As we are getting ready to hold the improved follow up test, I created a new thread for input:

Speaker Blind Listening Test Part 2 Planning
@Inverse_Laplace and I will be conducting a second blind listening test. If you missed the original results you can read about the blind listening test here: https://www.audiosciencereview.com/forum/index.php?threads/four-speaker-blind-listening-test-results-kef-jbl-revel-osd.25818/ We are...

When I conducted a double blind test to see if listeners can detect the presence (vs. the absence) of an additional ADC/DAC double conversion in the signal path there were about 8 people involved, two to conduct the mechanics of the test with 6 experienced listeners (or maybe 5, it was years ago). After playing with the setup in order to define optimal parameters for the experiment we settled on the following (not really what I would do if I were comparing speakers, though!):
-- length of the stimulus had to be 10 to 20 sec long. Any less, not enough information, any longer, and you cannot remember it
-- replay the same chunk, rather than skip from one version to the other as the track continues to play
-- It was a detection test - two stimuli which could be w-w, w-wo, wo-w and wo-wo, and the subjects had to guess if the stimuli were the same or different, presented in random order
Ultimately the conclusion was that nobody could tell the difference. Never mind preference.
Speakers are much more different, and easier to tell apart. Still, what you are proposing is so subjective in a very specific setting, that unless you can do something to remove (as much as possible) the influences of the environment, it would be virtually worthless to me. Much more useful to the owner of the test location
I guess that if you applied the same Dirac target curve to all of the speakers, then the comparison would be much more valuable to a general audience. These kinds of subjective comparisons only periferaly have anything to do with fidelity, which is what reduces the value of any conclusion for any single individual.

Available on Amazon Music Unlimited (partly) in Ultra HD (higher than CD quality...)... Off topic though, why not start a new thread of "high quality classical recordings" with this.
Thank you for your kind attention on my post.
I have already started these two threads partly relating to your nice suggestion!
- An Attempt Sharing Reference Quality Music Playlist: at least a portion and/or whole track being analyzed by 3D color spectrum of Adobe Audition
- Music for Testing Treble (High Frequency) Sound
Another thread hosted by myself would be also of your interest and reference, I assume;
- Lute Music and Other Early Music: Stunning Recordings We Love
Your visits and participations will be highly welcome.
