Very surprised by these responses. I'd have thought that audiophiles were compulsive perfectionists who never do anything with their systems that they can't justify with elaborate arguments.
For me, I list components in order of their importance for sound quality. Therefore, speakers first, then the room, then amplification, source, cables, etc. The "etc." includes silly tweaks (cable risers, Schumann Resonance Generators, and so on).
I do have a virtual system, by the way, with 25 pictures and a narrative of over 5,500 words. But I've long since closed it to general viewing.
