Does any of your electronic components make any sense "electrically"? IMHO the high-end does not make any sense electrically - we pay very expensively for distortions and noise that please our preference. Power cables are not different from other components. We know they sound different in our systems. Just because we can't correlate what we listen with measurements does not imply they do not carry electrically benefits. Shunyata people have written a nice and interesting technical white paper on the reasons why power cables affect sound quality - have you read it?
Most things - almost all of them - do not make any electrical sense in our hobby. Tubes, for example, are an electrical nonsense!
BTW1, all my power cables are certified. Nordost, Transparent and Audioquest, to refer just to three known brands are all certified, otherwise they would not enter the CE market.
BTW2, what are the "electrical benefits" of audio signal cables?
I don’t think a paper written by a company making power cords is any level of evidence at all, funny you would even suggest that as an explanation
yes people prefer certain types of distortion I agree, but that’s also measurable
it’s good in Europe that they are certified by CE
i am not talking about preference of correlation, I am talking about it having no measurable effect at all
if you like a 300b yes you like the distortion profile, but I can also see that, and go ok that’s what it produces and you like it
with power cords it’s not really the same
we don’t listen to AC, the average home has 2-3% distortion at the wall, so you place you 2 metres of power cable after the 20 metres in your building, and given its high quality it conducts that 3% distortion beautifully to your audio device
but all that nasty distortion, is then converted to DC by you devices power supply , no more distortion
audiophiles are enamred to good power supplies, for obvious reasons
the majority of noise and distortion that predominant from any device is self induced eg the 300b amplifier , and has nothing to do with the power cord which can have no real impact in a well designed power supply , which most audiophiles would strive to buy
when I plug an expensive power cord into an competently designed audio device, we see nothing significant happen in noise or distortion profile or frequency response so there can be no preference as I say it doesn’t make any sense
