The NAD amp has a good phone out - you will be in heaven with a good phones. I like to have a few and switch them around depending on mood.
Above 2 recomendations are good - think about these too.
Koss ksc50 ($16 at amazon) Light and comfortable (portable as well)
Upper koss models
I like the crisp metallic quality of Koss - not found with the above 2 fine phones. Good to have both - soft and crisp.
