While you are correct about Luxman's current Chinese ownership, quoting from the
US distributor's website:
"Since 1925, Luxman has crafted audio products in Japan. Luxman products are designed in Japan; each part is carefully tested and evaluated with many custom-made parts, thus making the Luxman designs unique, special and one of a kind. Apart from the shared Power Supply, the amplifier designs are usually dual mono. The transformers are made in Japan to their specifications. Luxman even hand selects the color paint used on the resistors to identify value and tolerance based on extensive listening tests. The chassis is carefully tuned with both vibration and resonance being very carefully controlled to make them perform like a musical instrument. Finally, assembly and testing are carried out in Japan. Luxman's attention to detail is second to none."
