Thank you gentlemen, looks like I will stick with my kettle lead for the time being.
Just one more question gold plating, is it done for sonic reasons or just to stop oxidation.
As I am shure I read some where copper is a better conductor than gold.
Cheers

Can't give you the technicalities but oxidisation is one key issue. Silver tends to be used as a superior plug contact on some of the better plugs.

Oi, Richard, get a chemistry book mate! Wink

'Cos it seems to me you're being misled, and in the process it's misleading everybody else. Cry

Silver and copper are the number one and two most conductive metals, but as both are chemically reactive, they are poor contact materials. They oxidise and tarnish.

This is why the mainstream uses gold - because it's just about inert (for the want of a better word) and only the most dangerous chemicals are able to "attack it" - like cyanide! Nuke

Gold also has the ability to stave off electrolytic corrosion between it and any other metal, so a tin-plated connector can be mated with a gold plated connector and no corrosion forms between.

However, gold isn't as conductive as silver or copper, and is soft so gets worn down easily. Therefore for military, medical and computer uses, they alloy gold with copper, and that makes it 1. more conductive, and 2. much harder.

And that gold just happens to be 9 carat, and not the 18-24 carat hi-fi customers think is best... (not) Sleepy

That none should be able to park up and enjoy the view without a smartphone and the knowledge in how to use apps

You are correct I did only achieve a grade E Chemistry O'level!!!! 
I did say I wasn't commenting on the technicalities  (i.e. not on oxidisation) but merely from a contact (and indeed) conductivity vs gold.
 
By my own observations my gold does inded appear more resistant to tarnishing etc from my gold plated contacts on my Furutech Mains plugs.
 
Always good to hear the techniacl side though one good thing about silver at least it matches my hair!!
 
Big smile

Beryllium Copper. Silver, Gold & Rhodium are just so last season. Tongue

EDIT: more seriously I have been using Audio Asylum leads. Belden 19364 fully shielded copper, with a Wattgate 320i & MK toughplug, £65 assembled. Cheaper as a DIY kit. They are at least as good as my Reference Powerkords which I bought for abt £240 each about 10 years ago, when I had money to burn.

People Sometimes Like Cold Meals At Zoos In Thailand Leaving Curious Strong Gorillas Puzzled.

I think that's what I used many years ago to remember some of the Reactivity Series.

Potassium
Sodium
Lithium
Calcium
Magnesium
Aluminium
Zinc
Iron
Tin
Lead
Copper
Silver
Gold
Platinum

(I think this is what I was supposed to recall, in descending order of chemical reactivity)

Hi I used to own a Reference powekord whilst good believe their performance can be bettered quite easily and to me they are or were well over priced. On a scale of 0-10 vs my current power leads I would score the above a 4 or 5? Furutech provide a much tighter plug fit whether iec or 13A three pin.
