The problem is with a conflict of all of your low end elements. At that "instant" on the first beat of your drop. You have (I'm assuming) Kick, sidechained bass, "sub drop/downlifter", and other assorted downshifters (while even though they might be white noise they still have a ton of low end energy).

Some tips:
Put a very small fade in on the first kick beat. It will allow the transients of your impacts and downshifters to come through on that first beat. This is done by a lot of prog producers including Jay Hardway, Volt and state, Manse etc...

High pass the white noise downshifters to get the low end out of their samples out of the way.

Make sure your Sub and bass are sidechained hard enough so that they are not conflicting with the kick.

Add a sidechain/lfotool/volumeshaper to your downshifters.
