I have tested Yamaha U1 pianos from before they moved production from Japan to Indonesia and U1 from after, and they don’t sound as good.
“Moving to China” is not merely a change in production locality, it’s a statement regarding how the brand is defining its cost vs. quality tradeoff.
Quality management (aka checking that product complies to specifications) is expensive no matter how cheap the labor force is. When they go chinese, usually they cut on both.
Not to mention, my Thinkpad has been my most expensive and most annoying computer so far (first time I had to replace a keyboard, and only after 2 years, then had to replace the screen at 3 years - couldn’t even find genuine Lenovo spare parts).
