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....

No. The real magic happens in the ultralinear power supplies. Just be sure to use a UL power cord.
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.
i use single ended triode power supplies
Tube rectification is totally the way to go!

Often wondered about this. People claim it improves performance of a Rega 24 vAC motor. Mine causes hum if it gets too near the Rega power supply.

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.

Do you concur?


Not exactly. The definition of an LPS is correct.  A higher current capacity transformer has a chance to provide better speed stability to a TT. I'm not sure why you think it has any caps at all, or what purpose they would have in an AC supply, and I personally think it a bit of a stretch to call a transformer in a box a power supply.For some enlightenment on transformers you might want to watch "pints with Ayre" on utube.
