Topping should solve these issues and withdraw affected SNs from the market, ESD is not a reason for electronics to die in 2021, I watched Linus/Electroboom videos and it shows that with a good design it's really hard to kill electronics with ESD even sensitive devices like RAM so Amps should be way more resilient. Personally I don't want to risk my headphones and these problems made me discard L30 and look into getting something else especially with the last price hike. I hope A30pro is a better design.
