Should All Power Cables be Alike?


It has entered my limited consciousness that there lies the need to change ALL power cords if you change one; but I don't know the answer. For example, would upgrading only the AC power cord to a power conditioner or generator be limited improvement if the components feeding into the power unit weren't also upgraded? Another words, if changing only the primary AC cable (i.e., the one from the AC wall plug) is one sub-optimizing improvement without also changing the AC cord from all the components in the system?

So, you recommend using a 10 or 12 gauge AC power cord - I assume that translates into a 20 AMP AC cord from the AC wall outlet to the power center? I have 20 AMP AC wire to my circuit breaker.

The circuit breaker and dedicated line are rated 20 amps. Your PS Audio is 15 amps, so the wall receptacle would be a grounded 15 amp type. A 20 amp receptacle has different connectors.

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.

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.
