Astell&Kern is the ultimate high-end portable audio system, capable of reproducing Master Quality Sound (MQS). Music files in MQS format (24bit/192Khz) contain over 6.5 times more music information than a standard CD with 16bit/44.1Khz. This results in the outstanding super accurate and true to original sound, which is in no way inferior to the original studio recording. We call this Master Quality Sound (MQS). Equipped with two Cirrus Logic CS4398 DAC converters (per channel), it opens up a new world of music listening.
