20 amp cables for PS Audio P20?

A 20 amp power cord has a different termination than the 15 amp version.
You would probably have to use adaptors to be able to use a 20 amp cord- though they wouldn't be expensive, it would seem to negate the purpose of using a 20 amp cord to begin with.
IMHO, just buy a good 15 amp power cord and be done with it. The new Audioquest Thunder, Tornado, Hurricane cables are my pick.

Ok thanks. Still not clear about one thing. Of the P20 is a power regenerator why does it even matter what cable I use whether an Audioquest Hurricane or a Radio Shack one?  
It’s converting to DC and then generating a totally new sine wave. So no matter what comes in it shouldn’t affect the output sine wave. Right?

Power cables do make a difference on the Power Regenerators; they’re essentially a power amp and have a power supply… they make a difference and I’d recommend using a large shielded power cable with dedicated circuits to get the best out of your P20.

I have had several components IEC converted to 20amp because many cable IECs do not fit tight. Other than that a heavy gauge cord is essential to handle the current

Example, I have  Kaloric Air Fry oven; the connected PC gets really warm when using it at 400*s+ for > 10 minutes 

I’m not sure if a 20A cable will sound different just because it is a 20A cable, but the P20 will provide more power and probably sound a little better when fed with a 20A cable from a 20A circuit.  If you only have a 15A circuit no point in the 20A cable.  Having said that, I would strongly recommend running a 20A dedicated line with 10 Gage wire for the P20.  That will give the best performance out of the P20.

Sir, you’re fine with the power cable that you have.

If the PS20 has a 20 amp IEC than use a 20 amp cord, if not use the 15 amp cord.  Don’t make it harder than it needs to be. I would use at minimum a 10 gauge cord. 

The P20 has the ability to be fed either by a 15A cord or a 20A cord, properly terminated. There are two AC inputs on the back. Only one can be used at a time. When used with a 15A cord the maximum power the P20 is able to manage is limited by the 15A circuit feeding it.
