Blindfold Speaker testing

Long time ago my brother auditioned speakers in audio store. Salesman stated that first speaker is so good, that basically there is no need for anything else and it sounded good indeed. Then he presented more expensive one just in case "if my brother’s hearing apparatus is superior". This speaker sounded better than the first one. Then he presented top of the line speaker that sounded wonderful. He left my brother in silence for 5 min. serving other client and then offered one more speaker that is less expensive, but as good sounding as the top of the line one - a real bargain. It sounded great and my brother bought it. He found later that it was the first one he listened to. It was twenty years ago, but he still likes them (Cabasse).

There are so many factors involved, including suggestion (placebo effect), passing time, amount of time in between, music piece etc. that it is difficult to tell the difference. I’m pretty sure all speakers don’t sound the same, so Richard Gray’s experiment shows only uselessness of the method.

They are posturing as members of the rich and famous.

Kinda sums up the whole thing. Coveting others.

Look 
 High quality midrange has been around since the 1929  Field Coil, Colortura made in the USA, Chicago. 
I've not heard such pure midrange in any modern speaker.
Sure not all FC's  post this 1929 were as pure in midrange, 
All I am saying is  high quality midrange started as a  Field Coil and  now its  going full circle back to Field Coils. Back to where it all  began. 
In 20 years every speaker will be FC;s,

music piece etc. that it is difficult to tell the difference.

Oh for sure, Some  retailers have the sound room so perfectly set up, you'd buy a  set of Bose.
Test cds make a  huge impression on the unsuspecting, room treatment, thick carpet, 
Its a  trap. 
It took sometime to get a  understanding in these cheap full range, At the 1st I loved brand X,,,well then onto to brand Y,,hummm, Y was superior, last I added a  david Louis, 4 inch, blew away the other 3 full range.
Now  I can hear the DL is OK, not worth any more than the $200 I paid, = You get what you pay for.
But surely these DL 4;s offer a (much) better sound stage than your average xover box thing. 
There is something about these full range technology which require no xover, that allows more of the music to pass effortlessly through the speaker.
xover things can not compete. 
I am quite sure the David Louis higher end speakers are even better, But I'm not interested in 2nd rate any longer. I am going for  The ~~top dawgs~
At this point , why settle for less?
Cost me about $500-$600  in the FR testing experiement.
With that completed, now i am fully convinced high sens/full range is the only speaker for my music. 
Will they beat out the Seas Excel in the bass? 
Can't say. 
Or the Magnoxov horn in the highs?
 
We have to keep experiementing til we find the ideal equation.
And we share our findings here. 
If there was a dome tweeter that made mids like the 1929 Colortura, I;'d have it in my system. 
Only a  high sens can reproduce these fine mids.
