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?

Adampeter,
Here is some reading material that backs up what Al has been saying.

Adampeter,
Did you reverse the polarity at the speakers, or amp yet?

Is so, did you hear any difference?
============

I played around a little yesterday listening to different CDs on my system. My Sonic Frontiers Line One preamp has a polarity phase invert feature which can be switched with the remote control.

As others have posted with some there was no real discernable difference in sound from my speakers. But there was with others. Did I go through all my library of CDs? No.... Just a selection of a few.

Standouts where a definite difference could be heard?

Etta James, "Love Songs".
Track #1, "At Last".
Change? Etta's Voice. Inverted her voice was thin. Correct polarity her voice was full, a more moving presentation.

Chris Rea, "Auberge".
Track #11, "The Mention Of Your Name".
Again the voice of the singer stood out.

Buddy Holly, "From The Original Master Tapes".
Track #20, "True Love Ways.
Difference? Not only Holly's voice, the saxophone as well. Definitely the saxophone....

FourPlay, "Between the Sheets".
Track #1, "Chant?
Difference? The bass drum.
