It is not clear to me that if the manufacturer, in this case Fosiaudio, opens a space for communication with users on its official website, what is the goal. To smile and constantly say that they are the best in the world??? Is it a sin to ask a technical question to the manufacturer whose customer you are? So I asked two questions and no answer to one. I know that in the spirit of Japanese philosophy, when you insult someone, they deny your existence in silence. It seems to me that the younger Chinese have started to copy Japanese philosophy!
