Including shipping to UK the FiiO is about the same number in $ as Amazon want in £, about 100 but I haven't looked at the DT880. I know the FiiO is very well thought of. Cheers, Dave.
BTW is there a special way of adding links to posts or is the problem that the above link is so long? EDIT the link turned out better in the actual post than it looked in my original so ignore the 'BTW' above .
