Robert Morein keeps ducking:

"The sound of a QSC amp evokes the piquant saying "You can't **** on my
back
and call it rain." "

Why won't you answer the question? Have you ever done a bias
controlled, level matched, comparison of any QSC USA amp against any
other amp?

I believe we all know the answer is that you have never done any kind
of bias controlled comparison ever.

IOW you are ****ing on our backs and calling it rain.
