20 amp cables for PS Audio P20?

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.
