McIntosh MA-5300 is anything but made in U.S.A.
Audiophile equipments made in China have a unique signature, and not hard to identify.
When you can't find country of origin, it is made in China. They are too ashamed to say it. (Equipments made in Malaysia are shown).
You certainly do not see "Made in USA" at the back of
McIntosh MA-5300. I haven't check all of the
McIntosh models. But I believe none of its models has "Made in USA" in the back.
