Getting out of portable audio. Astell & Kern original AK120 with its dual mono Wolfson DAC design. Comes with the leather case in good shape and USB cable. Battery life is still very good. Makes a great portable DAP or digital source/transport with its optical output as well as wireless Bluetooth connectivity. From a smoke free home. Expensive bugger at its original $1299 price.
Has version 1.42 installed. Out of transparency, the USB DAC functionality only works with USB 2.0 ports, not USB 3.0. This is a limitation with the firmware and only applies if one wishes to use the AK120 as a USB DAC. The player itself is in very good condition with any surface scratches only on the film covers.
