Put another way; if a system is phase correct and a recording has sounds out of phase; your system reproduces for your ears to hear, what that out of phase music sounds like. That reproduction of the out of phase sound is in phase. If you reverse your speaker cables that sound is not in phase. You are hearing an out of phase sound, out of phase. It may end up sounding even worse.
Phase inverting preamps
Apologies in advance for this newbie question. I was reading some reviews of preamps and a couple said that the preamp "inverts phasing" and that this would have to be accounted for elsewhere in the system. I know what phasing means, but how and where does one allow for it elsewhere in the system?
