I also question the sanity of anyone spending that much on equipment and seemingly nothing on room treatments. If your goal is accurate sound reproduction, your room is going to be one of the biggest sources of problems (phase smearing, standing waves/room nodes, flutter, etc), especially in smaller square-shaped rooms. Spending $10k on a sound system and zero on room treatment is like putting monster truck tires on a lawn mower. It's no coincidence that studio control rooms, especially ones that do commercial-quality mastering, use all kinds of room treatment tricks to ensure the mastering engineer can accurately hear everything in a mix.

And while I don't think audiophiles are just about spending money to impress friends, sometimes they go about things in incredibly inefficient ways and pretend they are not susceptible to placebo effects.
