I think a lot of my skepticism is directly related from understanding enough of the related science, or having friends that do, to understand how misleading a lot of the "science" manufactures give to support their products. Some of it is just wrong while others use accurate buy totally unrelated stuff.
My best observation at my local shop was to point out that they had a speaker wired backwards because one of my familiar recordings had the guitar in the right channel instead of the left. After a short disagreement, they took a look and found an interconnect swapped on one end. It had nothing to do with sound quality, but it didn't sound right at all to me.
