i am a bedroom producer and today i heared my tracks played on a souround sound home cinema stereo. The setup was low budget but it gave me back an eye-opening result. If i played a conventional retail CD the sound quality was very good (as usual).
Then after i played my tracks on this cinema setup.

They lacked lots of top end compared to teh retial tracks and were overall less dynamic. This is my first encounter of this kind and has made me want a reason why this is.
Is it down to mastering or production?

If my production is as good as i can get it, and i use a fairly decent home setup here, will the mastering process make it more polished? or do i have to rethink my producion/mixing technique to come up with a nice balanced sound?

thanks in advance.
