Denon, Marantz, Yamaha, Sony, Pioneer and Onkyo...they are all designed in Japan. It's like a revolving door over there with engineers making the rounds from one company to the other. I don't know where they are made though. Marantz was made in the US a long time ago and then in Japan. I think some Denons are made in Vietnam. Cheaper Onks are made in Malaysia and more up-scale ones in Japan. "Made in" though could mean "assembled in" so printed circuit boards may be coming from China.
