell&Kern music player that I've held before. with the volume wheel adjustment perpendicular to the DAP you have to use the other hand to grasp it to adjust the volume. Being able to see the full circle of the volume adjustment on the back of the DAP is a nice touch - the CNC milling and groove work on the knob is a work of art and lovely to look at. The new standard for Astell&Kern DAPs is the LED ring around the volume knob to give you additional information on the sample rate of the music you're listening to.
On the top of the music player, you'll find four ports - a 3.5mm unbalanced and 4.4mm balanced port for pre/line-out, and the 3.5mm unbalanced and 4.4mm balanced headphone outputs. You'll also find the power button next to those. On the left-hand side of the device are three buttons - track skip backward, track skip forward, and play/pause. On the bottom of the KANN Ultra is the USB-C port for charging and USB audio out along with a single micro SD card slot for expandable external storage. On the right-hand side is the volume knob and LED ring for additional track playback information.

Testing with the KANN Ultra
For my testing setup, I paired the KANN Ultra with both the Dan Clark Stealth and Expanse with a Black Dragon Premium Cable. Both headphones are pretty hard to drive for most portable setups and needless to say the Ultra handled both with ease. There are four gain modes that we'll get into in a bit, but I had plenty of headroom for these even in the High Gain stage - note that it goes up to an Ultra gain stage above that if needed.
The KANN Ultra is equipped with the new ES9039MPRO DAC in a dual configuration. The new MPRO variant of the PRO chip includes a built-in stereo MQA renderer and eliminates the need for complicated DAC filter tuning. It's also future-proof with the ability to playback up to PCM 768 and DSD 1024. The 9039MPRO has even more advanced modulation than the existing flagship DAC to reduce power consumption, noise, and distortion for better audio performance. It would be one thing if the KANN Ultra was packing just one of these new flagship DAC chips, but it has two, and the sonic benefits from the design are nothing short of superb.
The clarity and detail of the chipset stand out with a lot of different genres, but combined with the output of the KANN Ultra and you have a DAP that can go toe-to-toe with some home systems out there. There's a weight to the sound that only a KANN DAP can produce - heft in the bottom end, never bloated-sounding - no-undefined and muddy low end, but rather impactful, precise, and lots of extension. I loved Classical and Jazz with this setup personally - with both the open and closed-back Dan Clark headphones. There is great expressiveness and nuance throughout the performances - a rich-sounding and dynamic listening experience - from the quietest parts to the most bombastic - the parts that get your adrenaline going. This combo's not just good for Classical and Jazz though - Rock, Pop, even Grunge and Metal sound great with this portable setup. You can vary up the headphones and cables for more sonic options too - headphones and cables have individual sound signatures so the options are endless based on what kind of music you like. If you want to use the KANN Ultra as a music source in your home system, we recommend connecting it to a DAC via a Silver Dragon USB Cable - since it does USB Audio out. Keep reading below to get to the Dragon Cable recommendations section where we talk more about what upgrading to a Dragon Cable can do to the sound and performance of the KANN Ultra. Bottom line is that the new flagship DAC is superb, but the real star of the show is the power. The KANN Ultra is the DAP for your hard-to-drive planar magnetics all the way.
I'll make a quick note about wireless and Bluetooth. There is some confusing among the specifications that the Ultra was only equipped with BT 4.2. It is in fact equipped with Bluetooth 5.3. Sure, it's updated, but if you're planning on using the KANN Ultra with your favorite wireless headphones then you're missing the entire point of the DAP. It's like buying a Ferrari and keeping it in your garage to look at. Put that horsepower to good use. That's what it's designed to do.

Comparisons
The largest departure here with the new model is the size of the music player itself. The Ultra upsizes the DAP from a 4.1-inch screen to a 5.5-inch. The real estate is noticeable and similarly appreciated. The larger size doesn't make the Ultra music player any less portable, because Astell&Kern always does a terrific job with keeping the shape of the DAP ergonomic and lightweight with the materials they choose. The KANN Ultra also features the latest Crimson UI/UX, a sleek and modern-looking interface with a dark and red accented design. It helps the Ultra feel new and updated compared to the older Astell&Kern front-end designs.
Dragon Cables

Verdict
The differentiator here is not just the increased output however, but the addition of the pre and line-outs. This offers the user lots more options with how they want to integrate the music player into their system, either portable, small-form desktop, or even full-blown desktop compatibility as a standalone music source. You're not limited to simply a headphone setup on the go. Options. Astell&Kern has always been stellar about giving the listener options with how and where they want to listen to their music, and for that, we thank you.
