Hello, emergingsoul
If you can get a "Niagra quality" power management center and appropriate power cables installed in your system for evaluation, I would do so.
I would suggest, however, that you either a) wear some Depends, or b) have an extra change of underwear close by. I do not want to be responsible for what happens when everything in your system with a power cord sounds remarkably better -- all at the same time.
Or, you may hear no difference at all. But, I'm leaning more towards jaw dropping.
