do you mean like this?
which complains the m50 has a small soundstage.
however... from the EXACT same forum.. (on a "what is a soundstage" question)
let me quote you a part:
I think we have a winner:

Even though you can explain to someone what soundstage is, everyone has their own take. And lets face it, with headphones, you've usually got 2 drivers to work with. Sorry, but you aren't going to be able to give any up/down or in/out cues with just the properties of the headphones, you can do left/right because you have left & right drivers. Any other spatial cues are from the recording, and describing them (i.e., describing the recording) usually ends up being pretty subjective.
hmmm... not so consistant advice from the same place right? it all boils down to one thing: sound is a VERY subjective thing and just because one person is completely blown away by what they say is good sound from one device someone else might say it sounds worse than a $20 pair of earbuds. perhaps not quite that bad... but you get the point. often when dealing with sound a few generalizations can be made however those are still only what the majority of people seem to think about a given topic. remember, the majority isnt always right (hence why gamers buy $50 mousepads, $100 mice, and special gaming headsets).
for instance, i've actually played games... and while i wouldnt call myself an audiophile at all but i'm somewhat concerned about decent sound. considering that at home i have a pretty expensive surround sound set which sounds very good... when i say that i had no issue with the headphones i really meant that. perhaps they do sound like they have a small soundstage.. however this can be taken in a positive manner as well: they are very immersive. again, as i said sound is very subjective and thats my own opinion. when i played games it did not affect my playstyle in any way for others it may differ.
now i'm not saying that there isnt some shred of truth to what they are saying (there is) however the difference isnt as clear as black&white or good&bad and its also not purely statistical (it has lots of opinion in what they say as well). another reason i highly suggest trying out headphones at a local store first if possible.
honestly the best thing would be if you could test out the headphones to see what you personally thought about them. some places like guitar center may have a bunch of headphones in stock where you can make such tests to see what you personally thought. after all its your ears not ours that matter and its your opinion not ours or anyone elses which matters. you might hate both the m50s and the beyerdynamics, you might love them both, you might like one and hate the other. honestly its hard to say.
i only mentioned the m50s as a suggestion since i personally enjoy them and they are a great price. i only defend them since so many people hate on a product just because it doesnt conform to their one way of thinking about things. you are free to pick whatever headphones you like based on whoevers recommendations that you like (though i highly suggest trying them out if at all possible) and i even encourage you to look at other products and do quite a bit of research to find out what might work for you best. if you go for beyerdyamics? great. if you go for grado? great. pick something which fits your own needs.
as far as a soundcard is concerned..
if you have pc speakers as well as headphones then a nice xonar 5.1 card which has virtual surround as an option would be a good choice.
sorry for the wall of text, i just wanted to make a point of saying that just because "everyone" believes a certain thing that doesnt make it true and also that sound is a very subjective thing. just because many people like something doesnt mean that others do.
a good example of this is how everyone raves about the m50s being great sounding (even some on that forum) however they are quick to judge it at other times.
i think most of the people on that site are audiophiles who are very picky, very narrow in what they consider good and tend to state opinion as if it was hard proven fact.
when dealing with opinion on sound you need to take it with a 10 pound grain of salt (treat it skeptically)
hopefully this is at least being helpful.
