Polarity with SCD-1

I was just reading the review of the SCD-1 in Stereophile.
It states that there is a problem with the absolute polatity when running balanced that will need to be compensated for by reversing the speaker leads.

I have an all Krell/B&W system, with electronic crossover with quad wired speakers.

Is the above true and what does it mean? Has anybody out there dealt with this (problem)? Would pushing the phase button on the preamp solve the problem.

Thank you,
Richard
