Need definitions of: Dark; Warm; and Bright

Audiophiles have been using these terms with these meanings for decades

For sure these words means something , it is related to the way the relation between some higher harmonics convey the sensation...And all audiophiles can correlate these words to a meaningful sensation.... Saying the opposite would be amateurish or ignorant....

But one this is done, and when others audio factors enter in play, these words are no more enough to characterise audiophile experience in all his dimensions adequately...

Saying that tubes may be warmer and S.S. may be most of the times brighter dont push us way much along the road...When the amplifiers is in the room we must begins to embed all audio gear together in the system, in the room and in the house, taking into account the mechanical, electrical and acoustical working dimensions...

That was my point, not negating the rightful and meaningful content linked to these words use...

Then dont put in my mouth or suggest what i never say: that these words are meaningless... They have a meaning related to the electronical design market of amplifier or speakers, tubes are generally not S.S. sound quality for example ...But others factors plays in acoustic to amplify or to decrease these warm or brighter impression...

But no acoustician characterise a room to be warm or bright...A room can be dead or too much echoing...It is related to timing or reverberation time not to amplifier rendering of harmonics etc...

No musician evaluate sound musical timbre by warm and bright characterisation MAINLY....

When a piano make different timbre impression in my room, when i change the acoustical settings of the room or if i modify the vibrations controls of my gear, or if i modify the electrical noise floor, To describe the result beinng "warmer or brighter" concepts are no more very useful and dont relate well or much to the factors in play...

It is one things to describe sound by some of his aspect for example relation between harmonics envelope of a timbre perception and describing with words all the variables implicated in the perception...We need way more words that warm and bright which related mainly to the electronical design market of speakers amplifiers or dac etc...

It was my point....

To say it in a short way, people must learn many others concepts and not evaluate system with this meaningful but limiting words only... Audiophile experience is linked to many factors not only 2....

I hope it is clearer....

By the way with your experience i will not teach you anything here.... You know way much than me in audio ....But i only expressed here in these 2 posts my limited but insightful personal experience for the sake of the discussion .... I apologize sincerely if my post seems to give you lesson which i am perfectly conscious you dont need at all from me....But i spoke my mind for the discussion ....

my best to you...And my deepest respect....

The fundamental issue in this conversation seems to be "which words can be used to describe audio experiences accurately that other people can also learn?"

It would be completely right if sounds and music experience would overlap completely but they are not...The vocabularey of sound in audio thread is not identical with  the vocabulary of music and acoustic... Then you are right we must have common words to communicate.... But some experience cannot be described by some of the words we use in audio more often... Like "bright" or "warm"....

Then the vocabulary for sounds in audio threads come from electrical design particular tasks and marketing and not from experienced musicians or musical field...

Then appreciation of a system through some kind of music differ anyway much from another kind of music particular requirements...Classical brain dont judge like rock brain....

For example "warm and bright" comes from the electronical condition particular design of the gear links but timbre interpretation and description come from some core non amplified instrumental and vocal music experience...

Psycho acoustic dont use much the audiophile "warm and bright" expression at his core .... Audio thread do....

These concepts made sense ONLY for describing our relation to sounds in a very particular way.... when our system BEGINS to be rightfully embedded in his working mechanical, electrical and acoustical dimensions these words make less and less sense, or we dont need them at all no more.... Even when the fine tuning of a system only begins they lost their importance when comes the times to describe the system translation of sounds into musical perception...

People use them 2brighter or warmer" in relation with a non tuned system out of the box in comparison with their past experience of another system or piece of gear.... For example these speakers or dac or amplifier are warmer than my last one....

But musical acoustical tuning cannot make them very useful more than in a very general almost useless way....

"Timbre", the crux concept of musical perception, is not, ONLY and MAINLY, a bunch of frequencies for the human ears.... Acoustical controls and is more important for example than the design of an amplifier most of the times , save if the design is very bad....And the vocabulary of acoustic cannot be circled with "warm and bright" concepts...

Some acoustical concepts like " imaging", "soundstage", "listener envelopment", "source width" etc keep their meaning more supported in a string of experiments....For example that make no sense at all for me now to describe my audio system with bright and/or warm words, even if i want to describe my taste... I will more easily say that piano timbre is natural the sound distributed out of the speakers distinctly and in a room filling soundstage where i feel sometimes included in the recording theater....Bright? Warm? yes when my acoustical settings are out of tune if i eliminate them the result will be one of these 2 catastophes in loosing the natural "timbre" sound of each instrument...

My best to you and all...

Alas, the technology to create these magical plots is beyond most audiophiles.

This audio vocabulary refer to the modern creation of electronic design audio....It never exist among musician before that ....

Music is not ONLY  pure physical sound, music is an interpreted phenomenon and if a an audio system is defined mainly  by warm and bright audiophile concept, we are in very shallow waters....

Musical sound are not warm nor bright ever....Save if the audio system and the acoustical settings are uncontrolled or badly designed or the 2 at the same time...

A musical instrumental timbre is never bright or warm "per se" save if the system is not appropriately tuned...

Then defining our taste by warm and bright qualification on a "magical plot" or by ears, refer to the same ignorance about neuro-acoustic....and refer to our gear defects  not to musical perception...

Musical sounds are not physical sounds.....
