You don't mention any of your equipment.
My first guess would be your speakers and their drivers potentially not being phase coherent especially at or around the crossover frequencies (most dynamic speaker drivers are not phase coherent to one degree or another).
Perhaps in your case, your speaker drivers lack phase coherence to a larger more obvious degree. If what you hear happens on many cd's and on another cd player.
Second guess is that it could be your cabling is producing a pretty good time-smearing effect.
Third guess would be a combination of 1 and 2.
-IMO
