These two DACs differ mostly in their applications. The K3 is designed for desktop use. It has no internal battery, so it will need to be powered from your computer. The Q1, on the other hand, is ideally designed for on the go use with your mobile device. (Although it does has a line-out for an amplifier or active speakers) The Q1 comes with a micro-USB to lightning adapter for your iPhone or a micro-USB to USB cable for your computer or Android device. The K3 uses a USB-C to USB cable, which is designed to be hooked up to your computer.
