so let me see you want to use this state of the art switcher (newer technology) and then use old crappy hum pot in the direct signal path to null out the fundamental?!, you still have noise left because the null does not rid of the harmonics!
no but seriously TK unless you have used what I am using here, How would you know one way or the other what might sound better? or more importantly work better??
At least I have tested both! you wont even think of using DC with regulator why not? cost??
anyways I am LED Biasing the gm70 how should I implement your way?
