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.

Atagi,
Consider 'phase inversion' as 'nature of the beast' or 'less is more'. Electricial engineers have always had this quandry when designing audio equipment. Most have added the additional phase to 'bring' the positive and negative 'back' so people are not confused. By doing this another circuit is added, creating another potential undeseriable noise source. Conrad-Johnson equipment is non phase inverting, requiring you to flip plus to minus at your speakers to keep everything in phase. I hope this helps?
