Now, if I delay my left speaker by say 14 times "x" millisecond

I have virtually shifted both speakers 14 meters further away?


The sounds will arrive at the same time as if you shifted both speakers
14 meters which is not the same thing because it's not changing the
ratio of direct to reverberant sound or distance to boundaries as if
you physically moved the speakers.

Such time delays are only going to be relevant if you're trying
to synchronize with pictures. People are much less tolerant of
sound arriving before pictures than they are pictures before
sound which happens in nature as you move farther from the
speaker.

This also means that delays of that magnitude are useful when you have
video processing (notably conversion between interlaced and progressive)
that's delaying the picture.
