Most rooms don’t need acoustical treatment.

Of course. Because that is nothing to do with it. In fact, of all the different ideas audiophiles have about what they are trying to do, to recreate the sound the recording engineers heard in the studio has got to be the furthest from it you can get! 

I mean, think about it. Sinatra-Basie was done back in 1962. Are we supposed to have systems that make it sound like it did coming off those 1950's era speakers? With all their colorations? I don't think so! 

Some think the goal is to recreate the sound of the original performance. This is a little closer to the truth. This is also probably a lot closer to what the producer and recording engineers were trying to do. Capture the sound of the performance. 

But still, not quite right. Closer to the truth to say they are trying to capture the spirit of the performance. The feeling. The vibe. Otherwise, why place microphones inside drums, and stuff like that? See? Who ever sat with their head inside a kick drum?   

So why on Earth would anyone talk about recreating the sound heard in the studio? It is nuts. 

What they do instead, they create art. Auditory art. Just like Picasso did not draw a woman to look anything like what you see with your eyes, but he did somehow capture the spirit of woman. Not "a" woman. Woman. That kind of thing.  

What we do with our systems is put our auditory art on display.   

I was in the home one time of a man who was really into Remington. No not the guns, the bronze sculpture artist. He must have had 20 of them, with the best ones in a living room. Wired with lights and a panel he could push a button and the lighting would fade out on one and fade in on another. Or several at one time. Just amazing.  

Probably Remington never had anything like this in his studio. Probably Picasso never saw any of his paintings under MOMA lighting.  

I wonder, are there art snobs who would sniff at how they were there in the loft and they never have seen any of his paintings that looked anything like what they did there? A perfectly good metaphor that shows how silly it is to try and recreate the sound in the studio. 

I am by nature a skeptic. And many things (IMHO) in the audiophile world are indeed snake oil.
That said, in my 13x16 living room, couch chairs and all… I bought two 24x24 box difusor’s and sat them on top of a chair back, which sits between my speakers, no doubt about it, hands down, immediately beyond a reasonable doubt completely changed the room dynamics for the BETTER. The sound stage suddenly had depth and basically a larger presence.
I was truly amazed.

my rooms have furniture and clutter.  These rooms don’t really have a need for treatment.  It’s snake oil, voodoo science.  

If your furniture addresses all the acoustical issues in your room, yes. However, that is somewhat doubtful. Many home theatre setup have auto IQ systems precisely because very few rooms are acoustically neutral. 

I'm normally a person that scoffs at measuring equipment as my ears almost always proves the measurements to be of no value, but acoustics is an area where measurements by and large correspond with our hearing. 

If you take a simple sound pressure meter (i.e. decibel meter), you can feed different frequencies into your system and measure the sound pressure (volume). You will see swing of 20db, 30db, sometimes even more across the audible frequency range, and these swing will be differ in different areas in your room. 

Addressing some very simple things, like the first reflection point will dramatically increase the focus and sound staging of your sound system. The changes are not subtle. You'll be bowled over by just how good your system really sounds.

Ps. A little stone or clock in the corner of the room isn't going to do it. Have a look at what the pro audio guys do.

It is kinda funny when guys spend thousands of dollars on power cables and such, but refuse to spend a dime on the room.

If we were smart, we’d spend 50% of our budget on our rooms. But we aren’t smart (myself included)

Even though I know it works as I have experience of it, I loath to spend $500 on diffusers but will happily spend $2,000 on power cables. 😂🤣

Not sure I agree with you there- that it doesn't matter.  While its true those of us without direct studio or live music experience have an extreme challenge knowing for certain what is sonically  "correct", I think the goal of many audiophiles is a piano needs to sound like a piano.  Many of us have heard a real ones so not the impossible target. 

Some room treatments are ill advised and don't help, but it is true that the speaker and room are a bonded pair.  One influences the other in more ways than most understand including most manufacturers.  The science of acoustics and sound is not simple, easy to explain or linear.  Just trying to explain a decibel gives most us a brain freeze, and the entire subject of how a the environment influences a speaker can be a lifetime of study.  It truly is a rubik's cube.
