At this moment in my system....listening through my amp and speakers has the best Sq Although my grado 325's and rega ear mk2 are good,they don't really come close to the smoothness in treble and sheer excitement within the xs and pmc's.I guess I would have to spend a few bob on a headphone amp and maybe another level or two up in the grado range . it's the first time I've had my amp and speaker set up sounding better than headphones.you have to go along way up the ladder to better a pair of decent Grado cans in speaker terms.
I for one feel you cannot compare the two. You cannot discuss sound without talking about the room system is in and it's obvious effects. Most people if you are perfectly honest have their system set up in a far from ideal room situation so it could, theoretically, perform much better. Headphones negate this room effect and so to all intents and purposes, sound better. Providing the headphones are of a good quality there is much less 'interference' to that sound.
I use headphones regularly both at home and on the move. The major difference, with my current two headphones is the lack of 'atmosphere' and in particular, soundstage. I don't believe you can get this unless you have a really good pair of open-backed headphones. I will be looking at some planar magnetic types soon and may sell all of my current headphones to pay for them if they give me this requirement.
