The purpose of the discussion is to dispell the common myth that you need to
buy a "high end" amplifier for good sound.

I understand all that, and I'm not saying you're wrong (in fact, I've agreed
with you). I'm simply saying that there's no convincing some people, even when
you have truth on your side. Will is obviously unwilling to make the leap from
perception to reality, and realizing that would end the debate and the waste of
bandwidth.
