The Astell&Kern AK100 MQS Portable Player Trumps Pono
The Astell&Kern is the ultimate portable high-fidelity audio system capable of studio mastering quality sound (MQS). Feel the phenomenal realism of music though 24bit/192kHz high-resolution, lossless Mastering Quality Sound (MQS) that cannot be heard on a CD.
When compared to CDs, the music files used during the mastering process in studios (24bit/192kHz) contains 6.5 times more information and results in a more original, precise and enhanced sound.
If things were only always just like that picture....There are other like-devices out there including the HiFiMAN HM-801 player ($790 w/32GB SDHC card) that can handle up to 24/96 files but the Astell&Kern MQS Portable Player has raised the bar with its 192kHz capability.
