@jbthurston The Wilson is "a statement of the art" from one school. But there are many other approaches, which date back to before WW II and are still actively pursued today with components that require one to assemble and voice a system, typically horn-based with low-powered tube gear—truly a different world.
This is a parallel universe--often referred to as the "underground" that is made up of equipment that people today would likely call "DIY" but which occupies a place that is just as revelatory but is not part of the commercial eco-system that provides the churn for the legacy press.
