Can you hear matched power cables?


I recently read some Shunyata marketing material on the Venom 3s which posited that an audio system should have a matched set of power cables (V3s, of course). I have a couple of (really heavy) Virtual Dynamics cables, a Pangea 9, and a couple of cables delivered with the components. I'd like to upgrade those remaining generic cables, and wonder what the difference is between a mixed set and matched set of cables. I can't really hear any difference when I switch my current fat cables around.

The question becomes, is it worth replacing the Virtual Dynamics and generic cables with Pangeas, or replacing all cables with V3s, or just get a couple of either the Pangeas or V3s to replace the generic cables?

I'd be interested in hearing your experiences with this. Of course, my ears will tell the story, and some companies will let a buyer return a cable, so tell me what you discovered.

I would say that you need to match a power cord and particular component. As for the total system match...well maybe too but it will take a lot of time and effort.
Just put Purist Audio Limited on transport, dac , phono and preamp; and Dominus ferox on power amps and be happy forever. A bit expensive though.
This Pangea hype is getting on my nerves; I got to try it, I guess.
Iv'e had the best results using all Shunyada Anaconda's and Pythons , keeping power cords the same length helps . To get the most out of there cords you need to use Shuyada's power conditioners too . As far as upgrading , if you have good cords now , the bang for the buck factor will be low and likely not worth it , unless you have a very resolving system .
Replacing all my PCs with ZU Mothers a few years ago presented a cohesive improvement in my system that I have not even thought about changing. (Though I have changed a few of the items they are attached to. If I could just figure out how to stop that.)
For Inna: the Pangea are really for the person who wants something besides a stock cord. They are very, very good for the price. But i would not say they are for folks who have expensive cords and wonder what all the hype is over Pangea. Some of those people might like Pangea, but the real target is the cheapskate buyer (like ME) who wants a really good sounding powercord dirt cheap.
So for all you tightwads out there: go buy a Pangea while they are still on sale!! The retail price has been inching up gradually, so the sooner you get one, the cheaper it will be.
And be grateful to Pangea even if you hate them for becoming famous overnight, because of Pangea's low prices, many other manufacturers have introduced low priced cords!
I have piles of Pangea so I am set for life...
Elizabeth, try Custom Power Cord original Top Gun on preamp and phono. They show up here for sale from time to time. Though quite expensive when new, you can get them for $120-$150 for 5ft now. Then maybe you will want to get rid of your piles of Pangeas.
