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.

Another speaker placement method. Keep in mind all these methods are starting points. Quarter inch incremental adjustments can make significant changes at the listening position

Equipment changes before speaker placement tuning is not recommended.
I agree with Al thet the "room treatment" or "speaker positioning" remedy can be easily tested by listening to the offending recordings while sitting closer to your speakers..."nearfield" as they say.
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.
