Why don’t more members post their systems in their profile?

I don't, simply  because my room and therefore my setup is terrible. I don't need to be reminded.

I was surprised at the number of high dollar systems that aren’t in dedicated spaces with the importance of the room.

I can only speak for myself, but I prefer a multi-use type room since I am often engaged in other activities or projects while listening.  The room acoustics seem suitable, probably based on the size of the room and high'ish ceilings, wall insulation, carpeting, upholstered furniture with wool batting, and a few wall hangings.  Another thing that helped with bass response was moving from larger floor-standing bass reflex (ported) type speakers to still large'ish, almost full-range, stand-mounted, acoustic suspension (sealed box) speakers and then adding two subwoofers that can be adjusted to dial in appropriate bass.  This set-up virtually eliminated room-related bass problems.  

For me it's a privacy issue. My gear is not in a dedicated room. I list my gear but no photos of the system.

There is a single photo of what you can expect to find should you enter my home. 

If anybody broke into my place, they’d probably feel so bad that they’d leave a $20 on the equipment rack - and start a GoFundMe page for my system.
