Hi my original point was really about misinformation about the tonal qualities was being dripped into the thread in a rather deliberate way over a few weeks. Comments which were picked up and perpetrated. To my veiw point what was being said made no sense in engineering terms and so the original information was not being countered properly I'm naturally sorry if, as some sugested I've given offence. I'm pleased to say we Brits don't take offence very easily. So I guess we are more apt to annoy those perhaps with more sensitive natures.
