Subject: Please explain bi-wiring and after market power cords for home audio...

My previous question on speaker wire was answered by:  Bruno Putzeys Staff, 
Electrpacoustics and Analog Electronics, Philips ITCL.  This is another 
audio question where scientific evidence is lacking.  These two techniques 
I asked about should be fairly easy to de-bunk.  It is claimed that high 
end power cords improve audio sound as does the technique of bi-wiring.  As 
an engineering grad I can find nothing to support this.
