Our Ultimate Holiday Wish List: Astell & Kern AK70

While most of the world has moved on to streaming services such as Spotify, those who value high-resolution playback still cling to portable music players, and the high-end South Korean brand Astell & Kern is still improving them. The Android-based, Wi-Fi-compatible AK70 supports hi-res files like AIFF, FLAC, and WAV, in a reasonably light (4.7-ounce) package. You can control volume with either the hardware button or the player’s 3.3-inch LCD touch screen.
