The Abso!ute Sound Review by Allan Taffel

With the Astell & Kern AK100 Digital Audio Player you will feel the phenomenal realism of Mastering Quality Sound (MQS) or high-definition lossless music through 24bit/192 kHz sound processing that cannot be heard through a standard CD.

What is MQS (Mastering Quality Sound)?

When comparing MQS to Compact Discs, the MQS music files used during the mastering process in recording studios (24bit/192kHz) contains 6.5 times more information than a CD and results in a more original, precise, and enhanced sound.  Data is extracted 192,000 times per second.

The AK100 by Astell & Kern Meets the 5 criteria of Hi-Fi Audio

The Astell&Kern MQS (Mastering Quality Sound) Portable System meets the demanding criteria of Hi-Fi audio even from its small size and portability.

THD + Noise (Distortion): The lower the THD + Noise signal rate, less distortion is heard. The Astell&Kern achieves a 0.0009% distortion signal rate.

SNR (Signal to Noise Ratio): As the signal-to-noise ratio increases, the clearer the sound becomes. The Astell&Kern signal-to-noise specification is 110dB

CROSSTALK: The higher the number in the crosstalk specification, the higher the isolation in the L/R channels develops. The Astell&Kern has a crosstalk specification of -120dB.

Frequency Response: The frequency response specification of +0.02 to -0.02 in the Astell&Kern provides a clear degree of sound volume from Bass to Treble.

Jitter: With smaller figures representing irregular tremors of the signal waveform, the better the device the soundperforms performance. The Astell&Kern has a Jitter specification of 90PS. 

The AK100 is Equipped with the Wolfson 8740 DAC.  The Wolfson is the world’s highest performing 24bit/192kHz stereo DAC

The Astell & Kern is the world’s first portable device equipped with the Wolfson WM8740 DAC. Consumers familiar with LINN, ARCAM, and other high-end audio equipment (AV Receivers) should be familiar with the Wolfson WM8740 high-performance 24bit/192kHz Stereo DAC. With the world’s highest level of signal-to-noise ratio (SNR) and the lowest level of harmonic distortion (THD) performance, the WM8740 has the reputation in the UK of producing the richest and warmest sound impressions.

Utilizing With the integrated WM8740 DAC, the signal to noise ratio of 110dB found in the Astell&Kern greatly significantly improves sound quality.

External Optical DACs!  The Astell & Kern can be used in combination with or act as an external DAC via the Optical In/Out function.
