Astell&Kern KANN ULTRA

Fueling Your Sound
The KANN series is adored by audiophiles all over the world for its performance that focuses on ultra-high output and clear sound.
KANN ULTRA, the 5th product in the KANN series, continues the success of the KANN series by providing the highest output of any Astell&Kern player, the inclusion of Triple Output Sound, and an optimized processor and UI/UX to make it even easier to enjoy clear sound performance.

With four Gain Modes that provides up to 16Vrms of desktop Hi-Fi level output and sound, and ES9039MPRO Dual DAC chips, KANN ULTRA perfectly powers many of today's headphones with high resolution. A separate Pre/Line Out allow users to enjoy the sound with a variety of different devices.

Triple Output, Triple Sound
KANN ULTRA features a Triple Output Mode that allows you to enjoy Astell&Kern's perfectly prepared sound when connected to demanding headphones, highly detailed IEMs, and external devices.
Instead of simply separating the output ports, Astell&Kern's Teraton Alpha technology allows for separate amplifier/sound design for the Headphone Out and Line/Pre-Out ports to provide the optimal sound for each port.
Complete your powerful Head-Fi system even on portable devices with the KANN ULTRA with Triple Output.

4 Gain Levels And Outputs Up to 16Vrms for The Perfect Head-Fi
To run the most sophisticated IEMs and headphones, a DAP needs to be able to fully deliver an output that matches the characteristics of the receiver.

KANN ULTRA features 4 preset gain settings up to 16Vrms, the most powerful output of any Astell&Kern player,
to optimally run the many IEMs and headphones available today.
The current-handling capability of the output port has been increased to reliably run devices of different impedances at the gain Level setting,
and the AMPs have been separated into Balanced and Unbalanced to optimize currents and reduce noise for the best possible sound.

On top of providing the most powerful output, KANN ULTRA features a larger
5.5-inch screen and improved grip compared to KANN CUBE, which was popular
for its high output versatility. Weight of the KANN ULTRA has been significantly reduced to 390 grams.

TERATON ALPHA, The Essence of A&K Audio Technologies
From an ultra-high output that can run even the most delicate headphones, to the Triple Output design, and the complex amplifier design with minimal noise in a compact portable audio player, this would all not have been possible without AK's Ultimate Sound Solution, TERATON ALPHA. Astell&Kern has taken the TERATON ALPHA to the next level with its know-how in noise reduction at ultra-high power, acquired from its predecessors such as the KANN MAX and the CA1000 series.

TERATON ALPHA, engineered through continuous research, is Astell&Kern's unique technology that has been designed to produce audio playback that is as close to the original sound through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface.

Upgraded Sound, the Newest ESS Flagship DAC
The KANN ULTRA is designed with dual ES9039MPRO DACs, the newest flagship DAC from ESS, to deliver richer and more expansive sounds that exceed your expectations.

The ES9039MPRO is an updated ES9039PRO model that has a built-in stereo hardware MQA renderer. It has even more advanced modulation than the existing flagship DAC to reduce power consumption, noise and distortions inside the DAC for enhanced audio performance.

Astell&Kern has redesigned the AMP BLOCK to ensure that the clear, high-resolution sound of the ES9039MPRO is clearly expressed through every port of the Triple Output, and each output's characteristics show its own advanced performance.

Incredible User Experience with Next-Generation Octa-Core Processors
KANN ULTRA is the first to feature the next-gen Octa-Core processors with significant performance improvements, allowing you to enjoy KANN ULTRA's incredible sound performance with faster system speeds and a 4th generation UI/UX that flows faster and smoother.

The audio circuit area is physically separated from the processor area, which includes the CPU, memory, and wireless communication components, and is equipped with a dedicated shield can to minimize the heat and noise generated by the processor.

Crimson User Interface, A Music-Only Player
KANN ULTRA features a Crimson-themed UI/UX for the first time in the KANN series, making it a "Player for Music" that leaves an impression
in the process and experience of listening to music.

The Crimson UX/UI is designed so that users can quickly browse music categories and re-discover songs within their music library.
We also added an easy album art search function so that users can re-discover the joy of viewing and interacting with music album art whilst listening to their music.

The crimson theme focuses on edge, simplicity, and dark mode keywords.
The color theme of black with red highlights lowers visual fatigue and offers intuitive user experiences, and includes many other improvements
to the device’s user-friendliness of streaming app services, artist view, album sorting, and album art search function.

Immerse yourself in music with Crimson UX/UI.
