In Reply to: RE: So how do you compensate for inverted absolute polarity? posted by jeromelang on March 13, 2012 at 16:02:03
When I owned my SA-11S2 I was able to invert the polarity via my ARC preamp. Failing the VAC having the same capability one can always swap the pos/neg speaker cables which would do the same thing.
There is also the lengthy debate on whether or not the recording itself has the "correct" polarity so inverting the polarity at the source, within the preamp or swapping speaker leads may not realize the optimal results on a recording by recording basis...
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.
That doesn't sound right.
"signal flow directionality"
What the hell is this? Never heard of this concept
Don't AC signals flow in both directions?
Also the absolute polarity on most multi miked recordings is a crap shoot anyway.
