The USB connection and iPhone5S iFI Audio nano iDSD! High-resolution playback on iPhone finally complete!

Koyama-san, a customer who made a YouTube video of the nano iDSD and how it connects to the iPhone. We enjoyed the video very much. Even though our Japanese is a little rusty, we understood the instructions and advice.

Yoroshiku Koyama-san!
