Upgraded cords for linear power supplies?

I've got a a Keces 12vDC linear power supply feeding my DAC and streamer, and a Swagman Labs 24vAC unit powering my Rega TT-PSU. Is there any reason to use upgraded power cords (Furutech plugs, DH Labs cable) with these? Doesn't all the magic happen in the linear power supply?

Just wondering....

I'm sorry to bring this up again, but if the spec of your power supply is an AC output, it is NOT a linear power supply, even it the (Swagman) box it is in is labeled as such.
Why do you say this isn't a linear power supply? It looks like it has a standard toroidal transformer and LC RFI filtering. While it doesn't convert to DC, I think this would still be considered a linear power supply.

I use an upgraded cord on my Teddy Pardo LPS feeding my DAC and it is noticeably better over a computer grade power cord. WyWires Silver Juice II Digital Series. Not sure the difference over the Standard or Digital Series but guessing additional shielding... with Furutech plugs.

I can hear a difference between different PC's into a Swagman LPS. Not as significant as aftermarket cables into an audio component.

Very simple. If it is specified to have an AC output it is by definition, not a linear power supply (which would imply a DC output).Second, in the description Swagman says it is a toroidal transformer with some EMI filtering. Unfortunately they put in the same box they use for other LPS.

What is a Linear Power Supply? ... 
A linear power supply typically uses a large transformer to drop voltage from an AC line to a much lower AC voltage, and then uses a series of rectifier circuitry and filtering process to produce a very clean DC voltage. 
The Rega TT is powered by AC, so this Swagman unit is simply an external power supply. It would be superior to an onboard PS due to the toroidal transformer, better caps, plus isolation.
