I will buy an O2 pcb board and will build custom case. It will be kind of desktop version of O2. I only have experiance from a cmoy. Have couple of quastions about building a new O2.
How can i make an O2 to take power direct from AC? I think transformator can fit in the battery section which will be empity(we take power from ac). But not shure how to connect. And which transformator? 20, 25, 30? Quality of this part effects sound?
I also want a 6.3mm balanced output, rca inputs. Also don't know how to connect.
Do you have any recommendations to changing parts to have better sound? Like better or higher capacitors? Better connectors?
