Should All Power Cables be Alike?

I ownhigh end power cords ! End to end would encompass the world!! Cardas 1000.00 Clear  to Shunyata to Wireworld platinum power, and the beat goes on! Can power cords change sonic capabilities of electronics! Yes, they can! Is the incremental improvement worth the money! NO, it's not! 
Before you bear fangs and head for my throat, my statement is in my opinion! I have just short of 100k invested in a high end audio system! .Power cables won't change modest priced equipment into mega high end audio 

@lowrider57 good point, I missed that. 20 amp power cords have different connectors at the component end and will not fit on components with 15 amp IEC inlets. Most components have 15 amp IECs. The plug and connector ratings apply mostly to which IEC and outlet they'll work with. The current handling rating mostly comes into play when taking the gauge of the conductor into account. So a 12 or 10 gauge power cable could safely carry 20 amps of current. But you don't want to get a cord with 20 amp connectors because it won't fit into the back of your amp..

Wilmars - Firstly - I agree with the posts above
- all cables make a difference
- power cables are no different.
- all stock power cables should be replaced
- even to the power conditioner

DIY solutions I have found to be very cost effective (i.e. most bang for the buck)...
- MRI grade outlets from Take Five Audio
- Sonar Quest Silver plated copper mains/IEC connectors from Ebay
- DH Labs Power Plus bulk cable.
- KLE Innovations RCA plugs

I’ve tried high grade stuff from Furutech, but the above seemed to work just as well for a fraction of the cost.

If you are serious about DIY take a look at...

These are the best cables i have built - better than some esoteric brands I have tried costing thousands of dollars.

That’s right, Todd. And I meant to say 20 amp "cables" have different connectors.
Also, the 20A line and breaker is for the total current draw of all components. The PS Audio P10 combined with the amp into the wall would not exceed 20 amps.

toddverrone - my house was destroyed in the 1989 earthquake in Santa Cruz, CA. I rebuilt and had a dedicated 20amp line placed in the walls where I planned to place my system. The contractor put 15amp AC outlets on the 20amp wire ... thus my questions about putting in 20amp AC outlets. My amp is an ARC REF 75SE ... 20 amps, I believe. It's taken me a long time to recover my stereo equipment - earthquakes have a way of doing that to your personal possessions. So, now I'm upgrading cables and the AC outlets feeding my system.
