Can Levinson 512 be directly connected to a headphone ?

Hi Al
Your answer and instruction are great, very very helpful !
More and more l intend to have a  project that I should use a formal highend headphone amp to get rid of those electronic things that must be taken into consideration.
By the way, in your first reply, you mentioned "   You would also have to provide a means of adapting the headphone’s plug to the player’s two RCA outputs, of course." If not that kind of simple cable shown by the link you gave above, what pattern of adapting apparatus (  some kind of adapter ? special cable ? or even an adapting box......) can be used?
Could you also suggest a link to know?

Thank you again !

Assuming the headphones have a standard 1/4 inch plug the adapter shown at the following link would be suitable, as it is designed for two-channel applications:
