Investigation and dismissal of 'special' mains cable used as an RF Filter

post #1 of 3
Thread Starter 

Interesting article debunking some more audiophile cable mythology ....

 

'Can a mains cable be used as a ‘filter’ to block the entry of Radio Frequency Interference (RFI) into domestic audio equipment from the mains?'

 

By Dr Jim Lesurf, School of Physics & Astronomy,
 St Andrews University.

 

'Are some fancy forms of cable generally better at doing this? Some recent papers[1][2][3] have been published that present measurements on some mains cables. These consider some specific cables which – it has been claimed – may offer better RFI rejection than ordinary mains cables. The idea being that the specific way the cables are constructed does provide higher RFI rejection. The contents of the papers has been said to provide a ‘scientific’ basis for the claims about the specific cables. I’ve been curious about this topic for some years, so I decided to investigate and see what I conclusions I could reach...'

Interesting, but all these audiophile words are confuzzling

Just read the general conclusion (point 6). :)

 

To put it simple: spend your money elsewhere.
