Astell & Kern AK Jr

This (much) cheaper version of the AK240 might not have stylish carbon fibre on its back, but it does have a lovely-looking aluminium shell. It’s also extremely light at 93g and just 7mm at its thinnest point. Like the AK240, this 64GB player can be used as a USB DAC, while there’s Bluetooth streaming and DSD support.
