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

The ‘distortion product’ isn’t responsible for shaping or determining all of the various parameters that must be satisfied for a product to be considered musical. I don’t think that you are saying that it is, please clarify.

@rooze Actually I was saying exactly that. Distortion of any amplifier is also its sonic signature. Do you know of a musical amplifier? It has a musical distortion signature, likely with prominent 2nd and 3rd harmonics.

@rauliruegas Perhaps you could explain how deciBels, which are often called "volume units", are the result of taste rather than human hearing rules. 3dB is a doubling of power in an amplifier, but barely audible as a volume increase, are you saying that is something learned??

@atmasphere Ok, got it. I will have to think more on this. Example, I’d considered PRAT a key component of ‘musicality’ but it would never have occurred to me that PRAT could be a function of an amp’s distortion product or signature.

Well, one must consider the wide range of distortion possible in the amplifier, indeed the whole chain… it’s mostly dominated by the transducers… and IF you can hear it includes temporal and transient distortion…. 

While the dna code we all run is very strong… we are not identical… after all there are…some people with perfect pitch….. perhaps a small allowance for the existance of God…

Fatigue free PRAT + 

@atmasphere  : You insist on the same " technical " terms and yes volume is comething we learned and it's our taste who defines the kind of volume we like.

You just don't understand the whole explanations I posted or just don't want to understand but everything is already said.

Useless and futile to follow this non-fructifer dialogue and before I be less polite with you: bye, bye and Happy year-end Holidays and for the other gentlemans too.

"Musicality" in any system vary a bit with variation of the parameters which are numerous, electrical, mechanical and acoustical and also which are related to the gear design and not only to the way we embed it ...

Then if the gear amplifier is not "musical" by design with the recognized harmonic pleasing effect missing to begin with , no electrical or mechanical or acoustical work will change it ... I take atmasphere point in this way ...But at the end musicality is the well balanced sums of many factors , which are not of equal importance for everyone at the same degree... Then in this sense taste matter or taste there is for sure ...

But at the end musicality is a subjective perception objectively controlled by the various controls we can exercise on the three working dimensions and on the gear design by knowledge and new technology ...Nothing less nothing more...Then in this sense even if taste there is, just mere taste it is not ....

Musical is then and adjective which cannot be defined only subjectively nor with only a short set of electrical measures, it ask for psychoacoustics more deep knowledge and objective recognized factors as for the point raised by atamasphere about harmonics and distortion which is only a psychoacoustic fact ...

I dont understand why Raul dont accept this elementary fact ...

It seems psychoacoustics which is a deep science investigating sound qualities and doing so, transcend the separation between object and subject by putting them together in one or many experiment escape the understanding of some  objectivist as well as  some subjectivist audiophiles ...

Anyway i wish to all a warm christmas... 🎄
