Per usual what we mostly get is the forum egotists who have a little knowledge so think they are experts. So they seize on statements and articles as justification without understanding the basics or the parameters / context of the information.
So we have people like Muccus singing the praises of earth bars and earth mats without realising why, or why it should improve *HIS* system, and then applying his solution as universal, "I am right" "I am the greatest" type of forum behaviour.
A good earth has two reasons 1/ to provide a safety path for wayward dangerous high voltage currents in a *non isolated* *non insulated* system, 2/ and as a cure all for stray signal currents like hum loops. Well the problem is, as with all cures it has side effects, and if you don't have the illness then you don't need the cure, and in fact applying the cure can make you ill if you don't need it
So two reasons for the earth, one to do with the mains and one to do with the signal. As I keep saying to everyone and hopefully some are listening now, there are different construction methods for electrical appliances and as to how they use (or not) a ground path (earth). I have published this link many times before and eventually it may sink in
http://en.wikipedia.org/wiki/Appliance_classes So for those with enough intelligence to read they will see only those appliances built to Class I *may* need all this bollocks. Build to Class II and you can largely forget about it.
So how many of you understand a floating earth (or more to the point 0v ref) I doubt many do especially the big forum egos. Or how Class II avoids so many of the problems that are created by mains supply. This is why the BMU has proved so effective musically as it is built to Class II.
Anyway it is a big and complex subject and per usual it is best left to people who do understand it to discuss it, and everyone else just listen to the music and decide what is best for them, BUT take all Muccus type mains bullshit advice with an enormous pinch of salt.
