Why or when would I ever choose to listen to the inferior ones?
Different presentations, different perspectives, equally valid and not necessarily inferior. Audio, especially vinyl audio, is an exercise in aesthetics, not epistemology. I'm always surprised and mildly amused by those who seem to define it as a mission to find the one truth.
I view my multiple tables, tonearms, cartridges like Kurosowa viewed reality in Rashamon: a matter of perspective, each one compelling on its own terms. Part of the fun is working with the various combinations until they realize their own coherency, they're own flawed perfection, their own best character. Then they speak on their own terms and I'm convinced by their narratives.
