Astell&Kern never stops innovating. Their product lineup is always expanding and improving. So needless to say the recent announcement of the latest KANN iteration was a welcomed surprise. You're probably asking yourself, "So what's the difference?" Well, let's get into it.
Introducing KANN Alpha Music Player, the latest DAP by Astell&Kern
Pre-Orders Start 9/21/20: Delivery 10/31/20
The Wrath of KANN
The KANN Alpha is the third music player in the KANN series of DAPs by Astell&Kern. The goal of the KANN line has always been to provide ultra high power output to drive any headphone or IEM. Like the previous KANN Cube, the Alpha maintains the title of powerhouse, offering the same power specs as the previous model. Other features of the new KAAN Alpha include the following:
- The first Astell&Kern DAP to feature a 4.4mm balanced output
- Complete separation of balanced lines to provide noise-free output
- Crosstalk of 141dB and top-notch audio performance through a complete circuit redesign
- Powerful 12Vrms ultra-high output support
- 14 1/2 hours of continous playback
- Equipped with the latest version of Bluetooth, Bluetooth 5.0
- Artistic design and ultra-precision metal shaping technology that Astell&Kern has perfected
The First DAP with a 4.4mm Balanced Output Port
The newly introduced feature of the 4.4mm balanced output port is exciting, however, the most important part is how Astell&Kern implements it. Unlike other manufacturer's products, the KANN Alpha has physically separated the 2.5mm and 4.4mm outputs using micro relays. With other manufacturers, when 2.5mm and 4.4mm structures are connected to the mute circuit, noise interference is not prevented because each signal is not properly blocked.
KANN Alpha boasts noise-free output because Astell&Kern built in an independent structure that completely blocks interference from outputs that are not being used and to be switched off, therefore preventing the noise from occurring.
Gold PVD Coating Method
In order to minimize contact noise from the output, a gold PVD coating method is applied to the headphone connector instead of the typical rings used by other products. This improves both design and function.
By adopting NDICS' Pentaconn 4.4mm connector, KANN Alpha not only satisfies the requests of users, but the implementation boasts excellent quality and durability.
The Highest Level of Channel Separation
KANN Alpha boasts excellent performance measurement for crosstalk. Channel crosstalk is how much signal leaking there is between the left and right channels. The higher the crosstalk number, the better the separation between channels and the deeper and wider the sense of space that can be felt. As evident with the newly developed audio circuit design, KANN Alpha features a never-before-seen Crosstalk measurement of -141dB (High Gain), which is unmatched by any other portable audio product in its class.
KANN Alpha Channel Circuit Design
In a sense, the KANN Alpha is a mini-KANN Cube, providing the same amount of power but with longer battery life.
Same Power, More Battery
The KANN Alpha supports the same powerful 12Vrms output as the existing KANN Cube, however the player has been optimized to be more compact. This is achieved through the miniaturization of numerous parts such as resistors and capacitors, by rearranging various components and through circuit optimization. This resulted in the modification of more than 60 parts during the development process. Ultra-small tantalum capacitors, which were developed exclusively for Astell&Kern through a collaboration with Matsuo Electric in Japan to meet the high performance requirements, supply stable power to the player, and suppress electrical noise.
The redesigned power circuit used in the KANN Alpha can allow for up to 14 1/2 hours of continuous playback.
Wireless Upgrades
The Alpha is the first Astell&Kern music player to implement Bluetooth 5.0. This latest version provides great sound quality with the convenience of wireless playback to headphones and IEMs. Bluetooth 5.0 features faster transmission speed and greater range compared to Bluetooth 4.2, therefore providing a more stable wireless connection. Both LDAC and Qualcomm aptX HD is supported to provide audiophiles with the best wireless sound possible. The high-quality sound that Astell&Kern is known for can now be heard when using Bluetooth earphones, headphones, and speakers.

Customize Your Sound
With the KANN Alpha, you can enjoy the fun of creating your own customized sound by selecting among various DAC filters provided by the DAC manufacturer.
This was a popular feature which started with the SE200 music player, and we are certainly glad to see it roll over into new models. More control means that you have the ability to listen to the music the way you want.
Color Coding
Another carry-over from the SE200 music player is the color wheel around the volume knob. The Alpha features the this LED wheel which displays various playback information, including volume level and bit-rate of the track currently playing. This LED can also be turned off if desired.
