Was it a couple of centimetres short?An Audioquest power cable has just been measured over at the other place,I was absolutely shocked by the results.

Full Morgana here. Heard a definite (very positive) difference between them and the Naim originals and the Teddy Burndy’s. Have swapped them in and out to confirm. No blind testing though, so could be all in my head.
I draw the line at power cables. Complete foo. I can’t tell the difference between an Amazon basics kettle lead and a Naim power line. Had the power line for a month, swapped it for a kettle lead, not a blind bit of difference to my ears.
When you drop them?Different cables sound different so it might be part of the explanation but other factors will apply.
Most things are a compromise between cost and performance so improvements are possible.

Yes I get that the current draw in fact goes in pulses, but what reason is there to suppose that ordinary mains cables are not specfied to permit the peak current draw during the charging cycle rather than just the rms. This property is the same for all power supplies, not just ones for audio devices. Is it being suggested that any of this is news?
If this has an effect on the output of the psu then it should be trivially easy to demontrate it using measurements. And I have no idea what you mean by "most folk" but I'm quite confident that anyone who designs PSUs knows about the current draw requirement of an AC/DC converter.I am sorry to say you have not got the point or the idea, so thick is good but pointless to exceed 3-5 time the rating, but as you and other are aware current in thick cable taken at high speed can be effect by wire gauge i.e.skin effect.
Most folk assume 50Hz/60Hz is all it needs, this is true for electric fire ,lamps etc But a device that has rectification and can demand current to charge fast the caps and the skin effect can make a small difference, now I and other have found this can be heard
/start soapboxOh dear, didn’t take long for this to go south, did it?!
Perhaps he would rather stick needles in his eyes?Perhaps Colin could send one of his cables to Amir over at ASR for measurement?

Because measurements let your ears know how it will perform! Will you ever get off your negative high horse over cables.How much are they, perhaps I will buy one and have it sent over, I would like to see some actual measurements rather than conjecture.
Keith
Why would you bother? Some of your customers frequent this forum, myself included. Do you think your reputation is enhanced by actions such as this one? Do any of the cable 'haters' / objectivists shop with you? Does Amir shop with you? I bet the answer is no and no.How much are they, perhaps I will buy one and have it sent over, I would like to see some actual measurements rather than conjecture.

Fully agree and have posted similar opinions, it must put new/newish members off posting cos it’s obvious it’ll turn into an argument.Why would you bother?

I'll be frank, I find the constant attacks against anyone who says anything positive about cable upgrades both irritating, juvenile and off-putting. You are far from the only one and most of the others are on my ignore list - doubtless they don't care.
Tony has complained that the negativity on cable threads take up far too much moderation time and effort. It hasn't stopped any of you. There is complete lack of respect for both the moderation team and fellow forum members with differing opinions. You are all so busy being 'right' that a little consideration, a little space for those who see the world differently to you is seemingly impossible.

Have you approached NICE incidentally because the mind boggles at the number of lives you could save if you could perusde them to use your cables on MRI, ultraound scanners etc. Or Jodrell Bank?
Sorry Jodrell Bank uses wave guide on there dishes as the frequency is far to high for cable and the losses would be to high, due to skin effect.
As to the medical equipment using Ultra Scan etc they do use Litz, just have a chat with my cousin at Oxford Instruments.
As to PSU designs, I have designed power supplies from a few watts to 5.5MW DC, and some very high speed resonant full bridge SMPSU for a space station that run at a clocking frequency of 1MHz and a 1KW with a 97% eff rating, not a simple 9V battery job.
As to folk, for me that a term I use between stranger and friend, not as a insult to anybody.
Yes. Given the overwhelming body of scientific evidence and the compelling moral case it defies belief that anyone questions the utility of aftermarket mains cables. When will governments act? With so many legislators in the pocket of the generic mains cable industry, not soon.Iagain I'm amazed at how many continue to deny Climate Crisis.
