So, fredos, do you have any practical advice for all that ?

Now I am starting to be worried about power supply decoupling since my pcb layout has some issues, and is it normal to have voltage pumping effect on just positive rail supply when playing freq. below 100Hz ?

Positive rail gets bigger and negative gets lower when bass kicks even if I use 2A regulated lab. supply and 2x10000uF caps ? Is this completely normal ?

... well now it is kind of paused, because I have some college obligations lately. And it has some sync. issues and crosslistening problems beetwen two channels and LC filter is not calculated for out frq. more than 15kHz so I will need to redesign it.

For now, like I sead it is in 'frozen state' and I have finished ~80% of zappulse 2.3 rev.eng. so I will take some ideas from there . . .
