PYST was the god of drinking in Norse mythology. He would be much better-known if he wasn't getting schiit-faced all the time. Or, well, not really. PYST stands for Put Your Schiit Together, a set of short cables that make stacking your DAC and amp easy.
Put Your Schiit Together cables are nice, high-quality, with solid, reliable connectors. And they are short. And not too expensive.
Important info: The RCA PYSTs are about 15.2cm long, excluding connectors.
