Astell & Kern AK70

The Astell & Kern AK70 is a small and lightweight portable FLAC player that lets you listen to high-resolution audio anytime, anywhere. Inside its rugged aluminium body, you will find the most advanced components and technology currently available. To take care of the faithful, naturally colourful sound, a single Cirrus Logic CS4398 D/A converter is used. This allows the AK70 to play back 24bit 192kHz signals into bit-to-bit type. 

Key features

  • The Cirrus Logic CS4398 converter supports 192 kHz / 24-bit audio
  • Supports 32-bit signal
  • DSD 64/128 can be played back through conversion to PCM
  • Digital input for use as an external DAC with a computer
  • Wide range of wireless streaming possibilities through the AK Connect application
  • Internal memory of 64GB + Micro SD of up to 128GB
  • Aluminium body in mint colour
  • Digital output USB-OTG (USB Audio)
     

Top audio quality in a portable device

The AK70 can be used as an external sound card by connecting with a PC/Mac through the USB port. That eliminates all the problems that can occur when you want to play back DSD data with a standard embedded sound card. In the case of using the AK70 as a USB DAC, it can support up to 24-bit 96 kHz bit to bit, providing much richer sound through superior ambience and resolution way beyond the limits of an embedded sound card.
