I was considering buying a Fiio X5 as well as this but recently there have been posts less than flattering about it's SQ and UI. It seems that the X5 SQ may have been over hyped and there are now some balancing and differing experiences being expressed.(or maybe those reporting poor SQ have cloth in their ears. They certainly seem to be Apple Fanboys).
Apple ipod and mp3 have ruined many people's ears... amen.
