I am not a moderator, just someone who read your post and can kinda see possibly what's haapening.
Are you referring that when you have made your track, it only sounds good through your headphones. Then after you have readied the track for recording and played it through a stereo it didn't sound the same?
If that where the case, how are you mastering your tracks?
Does every track have it's own reverb, EQ settings point in the stereo field?
Has it been Parametric EQ'd as well?
Have you compressed/compiled/EQ'd all the individual tracks to sound how you want them.
The reason I ask is that if you don't take the time with all of this, everything will sound like a mash of sounds, in one stereos band field.
If you want any help on mastering, just hit me up on my profile.
