Just a guess there will will be posters that will say they can not hear any differences.
Another problem, how may recording engineers today, for that matter for the last many years, take the time to check absolute polarity of all the microphones before making the recording? Are there any recording engineers that take the time to check today? Recording engineers like Doug Sax are gone.
I have CDs that were mastered many years ago where some tracks are recorded in-phase polarity and other tracks on the same CD inverted phase polarity.
