I popped into Alans house last night whilst he was doing these experiments with the spectrum analyser and it was quite interesting to see how much RFI is actually present within the room, I guess that all rooms would be similar? What effect this RFI has upon the sound is way above my electrical knowledge of putting a 3 pin plug on but Im interested all the same.
If by reducing the amount of RFI present within the room does have a desired effect on the sound then this will be something that I will definitely be looking at myself
