Hello, I am considering buying two Fosi Za3s for the end of the year to do dual mono mode. I already have an Aiyima A07 that I modified a little (replacing the AOPs with two SPARKOS LABS SS3602 + changing the 4 inductors + red WIMA capacitors - the sound has improved a lot compared to the...

Hello, it's true that I had no choice but to solder the Inductors from the bottom of the board, because this was just too big to be soldered next to the other components on top. In any case, this is hardly important because the whole will be put in a larger box with the power supply. I tried...

Well, I'm happy because the sound is even more pleasant now, it will have been useful to replace all these components.

Hello everyone, I had a question to ask about this Aiyima A07 amp: I plan to replace several components as "trungdtmc" did. I only know a little about electronics and I'm afraid when desoldering the two 1000uf/50V capacitors that they remain charged with electricity (because I would have tried...
