A reversal of polarity between XLR pins 2 and 3 at some point in the signal path would result in diffuse imaging if and only if it occurred in one channel, not both. Presumably a component design in which pin 3 is the non-inverted signal and pin 2 the inverted signal (which is the opposite of the usual convention in the USA and various other countries) would do that in both channels.
Also, given the reference in the OP to excellent sonics (which would certainly be compromised big-time if a polarity reversal was present in one channel), and the level of sophistication that a user of a Maker Audio product can be presumed to have, I would expect that a polarity reversal in one channel is unlikely to be the cause.
Jeffga, what preamp and what speakers are you using? And is there a subwoofer in the system?
