When mixing, many elements tend to fight for centre.
In most cases EQ can help make space however this may only take you so far.
Try panning your elements towards the left or right and you may find that you use less processing to hep elements have their own space in the mix.
This works especially well with mid to top range mono sounds which have a simular tone, such as two hi hats.
You should get great results: just watch out for tipping the tonal balance too far one side.
