These are the elements, more or less, with BOLD more important ... and I ask you op...
How could anything be standard in this? There is no standard.
People who want standards are on the perfectionist side of the spectrum, the scientists side. You all come to music because music is the universal language of humanity. It’s not a science project to set up a room, it’s a journey into the self. You want to leave your bias in the supossed land of no bias but you are afraid.
Embrace the unknown, and the unknowable. Have faith in yourself, not fear of missing out.
(As far as mastering rooms that use tube amps, I have a successful and well known example right in front of me daily, but yes, they are in the minority as it’s a PITA.)
