thanks to the heads-up by ck, we discovered that many UK-made power cords which are attached with US-plug (export models, as demanded by some audiophiles in countries like malaysia) have negligently configured the pins in the UK fashion, meaning that the manufacturer didn't not reverse the Live and Neutral pins!

the problem is indeed a very serious one. audiophiles in malaysia use a mixture of UK and US plug and generally they are confused about the L and N pin configuration. even local electricians don't know the difference.

it also shows that british power cords manufacturer pay scant regard to US plug configuration, eventho' they export their power cords with US plug connected.

this results in wrong polarity, which causes poor imaging, focus, transparency and the overall tonality would suffer.

readers, please be careful the next time you buy a power cord. make sure you use the multimeter to check the polarity.

Hats off to you Maggielurva!!!

Polarity is one of the most important aspect {and often neglected} of Hi-fi set up...You do not get it right, you would be washing thousands of dollars down the drain ........

Gentlemen...This Maggielurva, he knows hi-fi.Yes,Polarity ,polarity,polarity can't stress enought how important it is. Ever wonder why something people are wondering about certain electronics and you don't seem to enjoy it??Check the polarity.

for those who are wondering what it is all about here is a start;

The polarity is also an issue if you were to use the US plugs on the UK receptacles..

The only sure way is to check
Instant Circuit Tester..or use the multimeter[just be sure you know how]

Which means if an adaptor was used it would be correct. Maybe that was the idea?
So which brand of cables are these or are they nobrand which would also provide another explanation.

I think it was meant to be used with ther adaptor{which is not a good idea!!!!] The easieast thing to dpo is to reverse the polarity at the receptacles [only if you use all of the same British made cables}

The point is ,.we audiophiles should trust no one...

anonymous and kurien,

why do you need an adaptor when it is already with US plug?

anyway, only novices use adapter. there are no-no for high-end audiophiles.
