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,

To avoid having to switch polarities for different equipment, this is what I did. Most US equipment uses pin 2 hot versus the pin 3 hot config on (most) Japanese equipment. What I did was have Cardas reterminate my balanced Golden Reference cables - at the source end - to make the SACD output phase correct with the rest of the equipment. It's important to do this at the source so the + and - legs both use the same conductor. Often ground/shield is a different material from the signal bearing parts. Also, the Sony generates its balanced audio signal thru a series of cheap op amps, many prefer its signal ended operation as purer. YMMV. How's that for anal?
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.
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.
