i've recently got a pair of Philips Fidelio headphones and whilst they sound great through my Sony SACD player which has a dedicated headphone amp, the sound through my iphone left me underwhelmed. Now I've read on various forums that the iphone5 is not the best music player, so I looked at getting a relatively cheap portable dac/ amp like the fiio EO7 or E17. The problem is there appears to be no way of feeding the fiio a digital signal from the iphone5. There is a old 30 pin connection type lead available for the iphone4 but not the 5.
I'm assuming I can only use the amp section of the fiio when connecting to the iphone?
