I hear very minor or no electric noise differences. Not even when I boost
the high frequencies nearly 20 db with an equalizer. I hear different low
freq. response though. More low freq. ambience on number two + on number
three a slightly phase shifted sound as if your neighbor run water through=
his pipes.
Very interesting.
