I've always wondered this
But why has no other company stepped up to make LODs? I know LODs for iPods are fading out due to lightning, but two years ago even. There was no real easy way to get a cheap and decent quality LOD for Apple devices besides FiiO. Unless you lived in HK or another tech developed region of China, or even more unlikely, to have a very very techie and audio friend who could make one. You were basically left with only FiiO LODs as the only real choice of an international seller.
Just bewildered a bit really
Maybe no one wanted to make cables for a specific target audience or obtaining a quality 30-pin dock connector was somewhat expensive? Companies like Toxic Cables make cables for headphones or regular interconnect cables, but not the iPod LOD in particular.
