No.

the detail photo. So yes, it is now apparent that there is a discrepancy

So are you and Kal, the same and only one person?
He, was the one did the listening, but at no time, throughout his entire review did he point out the absolute polarity reversal issue.
So don't get mixed up, ok?
Also, the other thing is - both sets of outputs were found to invert absolute polarity, so perhaps it is presumptuous for you to say the unit you had for measurement has its XLR jacks wired with pin3 hot. Perhaps it would have been more accurate to say that the unit inverts absolute polarity in the digital domain.
At the time you performed the measurements and wrote them up, you hadn't check the photo in detail before it goes out to print. So yes, it is now apparent that there is a discrepancy. Won't be the first time and won't be the last.
Why do you continue to be insulting? Obviously absolute polarity is very
important to you, but the reality is that other than with purist
recordings, where absolute polarity has been captured in a consistent
manner, it's a crap shoot. Don't you feel that there is room for sincere
differences of opinion here? Or do you feel your own opinion over-rides
all others?I suspect that our sample of the HAP-Z1ES, which was from early production,
conformed to the Japanese convention of pin 3 hot.And again, you are cherry-picking your data in order to criticize the
magazine. You must consider a Stereophile review in its entirety. No, Kalman
Rubinson didn't comment on any differences between the balanced and
unbalanced outputs. But the review as a whole _did_ so so. No, Kalman
Rubinson didn't comment on the Sony inverting absolute polarity. But the
review as a whole _did_ do so.Please try to answer without resorting _again_ to insults.

John, John, don't_get_your_feathers_all_flustered."....I suspect that our sample of the HAP-Z1ES, which was from early production,

That means it is more than just a wiring issue at the XLR outputs.
