Most rooms don’t need acoustical treatment.

DSP is just a tool, which most professionals use as part of their toolkit. Room design, acoustic treatments, speaker location, and DSP together is the best solution for most. Sometimes you can’t treat the room, sometimes you can’t place the speakers where you want to.

I agree with you...

My mechanical equalizer so powerful it is cannot be used in a living room and setting it by ears is not for everyone... Not much more that setting a piano strings is for everyone...

But i learned much in the process about speakers/ room /ears relations...

Audiophile experience is here not in electronic design upgrade...

Acoustic is key but you know yourself already that...But most did not....

 Thanks for your numerous interesting threads....

Electronics and speakers are at most 50% or less and the other 50% or more is easily the room. But, we seem to have ’know it alls’ like the OP who seem to think the room doesn’t matter. It is kinda funny when guys spend thousands of dollars on power cables and such, but refuse to spend a dime on the room. For instance, if the upholstery on your big couch is leather or something else will have a much bigger impact on the sound than if your power cable cost 40 bucks or 4000 bucks (facepalm!).

You clearly have not heard very many power cords. D'oh!

Power cords in a stable supply of power seem like snake oil.  Other things are better pursued.

@millercarbon - @jumia has not heard many power cords in even a middling quality audio system.  Sheesh.  Why are there so many posters who don't believe that cabling sounds significantly different?   Don't they have something better to do in their lives?
