Powered speakers show audiophiles are confused

@kota1 That is a great point, if you spent the money on acoustics rather than equipment. I think the answer is you would be surprised how good some lower priced speakers can be. Paradigm for instance has Canada pumping in lots of money because they are partnered with the government for acoustic research giving Paradigm an unfair advantage against other speaker manufactures. Very few manufactures can afford to build with beryllium. My Paradigm B speakers are 7k each for surround sound speakers but they really hold up as a main speaker with a sub. All to say small speakers with a good sub can sound great. So yes putting money into the room is a good idea, with 1 huge caveat. Acoustics is not a science in that it's completely objective like speaker cables there is a lot of science that can't quite state that this room will sound good. A room that is 12 x 18 x 8 is practically impossible to make sound good because of so many common denominators some rooms have no hope and can't be fixed unless you make them very very dead and move the speakers very close to you effectively wearing headphone with speakers. 

"A matter of personal taste". We both know you need good cables that shield RF and we both know that smart and reasonable people list their cables as components but in blind tests no one can tell the difference, sure everyone has a story about the audiophile who takes the test " ok are we now using the good cables or the bad ones" and they get it right. That is not a good test a good test takes the physiological testing out of the equation. When you look down the grocery isle at the market and see a beautiful woman then you realize it's your wife that is a good honest test, not setting up a picture of you wife and your old girlfriend with all the psychological bagger they both bring into the picture. The things I mentioned in confusion are not scientifically valid unless you are selling them then somehow they have all the science in the world on their side. 

@kota1 Also as far as wireless I assumed you and the man on the video were talking about transmitting the main signal vie RF or bluetooth to the speaker from the wireless transmitter that is a far different story than using a code like FM Play or a format like that using wifi for Roon of something like that is very different than sending the entire spectrum of music via a transmitter and receiver via RF. 

@thespeakerdude Were these wireless connections RF or were they a coded signal like bluetooth or the like. I can't imagine such a cheep circuit in an RF transmitter with no compression. And of course the FCC is squeezing wireless microphones into oblivion with it's huge sale of RF spectrum to large companies and outlawing people with hundreds of thousands of dollars or wireless equipment that just happens to be in the wrong block. The FCC during the last administration was very cruel to people who owned equipment like churches and performing arts buildings that needed good RF. 

but in blind tests no one can tell the difference,

That is a  dead end discussion because people buy what sounds good to them, not what won the blind test shootout. If it turns your crank fine, go get an ABX Comparator from Van Alstine and go for it.

The things I mentioned in confusion are not scientifically valid 

See the above, no one makes buying decisions based on scientifically valid. You mention beryllium tweeters, it seems that mattered "to you". Fine. It hasn't been blind tested against every other tweeter material in the world, so what?

I think there is some science behind the fact people generally prefer a smooth flat in room frequency response. You can look that one up to confirm.

I think you can make almost any room sound good, but not if you have already picked the speakers. Some speakers will be near impossible in some rooms. It's the science of acoustics that makes that possible. The art part is appealing to likes and dislikes.

Is an artificially generated set of reflections from additional speakers any less real than the artificial reflections in a room from 2 main speakers?

@kota1 

I know people don't buy on scientific specs but when you go into a boutique stereo store  there is pressure to appear that you enjoy the finer things in life and to validate your own confirmation bias which stereo stores and magazine marketers are very good at. The psychology of stereo buying and wine tasting are the same, think about that in stereo listening along with wine tasting blind tests don't pass the test but the built up to the psychology fallacies are easy see in retrospect.

"people generally prefer a smooth flat in room frequency response. You can look that one up to confirm." Sorry brother, one of the golden rules of acoustics and studio architecture is that no one prefers a flat room. The speaker DSPs put out a flat curve, this is very simple subtraction and addition to simply make the curve seem flat and the DSP marketing people have let most everyone to think flat is good sounding it's not. Even if there is a good article on Google that says flat it good that doesn't mean it's true, I know that they can't write anything on the internet that isn't true but it does happen some times.
