Even if one has the luxury of a dedicated room and or wife approval, all this stuff looks ridiculous in your house.
I invested in some of this stuff. Expensive, but can be setup in a minute. My gear is in a living space, so for serious listening bass traps behind the floorstanders and panels on stands for 1st reflections. Instant "almost real" 3D sound.

If one has the skills and time, you probably can DIY for much less.
When Im done, it all goes back in the closet.
