IRIVER Astell&Kern KANN Portable Music Player

Description

THE EVOLUTION CONTINUES
Astell&Kern’s KANN provides a new power standard for mobile music performance. Combining a high-quality audio player and a high-performance amplifier, KANN draws on the technological expertise of Astell&Kern, the leading Portable Hi-Fi Audio manufacturer.

TRULY POWERFUL, HIGH-QUALITY OUTPUT
Astell&Kern has introduced a new product design that cleverly incorporates a high-performance amplifier into a player for a perfect merger of two independent devices. Supporting the output of 7Vrms when connected via high-gain balanced output, the KANN not only drives high-impedance headphones without an additional amplifier, but also reliably reproduces high-quality sound with low-impedance speakers.
