Are audiophiles still out of their minds?

I'd like to learn more about room treatments. Is there a commonsensical white paper or simple, rule of thumb article you recommend? 

Please don't steer me to threads that are a series of arguments. That kind of thing wears me out.

Thanks in advance,

Over at the Planar Speaker Asylum forum there is a lot of discussion of room acoustics and treatment, understandable because of the nature of planar speaker's interactions with rooms.

I'm wondering, why all of the hoopla over expensive wire/fuses? Why don't we fuss over acoustic treatments more?

I'm far more in agreement with you on this than not, relative to some aspects. Room acoustics is a big factor and contributor to the overall sound of ones audio system, but I much prefer tweaking acoustics with "natural" environmental aids than those typically pre-manufactured that absorb sound more than they diffuse. Diffusion to my ears leaves a vital element of energy and "aliveness" intact, though a certain (preferably minimum) amount of absorption seems necessary. Taste is another factor, I guess; to me the threshold of the level of absorption hits earlier than others, but where the reverberative nature of the acoustics may still be too prevalent I seek to minimize via diffusion. It's a balance that takes some trial and error to attain, where my preference into acoustical behavior is tilted towards that which is slightly more alive/reverberative. The careful arrangement of plants, bookshelf, rugs (a big cow skin on a wooden floor in my case) and furniture can bring you a long way - indeed I prefer natural materials to achieve this. Added to this my speakers are all-horn equipped which makes them more directive in nature, and so downplays some much of the contribution of the room. 

Phusis, although you can try "natural" acoustic treatments as you describe it, they are nowhere nearly as effective as absorbers and diffusors that are made based on mathematic calculations from acoustic theory. For example, book selves filled with books do minimal or no diffusing. I was dissapointed when I found out.  Believe me, I've tried using plants, rugs, bookshelves, couches, etc. In a problematic room, these don't come anywhere close to real diffusors and absorbers. 

Uncledemp, all of my acoustic treatments come from GIK Acoustics.  Go to their website which has plenty of informative material on acoustic room treatments.
