New high resolution SACD releases, players and technology.

you may have compensated for inverted absolute polarity

But you had reversed the signal flow directionality within your arc amps, by engaging its analog domain polarity switch, which is even worst.

Even if you were to invert the absolute polarity digitally on the newer marantz SACD players, you'll still subjecting the XLR interconnect cable between the player and the pre-amp to reverse signal flow directionality.

People who had done the comparison below found that sound is different, even though polarity is the same in both cases.

1.  SA11S2 polarity switch engaged (180 degree polarity invert), player end of interconnect wired pin2 hot
2.  SA11S2 polarity switch disengaged (0 degree no polarity invert), player end of interconnwire hanged pin3 hot

That is because signal flow directionality is far, far more audible.
