Preamp inverts phase question:


The owners manual of my preamp indicates that the preamp inverts phase: the circuit is phase inverting. Does this mean that I need to hook my speaker cables up backwards to correct the phase inversion... do I hook the positive speaker cable to the negative speaker binding post and visa versa with the negative speaker cable connections on both speakers?

Benie,

If my preamp inverts and my amp is non inverted then there is no need to correct the phase is that correct?

Almarg,
So...then it's a 50/50 shot as to which phase to use; by reversing my positive and negative speaker leads (correcting the absolute phase inversion) some recording will sound better but, some may sound better with an inverted absolute phase. What then is your recommendation: to correct for absoulte phase or to allow the phase to remain inverted?
Kusina,
My preamp is always phase inverted; no switches to go back and forth to switch phases. It is a Joule Electra LA-150 MK2.
Regards,

Okay, so for someone much slower than the rest of you... If my source does not invert, my preamp inverts and my amp does not invert my sysytem should be in absolute phase right? This way, my sytem would be set up properly for recordings that have been recorded in absolute polarity (although many recordings are not.) If I then wanted to confirm that my end result is absolute polarity would an absolute polarity checker accomplish that? (My amp is french and they are terrible about responding to inquiries) so, I am not 100% sure that it does not invert phase and would like to be able to confirm my end result with such a tool if that is what the tool is intended for.
Thank you: Dan ed, Benie, Almarg and everyone else who took the time to help me with my understanding of these principals.

Jea48- I did experiment today. However, I was frustrated because I wasn't certain which of my CD's were recorded in absolute phase. My plan was to listen to a cd that was recorded in absolute phase and switch back and fourth; picking the set up that sounded the best. However, without being certain about the recording I didn't see any point. I sent an email to Pierre at Mapleshade and asked him which of his cd's that I own were recorded in absolute phase. I plan on figuring this thing out!
Will the mono setting on my preamp help me in any way to determine correct phase via listening tests?
