Do you mean it sounds better on an different physical (other monitor) or software-internally Output? Maybe you just need to get a better transparency in your Mix. Seperate the Frequencies of the Kick Drum accuratly and then Cut off all the Frequencies, which disturb the Kick´s spectrum or try to get in a Side-Chaining Compressor, or look what Phase Inversion on the Kick Drum does.
You actually even got the Option to export and create two different Mixdowns, One is made by the first Output, and the other by a Second.
