What is meant exactly by the description 'more musical'?

Taste there is here...But it is not about taste...

Even stones can speak when you get the stone dimensions and composition parameters right... It become "more musical"... Is the first musician a man with mere "good taste" or a mystical acoustician ?

Is it not "musical" ?

Saying that the man who "sell" this set of minerals pieces of gear had "good taste" say nothing of importance about what is "musical" here ...Setting the minerals right and euphonic and harmonies with the FEED BACK of the ears/brain and the hands carving the pieces of rock describe what is "musical"...

It is applied psychoacoustics before the field even exist !...Or is it a select club of men of good "taste" ? It is " not even wrong" to say so, shamans are a selected club...but saying what is  "not even wrong"  explain nothing  and describing them as having "taste" does not explain  the " musical" healing power behind  music  ... Acoustic did...😁

Dont look for the gear branded name here , be creative... Experiment with acoustics and your own hands ...

Rival atmasphere craftmanship with mere stones but using the same applied science as him in his design : controls of some distortion by carving and chipping stones...😊😉

Taste there is, but it is not about taste ...

Mahgister, thanks for the clarification on "taste marketing", apparently, I did misunderstand you in this issue, which is a relevant point. but, if I am not wrong, here the aim of marketing is to "establish and control" audiophile tastes, not visa-versa, to create gear according to some hypothetical audiophile tastes. 

I also agree acoustics is relevant to the "musicality" but not definitive: Imagine a live concert in an open field or an audiophile that sets up his equipment in an open area.  He has an ideal "acoustics" (which is "no acoustics"), and he wishes to enjoy the music at the maximum possible level of the joy.
