You are right but with an important remark:
One group subordinate hearing eliminating the subjective perceiver to electrical measures , the other group CAN or MAY read a specs sheets but subordinate this measures to the subjective perceiver impressions...To interpret any measures we must do it FROM A PRECISE hearing theory...
In psycho-acoustic which is the science studying perception of sound the objective installation and set of measures are there to serve and study the perceiver impression not to erase it at the end and declare it an artewfact or a deceptive illusion like you said....
Then one group is, if not as deluded than the other, some Amir disciples, perhaps more... Why ? We dont understand human hearing which is a highly non linear phenomenon , with the actual Method inherited from Helmholtz and Fourier....
Then yes you are right the two groups must respect one another, but calling audiophiles "deluded" will not help.... Which is the more "deluded" group at the light of true science in the working not dogmatic science, guess which one? Those who despise the most the opposing group...
Listening experiments are the only personal way to learn how to listen, and anyway is the basis of psycho-acoustic...Not electrical design tools used in the wrong theoretical context...
The human ears is trained in nature recognition sound environment, timing transients are very important in this context and detected and interpreted by our highly non linear cochlea/brain tools...
Then all our dacs for example specs sheets are based on wrong hearing theory reducing all hearing phenomenon to Fourrier method......

it is not me who say that but these 2 mathematical physicists :
Jacob N. Oppenheim and Marcelo Magnasco of the Laboratory of Mathematical Physics at Rockefeller University have conducted experiments indicating that the human brain does not use the Fourier transform when resolving a cacophony of noise into individual sounds and voices.
While the Gabor limit associated with the Fourier transform stipulates that you can’t simultaneously determine a sound’s frequency and duration, the 12 musicians subjected to Oppenheim and Magnasco’s battery of tests beat the limit by as much as a factor of 13.
The Fourier transform cannot, therefore, fully explain the machinations of the human brain. "The actual algorithm employed by our brains is still shrouded in mystery," says Magnasco.
