Turn the power cord upside down.

post #1 of 24
Thread Starter 
A person I know have always claimed that the stereo sounds better when the power cord is connected a certain way. I was at first sceptic but we tried listening with the power cord connected first one way and then unplugged it and put it in the wall upside down.

It actually sounded better one way than the other!
It's not a night and day difference but it feels a little more natural when connected right.

Has anyone tried this?

That's awesome!

Sometimes I would listen with my power cords not even plugged in. It sounded very nice. I liked the sound so much that I padded my walls and unplugged all of my electronics. Now they work much better.

I installed linux on my powercord.

It's possible if your equipment in non-polarized.

Over here, most outlets are now polarized, though.

You can easily unpolarize cords with a dremel. Which doesn't hurt anything, since polarization is irrelevant for AC current.

Doesn't hurt anything, but can compromise the safety of the device.

If you are referring to cables that have a figure-8 connector at the equipment end, yes it can be plugged in either way even if the wall socket end has a plug with an earth pin so it only goes in the socket one way.

Switching around of the figure-8 is supposed to affect the rfi that the transformer can generate (according to the direction of the winding if I recall correctly). You can measure this with a meter - I've tried it myself on my home cinema setup trying to get rid of a annoying hum. Though I can't say whether it made any sound/picture difference the meter did buzz more when the lead was reversed.

I can see why you're making fun of me but if this would be such a strange thing then what about all the people claiming their cables sound better after being used for a while (burn in). We don't think them as crasy.
Any by the way read this article it explains this in detail. http://www.gcaudio.com/resources/howtos/acpolarity.html

And for the record our power connectors here in Sweden are symmetrically made so they can be turned upside down (be put in the wall either way).

I should say that the equipment that was used was not high-end at all. Just my parents B&O tv set with external B&O speakers.

It might not hurt the equipment, but it can kill the operator, especially in the case of some older equipment. I'd hardly say it's irrelevant.

That's quite a big issue, hehe.

Which way is up and which down? Why is Australia at the bottom? Is it at the top? My head hurts...
