Got an old Denon CD player which I terminated but not before doing some tests. Besides SM5840 and 2 x PCM61 it had the often found dual tracking regulator M5290P. It came to my eye that this regulator is pretty silent.
Never thought about that. This is a regulator of at least 25 years ago. Check that datasheet!
