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

My Krell preamp (KRC-HR), has a phase switch that the owners manual says inverts polarity 180 degrees. Will this solve the problem?

(By the way all my Krell units have correct polarity with pin 2 being hot. The Sony has pin 3 hot.)

Yes, the phase switch will solve the phase issue but not the way these units (not just the Sony) generates a balanced signal.

Ivanj,
What does the 2nd half of your sentence mean?

Quite a few of the recordings are out-of-phase anyway. The easiest thing to do is to use the phase inversion switch in your pre-amp, just toggle it and see whether you can hear a difference. I do that all the time. There is no need to change any cable connection.

LAte night truncation of thought...what I mean is that the Sony is not a purely balanced differential design throughout. And the phase inversion switch won't make up for that.
