I know this has been discussed before but I thought I would bring it up again to bug 2 channel people if they happen to find this thread through a Google search.
Anyway, I'm sure several of us have gotten into arguments on other forums about whether or not quad is worth it as far as adding an extra dimension to music enjoyment.
The encounters always devolve into the 2 channel people declaring things like they only have two ears and so they only need two speakers. Obviously an unthought-through and ridiculous argument.
Or that they find sounds from the back unsettling or distracting.
And there is the true difference between "them and us". They find sounds from the back unsettling. We revel in them.
