A good headphone amp should only help, not hurt.
Glad to hear they sound good as is though as well.
I have Sennheiser Momentum over-ear phones. THese are designed to work better with portable devices than the audiophile Sennheiser models like HD650, and sound wonderful of an Ipod TOuch, for example, but I think even these can benefit from a good amp with a bit more juice than most common portable devices can deliver.
