Wish I had put more emphasis on cables earlier

It is possible to have an unexciting result, especially if you are cheap about it, i.e. choose an inexpensive 14 AWG power cord. Put enough money into it to get a nice result. Try for at least 12 AWG, and buy two, not one. Changing two is almost always easily heard.  

I take it you're just a BIT resistant to advice on cables? How long do you want to take to figure out power cords?  Five years? Ten years before you try?  :(
EVERY power cord is critical!

isochronism, perhaps you should carry that PC with you in a sachel. You never know when you’ll need it! ;) Me? I'm ready to die; no problem.  :)
