Good for you Carl.
I trust you'll hear the importance of what good AC cords can bring to the table. When you experience that, remember this that I'll share with you: First, cables are not a "tweak" as it appears you suggest. A tweak (or an accessory) is something your system can perform with or without. Equipment is stuff that your system needs in order to function. Cables are equipment. In context of that, I've firmly come to the conclusion that good AC cords are foundational to a music system. Before any other partnering cabling, they can begin to show what a given music system is capable of.
Sound crazy? Yea, I suppose so. We expect to be emotionally impacted by out system's playback. Not so much intellectually stimulated by understanding all the whys of performance. Like going to a good concert - You come away with "Man...that was Good!" Not "Boy...that was Right!" Easy enough to understand to some degree why S/Cs or I/Cs might contribute to our emotional experience without becoming an EE. Simple as they may seem, AC cords a another story. It doesn't as readily make sense that a power cord can do wonders for a system. They need to be looked at differently than S/Cs or I/Cs. Understandably, many enthusiasts don't care to know all the intellectual reasons why an AC cord can allow a system to operate more efficiently. After a ragged day at work, most of us just want to settle down with maybe a good glass of wine and be emotionally nurtured with some good music. Not come home and do more work by testing dielectrics for capacitors, write the charts of our music collection or study wire theories. We really don't care so much if we can grasp all the workings of our music system. It's more about "Is this thing making music magical to me?". Add power cords as an important means to get there.
You might get a kick out of this: Some years ago, I dismissed the importance of power cords. Hell, almost twenty years ago I dismissed wire period. Today, I place AC cords at the top of cable or system hierarchy. That's quite a turn about. As it goes on these boards sometimes, I can hear it - Perhaps one would say of cable manufacturers (us included) "Well duh!, you make yer bucks from sellin' cables. You gotta promote AC cords." That's not true - take AC cords out of a product line and, if you're good at what you do, you'd still have a business that's worth the effort and that makes a good difference for folks. I would also counter by saying that many passionate high end manufacturers produce products out of what they themselves use. Not what can I make to turn a buck. They trust their "creation" would be of value to others and offer it in the market place. The market bears whether there's any value of one's efforts and the buck takes care of itself. Win/Win for everyone.
Anyway, I hope there's a bit of insight for you here. Let us know what you find when you get to auditioning some power cords. Might be useful for others.
Cheers!
