Are manufacturer AC cables good enough?

This is akin to sitting at home with a cheese sandwich, and coming online to ask if we think you'll like it.

Since your question was regarding PS Audio I thought I'd post this email I received:

"One of the most common questions we get at PS Audio is, what cables should I buy? For years we've recommended one of our favorites, AudioQuest. Inevitably, the next question was, well, which AudioQuest cable? And we didn't have a good answer. So, I teamed up with Darren Myers and my dad, Paul, and we spent the last six months hand-curating a select series of AQ cables that sound best with each PS Audio component. The differences we heard were remarkable. And now, we can confidently tell you which cable is the perfect match.
 
We were so excited about the pairings that we decided to partner with AudioQuest and offer this curated collection directly for sale from PS Audio. You can read more about our collaboration with AudioQuest, and watch a little video we made, here www.psaudio.com/connections
 
If you'd like to know which cables are the perfect match to your PS gear, let me know. I'd love to help.
 
All my best,
Scott

Nobody is giving away great after market cables.HELLO!!

After reading many opinions on PC's here, it seems like it all boils down to two factors:

A cable needs to be of a sufficient gauge to feed your unit the required power to operate.

Then what's left?  What else can differentiate one power cord from another?  From what I ascertain, whatever its inner and outer construction is, it seems many think it is one power cords ability to filter out impurities/noise coming in from the grid.

Unlike other cables, I don't see how the delivery of electricity can act as a tone control other than the impact of the two items mentioned above.

it's not just the cable, but the connectors also...some think it's the plugs that actually make the biggest difference...
