Sorry, no one say power cord = antenna. Please don't point to another direction.
There are many compliances in different countries and they own their specific standards.
I think there are many electric appliances are compromised the U.S. standard, EN/IEC61000-3-2 since the power rating over 75W(RMS). Of course, many Bristish standards are also needed to be followed.

What's the improvement by adding the "240VAC Main Filter"?
Would you provide the data to proof the result before and after?

Everyone want to get the Clean Power especial for the case of the HiFi-Mad. But they cannot prevent noise when they power on a electric drill.

I don't want to challenge everyone or your idea but I suspect the practical improvement?!

如果各位家中電器全都符合EN/IEC61000-3-2的話,全部無需濾波器.
通常濾波器 ...

I only did this post because it did improve the sound of the speakers for me..... It was not intented to be a item to rock the world... hence there is no "proof" in terms of your standard.

Why not try and make one yourself and tell us how you think about it? I suppose you can provide much more technical details/ proof whether it work or not....
