Astell & Kern KANN ALPHA High-Resolution Portable Audio Player
Astell & Kern KANN ALPHA Overview
Providing you with audiophile-quality sound in a compact and portable form factor, the KANN ALPHA High-Resolution Portable Audio Player from Astell & Kern sports up to 12 Vrms power output while delivering up to 14.5 hours of continuous playback. Audio is kept clean and pure with a 2.5mm and 4.4mm output, which use micro relays to keep them physically separated. For improved quality and durability, the 4.4mm output has a gold PVD coating to minimize noise. Two 3.5mm outputs (one for headphones and one for optical audio) are also present. A -141dB crosstalk measurement (at High gain) helps to ensure an extremely minimal amount of leakage between channels. Even electronic noise has been suppressed, with ultra-small tantalum power capacitors.
To help match the full depth of original audio recordings, the KANN ALPHA has been given dual ESS ES9068AS DACs. The sound can be further customized with the selection of one of three DAC filters: linear phase fast roll-off, minimum phase slow roll-off, and a hybrid fast roll-off. If you choose to stream your audio to an (optional) Bluetooth-compatible headset, quality is maintained with support for 24-bit aptX HD and LDAC codecs.
When playing back your favorite audio, you can navigate through your library and adjust settings via the KANN ALPHA's built-in 4.1" 720p touchscreen. In additional to a digital interface, the KANN ALPHA DAP provides a physical scroll wheel with a multi-color LED to indicate volume level and track bitrate. The LED gives you visual indication on both the current volume level and the bitrate of the track that is currently being played. You can store your audio library on 64GB of built-in storage, which can be expanded via an (optional) microSD card up to 1TB in size.
