Need help determining next upgrade - 3rd ATTEMPT

Hello, my third attempt in 3 days to get this thread started. My system sounds a little smeared when playing complex musical passages, I'd like to have more detail and separation. Consider the sound of a full orchestra or even the crescendos in the works of Explosions in the Sky. I blame either the pre-amp or amp for this. Seeking suggestions for upgrades in these areas.
Pre-amp: Halo P5, McCormack RLD-1, ??? (must have remote)
amp: Parasound A-21, Odyssey Stratos, ???
Check out my system link and let me know what you think.
