As I seem to have caught the headphone bug I want to add a set of these to my burgeoning collection but can't decide which version to get. I will listen to them mainly from my hi fi which is more than capable of driving them so my gut feel is to get the 250 ohm version. However there may be occasions when I will use them from my iMac or iPod classic and wonder whether they will struggle with these?
I have invested in a Fiio E5 and wonder whether I should get the 80 or the 250. Advice welcome please.
