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.

If digital, you can currently pick up a Pangea audio ac14 se or ac14 power cord for your DAC depending on the one currently in use, for well under $100. Using a power cord like this designed for digital source applications can probably only help and not hurt.

I am noticing improvements similar to what you seek since applying the ac14se with my mhdt Constantine DAC. I did the upgrade needing to replace an existing damaged power cord and knowing that I have greatly improved performance of my setup in the past by systematically shielding against EM noise.
Thanks all. The power upgrade is something I want to do. but first, the room treatments.
Try some 12 gauge solid core house wiring on the speakers. All those little strands smear the signal.
