Correct Way to Invert Phase

Hi,

My Conrad Johnson preamp is phase inverting.

The CJ manual says to change the phase "...by reversing the positive and negative connections to your speakers (be sure to reverse both channels)..."

Can anyone explain why changing the positive and negative connections between the amp and preamp would not accomplish the same thing?

Just wondering if this could harm the components or is some other science at work here that I do not understand?

Thanks for listening,

Dsper

Absolute phase vs relative phase aka polarity used loosely :(

The use of a single gain stage means that the L3A main outputs (but not the buffered tape and surround-sound outputs) invert signal polarity. Since no phase-inversion circuitry is used, be sure to reverse speaker cable polarity at either the power amp or speaker terminals in order to maintain correct absolute polarity.

Hi, 

This is for audible illusion and it is on reversed polarity and fix to reverse speaker cables.

Conrad Johnson refers to phase or polarity since they are different topics to my understanding albiet not the first time I am wrong ?

Cheers.
