I've not had a lot of luck buying KFC and then demanding they tell me the secret blend of herbs and spices.Those who have bought PA5 could ask Topping to disclose the Class D chip used in this amp.
After all, they are the owners of PA5 and they may well have the right to know from Topping what chip they used in it. Right? Or am I missing something?
This may well put an end to the never-ending speculation regarding the chip model.
