I concur with both Almarg and Zargon, Bernie is incorrect. Once the phase is inverted, it does not magically 'uninvert' on it's own. If the preamp inverts and the amp inverts, then you are back to absolute phase. One more option could be an inverted source. An inverted source with an inverted preamp and a non-inverting amp would also produce absolute phase.
To make it simple, think of absolute phase as a '+' and inverted phase as a '-' . 2 X '-' = '+' , 1 or 3 X '-' = '-' .
You can simply change the '-' to a '+' by switching + and - on your amp terminals, no big deal.
Of course since 50% of recordings are recorded out of absolute phase, it really shouldn't matter at all.
Cheers,
John
