Sounds like a lazy customer support person, complete made up BS. Not only should you go as high as you can in the crutchfield command/customer support structure, I think you should document and carbon copy everything to Technics AND Panasonic as well.
Every company worth its salt has a good complaint department. Sounds as if crutchfield just wants you to go away...
I just can't believe in 21' that in the metal lathe platter cutting department, Japanese cutting specs/tolerances to be so far off with digital/microscopic technology?
