Get 200hrs of signal thru the new cables then re-evaluate. Sometimes the difference is more apparent when you go from best to worst and you realize what you’re missing.
Also, few additional items to consider-
1. bad room acoustics will mask differences between cables and even between components. Any reflective surfaces like tiled floors, windows on the side of the speakers…anything that will cause the sound to bounce or create slap echo will impact what you are able to hear.
2. speaker placement and listening chair position relative to speakers - if not properly setup it will negatively impact your system performance and will most likely negate any gains possible with cable upgrades.
