Default Component selection for best performance (LM3886).

My amp sound's pretty good overall, except from one thing, the high tones and vocal's is sometimes to mutch.

As described in the datasheet, i added a 220pF cap between leg 9 and 10, and as an extra i added a Zobel network (2ohm -> 100n ->GND) at the output.

Now, the high tones and vocal's sound werry good. BUT instead the overall sound is more flat and not so dynamik as it used to be, and that takes away a big part of the joy.

So what should i do? I guess that i have to calcullate more exactly whitch value i need instead of the 220pF cap, but how do i do that?

Please give me some advice.

Best regards...
