Reading the wide variety of opinion on this topic (nothing new there, then
) I found myself wondering, before I do anything about it:
Does the benefit depend on your location? for example, I suspect the mains will be "cleaner" in a detached house on a spacious plot compared to a semi or terrace or flat where there is far more potential interference nearby. Surely this will affect the level of "improvement" or otherwise.
how about a straw poll among the fans and the detractors?
