Mains Lead £1870!!!!!

[Darth Vader]

There is another reason for expensive and posh looking cables, fuses etc and that is to show off.

Years ago I heard an interview over the radio with an uber rich character that had inherited huge wealth and never worked in his life. At one stage he was asked why he had his watch customised with over £50K of precious stones as these didn't make it a better watch for timekeeping. His reply was something along the lines " you can say you have a rolla parked outside but I can show I am rich by wearing one on my wrist - if you've got it then flaunt it"

This expensive HiFi bling makes no discernible difference but added to the rest of their uber expensive kit they can boast about the high cost and their pride in being stinkingly rich.

Cheers,

??? The mains cable will be carrying 50Hz and odd harmonics up to about 1kHz. The current will be modulated by the average audio volume. If the psu is a switcher with power factor correction, the harmonics will be at a low level

He wrote current. With a rectifier power supply the current in the cable will be sharp, short, tall spikes with a repetition rate of 100Hz.

How many people wear their hifi about their person?
I can understand an arse wearing something flash in a highly visible way to flaunt wealth, but cables?
The idea that people buy expensive hifi to show off has never been convincing to me. The watch may be more visible than the Roller, but theRoller is much more visible than any hifi.

Even if you paid top barristers £600 per hour to build them they would still be a very profitable item at £1870.
Unless the barrister was all fingers and thumbs.

Werner, Steven was referring to the tolerance specs for AC supplied by the national grid in the UK.

My original question:

Dears Sirs,

I am thinking of buying a Furutech Powerflux Mains Cable.

Before I make the final decision I would be interested to know a bit more about the technology of the cable.

The specification states that the copper wire is treated with Furutech’s Alpha Cryogenic and Demagnetizing process.

Can you explain how you discovered magnetism in copper cable was a problem, and how you go about permanently demagnetizing it?

Thank you

Kind Regards

Mike

And Furutech's reply:

Dear Mike,

Thank you for your interest in Furutech products.

Furutech engineers believe that demagnetizing the ferrous impurities that can exist in high grade copper - even if the impurities are minute - performance in audio applications can be improved.

Furutech uses a large ring demagnetizer on all metal used in their products.

What do we make of that then?

The worrying part, especially coming from engineers, is the word believe. Imagine a bridge building engineer saying "we believe it's strong enough to cope with high winds".

 

[Joddle]

More worrying is that their "belief" only accounts for the bit of wire that they supply - what about all the rest of the copper cable stretching between the power gerneration and the outlet socket and the copper in the kit itself - I suppose all that doesn't count!!!!

 

[Tigerjones]

In the absence of proof all you essentially have is belief.

balance of probability works as well, it's what get's me on an airplane. So if I'm the first person to buy a cable then that's a risk, but if it's a popular cable then the risk is less.

I think that's what a bridge building engineer would say, it's the bridge design engineer that does all the calculations.

Excellent stuff from candycable.

I've been (occasionally) saying this for a long time:- mains filters are bad, screened mains cables are either bad or have no benefit and everything is capacitively coupled to everything else by parasitics etc etc. The result being that every time you change the interconnects and mains wiring you are changing the way the parasitics interact. The thing to focus on is clean grounding. The materials used in the cabling are far less important than the topology and impedances. It's just engineering (but maybe not 1st order basic textbook stuff).

I doubt I could have put it anywhere near as well as candycable though.

Yes, good to get some info from someone who faces these issues in a commercial situation.

Sorry, business morals.

Apologies for my lack of knowledge concerning engineers involved in the design and build of bridges. It's not my specialist subject.

 

[FireMoon]

No however, I'm told he did remove one her nipples and replaced it with one made from a composite material and then shortened her left leg by 2 inches as apparently it cuts out RFI when she's sitting in the listening room at the same time. Russ swears blind he's run tests with identical twins and there is a noticeable improvement with these mods.

You've really not been paying attention to the life-and-death/risk assessment elements to this discussion.

 

[Tigerjones]

No. It's irrelevant.

Nobody falls off a bridge swapping a mains cable.
