There is an interesting book called "The Wood Effect" (sorry, but I've forgotten the author). This is a rather detailed book that cites many studies and tech papers (with lots of footnotes) regarding 180 degree phase inversion. According to this book, as well as my own observations, by switching phase (reversing BOTH speaker terminal wire connections or using a phase inversion switch, if available, on your preamp), you will get a noticeable change in sound reproduction on most source material! These changes include: wider soundstage, and better soundstage pinpointing of vocals and instruments.
Phase Inversion
recently read about a cary slp98 pre amp as well as a few others that are phase inverting. also read that this can be reversed by changing the polarity of the speaker wires. my question, why do manufacturers do this? does it make an audible difference? why reverse it? i also have read about cd's that are recorded phase reversed. what is the point of all this. thanks alot.
