I wouldn't think the 250ohm would work at all. My Cowon iAudio 9, Fuze, and Touch are all sufficient to run the 80ohm version, but benefit from a a cheap amp like the PA2V2; however, I use them straight out of Cowon or iPod on walks every day happily.
That being said, most people I seem to meet are deaf (including, concerningly, some head-fi members) , and can't hear anything unless their skull is vibrating.
