The Cowon players are famed for their DAC chip and that they are able to drive some of the larger headphones out there. So for general use a portable headphone amp truly is not required.
That said, I own a Fiio E7 amp/DAC that I used in the office to ensure the Mac would deliver good sound and to up the power for the poor input on the car stereo.
So, I have one... but on Cowon players I've never needed one.
