Astell&Kern is the ultimate digital music source that brings you Mastering Quality Sound or MQS. Astell means ‘Stars’ in Latin and Kern means ‘Center’ in German. We believe Astell&Kern is the centre of music.
Original music performances recently have been captured in digital almost exactly as they were performed due to new and advanced recording technologies currently available. These great-sounding recordings are mainly listened to in inferior sound formats, such as MP3 or streaming services. With the debut of the MP3 format, music lovers scarified the quality of the sound for the convenience of being able to carry their music collection wherever they went. Because MP3 heavily compresses the original file for the sake of convenience, you only hear inferior vocals and instruments, and the full soundstage and ambience from the original recordings is missing. The movement of the original performance often disappears when listening to compressed MP3 music. Astell&Kern is the solution to the poor quality of musical sound for the sake of portability, and the way to ultimately bring back the original sound quality of the music, MQS, back to music artists, recording engineers and professionals.
Astell&Kern's pursuit is to provide the natural and original sound without distortion. It offers almost the exact presence with tiny details you wouldn’t have noticed from other music systems by playing back high-resolution music bit for bit, exactly as it was recorded. The exact sound without missing any bit of the live performance in recordings is what Astell&Kern is known for.
The AK70's DAC, based on market-proven CS4398 chips of Cirrus Logic, has been used for years in Hi-Fi audios and the second-generation Astell&Kern devices.
The AK70 Hi-Fi music player sports a 3.3" TFT LCD display, which gives high-quality WVGA (480 x 800) resolution. A lustrous mint colour aluminium casing makes it look eye-catching and also offers complete durability. A big volume control round-shaped button facilitates ease of operations.
AK70 has been provided with a 2.5 mm 4-pole balanced output (2.3 Vrms). This arrangement rules out any disturbances occurring in signals/inverting amplifier signals. The music player not only delivers sound-rich music but also increases output because of its double transmitting signals. The AK70 can be used with a variety of balanced earphones and headphones made for Astell&Kern. It can also support the 3.5-mm 3-pole unbalanced output (2.3 Vrms), with compatibility with a variety of Hi-Fi earphones and headphones.
The AK70 supports USB audio digital out, a first among Astell&Kern devices.
The Astell & Kern AK70 is compatible for use with a range of balanced earphones as well as Hi-Fi earphones and headphones from Astell & Kern. Equipped with a market-proven Cirrus Logic CS4398 single DAC chip, it supports 24-bit/192kHz Bit to Bit Decoding. AK70 also supports USB Micro-B input for charging and data transfer, apart from MTP connectivity.
You can connect diverse digital-input portable amps through USB to the AK70. The AK70 can transfer DSD in native through DoP. It can also convert DSD into PCM for output for portable amps that do not support DoP.
The AK70 can be used with a USB DAC that can double as an embedded sound card by connecting with a PC/Mac through the USB port. In the case of using the PC's embedded sound card, one may have to go through a complicated process to play back DSD data. In contrast, the AK70 can do so simply by connecting with the PC.
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.
The AK70 can allow users to rip CDs with ease by linking with the AK CD-RIPPER. By inheriting from the AK500N, it supports the CD track error correction feature and the meta data (ID3TAG) auto input feature using Gracenote's database without any change.
The AK70 comes equipped with the AK Connect feature that can be connected with network-ready Astell&Kern devices.
It is also appointed with wireless networking DLNA (Ver. 1.0), which makes it easy to work with NAS/PC on the same network and through an AK Connect app supporting smartphone/tablet computer.
