I'm a little sad that they didn't link the obvious original inspiration for that test - this classic Audioholics forum post by Bob Dean from 2004: https://forums.audioholics.com/forums/threads/speakers-when-is-good-enough-enough.2512/page-2#post-15412 https://forums.audioholics.com/forums/threads/speakers-when-...
