Just wanted to follow up here. Amir measured a difference on channel 1 and 2 with quite a bit of increased distortion on one channel.
We can see that here:
In our measurements before we sent the unit there was only a minnor difference and the channels tracked much better in the THD+N measurements. We measured the unit again when it came back and the result was the same as before we shipped it out. The result can be seen below.
Our measurements are conducted with the R&S UPV audio analyzer.

A possibility of the difference migh be related to the alligator clips and the grip. We struggled to get consistent results before we moved to alligator clips with rhodium. After that, the results have always been consistent.
While the difference in Amir's measurements is unlikely to be audible, it's something we thought was worth pointing out as we strain to get the very best the measuring results.
