iRiver Astell and Kern AK100 Review


Sometimes to fight a giant, you have to think small. Just ask iriver. When the South Korea-based audio company created its portable, high-resolution music player, the Astell and Kern AK 100, it had no intention of taking on industry titans like Apple...

Stunning sound quality ; Extensive file versatility ; Premium grade components

Slightly sluggish UI ; Some quirks in function ; Expensive

If premium sound is your guiding priority, and you have the cash, this digital music player may be worth taking a chance on, quirks and all - just don’t expect it to behave like a new iPhone.

Iriver Astell & Kern AK100


Iriver's Astell & Kern AK100 ($699 direct) is a portable media player with the chops to surpass not just CDs in audio quality, but SACD and DVD-Audio as well—thanks to its support for 24-bit, 192kHz lossless FLAC and uncompressed WAV files. The thing...

Incredible audio quality with the right material

Extremely expensive. No AAC or Apple Lossless support. Buggy. Mastering-quality files are expensive, take up a lot of storage space, and aren't widely available. No headphones or AC adapter included

Audiophiles with the means should take a close look at the Iriver Astell & Kern AK100, a high-end media player that delivers exceptional sound quality with the right music files, but it comes with plenty of compromises.

Astell & Kern AK100 Portable Music Player Reviewed


An audiophile quality portable music player has been desired by many. Now, that player may have arrived in the Astell & Kern AK100 portable music player. Steven Stone investigates in this review.

The AK-100 delivers superlative sound quality in a small form factor ; The AK-100 has support for full-resolution 44.1, as well as 88.1, 96, 176.2, and 192 kHz files ; The AK-100 is compatible with a wide variety of headphones and in-ear monitors ; The...

The AK100 does not come with any software for the Mac, but the Mac OS is supported for basic drag and drop functions ; The AK100's 20-ohm output impedance could present mismatch issues with some extremely low-impedance, high-sensitivity earphones

Obviously, not everyone needs high-resolution capabilities in a portable music player. But if you do want to be able to take full-resolution uncompressed music wherever you go, the AK100 delivers. While its ergonomics may not be as slick as an Apple...

Disclaimer: iRiver supplied the demo unit for this review.Everybody is talking about the new Astell & Kern from iRiver. I don't know who came up with the branding...

Positive feelings building, I proceeded to give my friend Sem the Momentum for him to listen to his AK100. His comment was “Good, but still lacking dynamics.” I was pretty surprised, but he was right. Even with a relatively easy to drive Momentum, the...

Astell & Kern AK100 review


The Astell & Kern AK100 is an audiophile-grade personal music player, but is it worth the salty price tag? T3 went in for a closer look

Portability ; Practicality ; Hi-fi bothering sound

Clunky interface ; Awkward touchscreen

If you're used to a great hi-fi at home, you'll always be disappointed by the nagging compromise of lesser quality sounds on the go, even through good headphones. The AK100 initially seems like an expensive solution, but practical at the same time.

iRiver Astell and Kern AK100


Once you start using this, you will never, ever want to listen to your I-Pod again. Even lossy, compressed files encoded in AAC and MP3 sound stunning.
