@westcoastaudiophile sorry if I misunderstood your question. Yes, I can absolutely tell the difference within each of the upgrades with my current system. I would say not so much with my original McIntosh system with the Zu Audio speakers. That system didn’t have the dynamics to hear the benefit of upgraded cabling.
My current system is very revealing and has a ton of dynamics. Adding different power cables can add "color" for good or bad. Its not unlike upgrading speakers, a 6" woofer is not just a 6" woofer, there are nuances in the way its constructed and the material that is used. Same for the power cables in my experience.
