    Especially since its a 10 layer board.

    I think that's also why the average DIYer can create a pretty good Class AB amp and linear supply but need to resort to modules when it comes to SMPS and Class D.

    @atomicbob Thank you kindly! The answer was about 9.8x as thorough as I was anticipating (because it came from you... for others, it's about 47x as thorough as I'd expect).

    @Cspirou The magic is not in the switching power supply, it's inside the chassis. I was reading about it earlier, mostly with regard to the ADI-2 DAC, and I figure the Pro has at least as much going on with the power inside as the DAC version.

    From the ADI-2 DAC manual (yes, I like manual pron):
