I was just reading again page 15 of the datasheet of LM3886 regarding grounding technique. It is frightening to know how difficult it is to make a correct pcb for LM3886 or for the same reason for any audio amplifier. Every ground connection of any component should be returned to the star ground. In a pcb it is almost impossible unless it is multileyer.
Yes, yes it is possible for a circuit with single LM3886 without buffer or dc-servo. I should have mentioned that. At the moment I am struggling with a parallel of two LM3886 and with other addition mentioned above (though again and again I am reminded that those are not necessary).
