The Powerhouse

The Alpha is the third in our acclaimed ‘Kann’ range of players - and it’s the most powerful, the most portable, the best sounding and - let’s not pretend otherwise - the best-looking Kann yet.

KANN Alpha

The power to entertain

Despite being the most compact Kann player yet, the Alpha has huge reserves of power. With an ultra-high 12Vrms output constantly on tap, it’s able to drive any headphone or IEM to significant levels without breaking sweat. Which means it’s the most adaptable digital audio player around.

Balancing act

Kann Alpha is our first player to feature a 4.4mm balanced output alongside its 2.5mm balanced and 3.5mm unbalanced sockets. This level of flexibility, along with Apha’s sky-high power output, leaves you free to use your favourite headphones secure in the knowledge that Kann Alpha is maximising their potential.

Perfect isolation

There’s no point in offering a choice of balanced lines if they share the same circuitry - that’s a recipe for noise interference and performance degradation. So we’ve completely separated the 2.5mm and 4.4mm balanced outputs using micro relays, switching off circuitry that’s not in use and preventing noise interference.

Incredible wireless performance

To maximise your wireless listening experience, Kann Alpha is our first player to feature aptX HD Bluetooth 5.0 - range of connectivity, speed of transmission and battery life all benefit. Plus, of course, aptX HD allows wireless transmission of high resolution 24-bit digital files, for perfect A&K sound without wires.

The highest resolution

Kann Alpha features dual DACs - the class-leading ES9068ES by ESS. Which means it’s able to handle 32-bit/384kHz and DSD256 audio files without compression or loss, so you can be sure that you’re hearing everything the artist, the producer and the recording engineer intended.
