Do I need higher quality power cords?

If you like the Isotek, and I'm guessing you do, why not more of their cords?  And buying used is a great way to go tons of used power cords on here all the time.

Alright - clearly I'm a little biased, but here goes:
First, ensure that you can separate "high quality/caliber" from "expensive" - they are not one and the same. ;)
Second, no matter how much care you take in the selection and/or use of dedicated outlets, line conditioner(s), voltage regulators, or anything related to power (the "power chain"), it's all for nothing without a quality PC to your gear (the last link in the chain).
Speaking of the "power chain", for those of you who argue that you are limited by said chain, so nothing you do at the end of it matters, I'll say this - while you may not be able to strengthen a chain by adding a link at the end, you can certainly weaken it.
To put it another way, good tires will not get you more horsepower, but lower quality tires will transfer less power to the road.
I agree with the poster who said the PC to your conditioner is the least important, so here's a simple experiment (forgive me if this has already been mentioned) - swap the Elite PC with one of your stock cords and see what's what.
Cheers and good luck!

To clarify, I mean that if you have a stock cord running from the Orion to your amp (for example), use that cord from the wall to the Orion, and use the Elite PC from the Orion to your amp.

Good idea.  I’ll try that.

So anyone wants to answer my question from above?

I have 14 AWG running inside the wall. I have a Torus plugged into it with a short 14 AWG cable. If I use short 14 AWG power cables for everything, how am I being limited in power, especially for low power gear.

Sure I get that the power cable is stranded whereas the power line is solid in the wall, but there is no way these components are being restricted in power by extra 6 feet of power cable of the same gauge, even if stranded.
