For trivial cost and virtually no effort, consider Machina Dynamica "Flying Saucers for unused AC outlets." Also, there is a companion version for window glass in the listening room (and, beyond).
These items outdid the benefits of power conditioners in my listening rooms, and allowed to be heard a quiet, clear and detailed sound similar to what can be heard in systems off the grid on battery power. There is no impairment of dynamics since nothing is within the AC power path. Appreciation of micro and macro dynamics is actually enhanced.
Then go right ahead with the planned dedicated line project and listen for any further improvement.
