Hi leiter, I am in direct contact with a cozoy representative and he managed to give me a set of replacement cable, I asked whether I could purchase another set of cables but he said the lightning to micro usb cables are in very limited stock right now, he told me they are working on new products due for release next year, he hinted at another dac even smaller than the astrapi and also stated that they are working on an upgrade cable which will be shorter and more durable than the current ones, he did not mention anything about buying the cables a-la carte though. I saw a micro usb to lightning pin multi-media adapter a few days ago on a website but can't remember where I saw it, might want to try looking up on it, hope it works for you
