i guess we will never know the details regarding the crimson amp, but if one knows anything about the contract manufacturing world (which is vast, global, involving players big and small, high and low, skilled and unskilled), one knows that a brand owner/client can have numerous contract makers, shift and move production many times, do prototyping in one place, volume ramp up in another... it is not so simple, details matter, generalities often meaningless, exceptions are the issue
