In this episode, PS Audio design engineer Darren Myers takes us through the process of designing printed circuit boards, which are known as PCBs. It turns out there are tons of considerations in play when selecting the material of a PCB, and determining the position of components and the makeup of the traces. Listener questions about tweaks and credibility are answered, and this week's album recommendation is a fascinating release from a pair of producers who craft sonic landscapes only from recordings of one instrument -- in this case the upright double bass.
