How do you add color?

"colour" as qualitative word associated with the gear component is one thing...

"colour" as a qualitative concept in acoustic and psycho-acoustic associated with TIMBRE is ANOTHER thing...

I cannot be clearer and shorter...

Confusing the two muddle the problem...

Gear colours as with dac that are of different type or with amplifiers S.S. or tubes is a synergy and design qualitative coupling problem...

"Colour" as with tonal colour associated with TIMBRE experience is the main problem in audio with the spatial aspects of sound independently and this independently of the price tag of your system .....

No recording reproduce a perfect experience of timbre only a specific one in specific recorded location of the musician in the room and with some microphone location and typ;  our room acoustic translate this imperfect recording of timbre and the spatial recorded information  cues into our own room acoustic ...( Speakers crosstalk muddle this information about timbre and location and other spatial acoustic concepts )

The best gear in the world in a very bad room will be less desirable than less costly gear in an optimal room... This is a fact not my opinion...

Now if we want a better TRANSLATION of the specific acoustic trade-off conditions in some specific music recording, we must create a room able to optimally make possible this translation , nevermind the relative qualitative variability of the gear components ... It is acoustics domain i spoke about ...

The gear pieces are more or less optimal for each one of us to convey this recording trade off choices as an analog/digital information processed line for sure, gear matter for sure , but they will not beat the room conditions for this acoustic TRANSLATION from the living recording Hall or studio into the acoustic conditions of your room...Acoustic room conditions change impact way more than a dac change in most case..

TIMBRE is first and last an acoustic concept nor a gear engineeering concept...

Then buying a tube pre-amp to improve "colors" or "balance" between components is notenough for  solving the acoustic problem about tonal color perception from recording playback in YOUR ROOM for your ears... Buying a tube pre-amp is only good to improve the performance of your system but in the SAME room acoustic condition...Upgrading may be not always the solution...Acoustics rules nevermind the level and price of your system...This does not means that acoustic improvement will compensate for bad gear design , it means that gear design will NEVER replace acoustics defects ..

The acoustic definition of " color" is related to the definition of timbre experience which can be understood and must be understood in psycho-acoustic by at least 5 physical acoustic criteria which are influenced by simultaneously the room speakers relation and the gear components characteristics and also by psychological evaluative perception ( the state of emotions and the individual music journey ) ...

It is a complex matter pertaining not just to gear design quality but also to physical room acoustics in specific relation to specfic gear system design and to the psycho-acoustic conditions linked to timbre experience and evaluation which imply subjectivity and neurology...

In a sense the question of the OP is a road to misunderstanding by underestimating the complexities of the timbre experience, with the implicit presupposition that the gear will be the main factor...

The better question will be : how do we improve timbre experience ?

For sure i could  understand this question as a question not about fundamental acoustics but about the gear pieces...This is not wrong to ask this question about the synergy of gear pieces in one direction : warm, cold , neutral...My claim is that this question about gear colors  is not meaningless no , but it is misleading question which stay on the problem surface ...

I concur with your observation...

Because our own taste are grounded in our ears/brain neurological specifics among other factors and this is adressed in psycho-acoustics...

Then it is not only about the gear synergy and embeddings for sure...Our tastes reflect our history and neuro-biology of hearing ...

It's an evolutionary process ... not just in terms of how your equipment choices evolve, but also how you gradually learn what type of sound appeals to you the most. Honestly, when I started I had no clue what I liked. So it's not always about the synergy but also an exercise in self-exploration.

Very well said...

I think that a couple of you misunderstood what I said. I wasn't suggesting that certain speakers or electronics add timbre or texture. I was saying that the best ones expose the timbre and texture that actually exists in the recording. It's not an added coloration.

To the canonical factors associated with music , Edgar Choueiri the genius in acoustic, added the spatial factors , which now we can use in recording DSP and -playback system with his BACCH filters...

Canonical musical factors : pitch, timbre, texture, volume/ dynamics, attack/duration/decay, melody, rhythm, and form.

Spatial factors : Reverb; Envelopment; Depth & Proximity; Spatial Extent & Resolution; Motion; Spatial Modulation; and Spatial Segregation.

This speak about the sound and the soundfield relation to be way more than just about  what audiophiles speaking about gear called "colors"...

Acoustics is the key and the road in audio not the gear which is only the vehicle and tool ....

Acoustics is the sleeping princess, your ears/brain is the kissing prince and the gear components are the 7 working dwarves...

i prefer the  boobs of Marianne on Napoleon...

😊

Equalizer mechanical or electronic one are tools not the solution... i used the two types ...

As building a house ask for many tools used in some balance way and in some order, you must use many tools and tweaks to reach a specific balance ratio for each system/room which will not be nor colored nor neutral but will display his specific "hue" ...

Synergy between components is the first factor, to create an ideal balance ask for more work and for some tools and embeddings controls ...

if we dont have synergy to begin with the rest of work will not be easy and inj many cases even doable...No amount of equalization will replace synergy in many cases or a component which pair not well with another one...

if you dac is too harsh coupling it with an analytical amplifier sound will not result in an optimal balance even if equalization will decrease the harshness or the fatigue a bit...And if the room is to echoing or not set for this case it will be more disastrous..

Reaching balance is a complex problems in all working embeddings dimensions and begin with the right or wrong synergy... It is not easy to figure it out, it was not for me...

I think that speakers or electronics that portray timbre and texture well are perceived by the mind as "colorful."

Yes they are perceived as such because of the contrast with badly designed components which usually are harsh and analytical...

But in acoustics experience , timbre and texture are experienced optimally in BALANCED system/room with BALANCED and synergetical components...

Then we must wish FOR BALANCE not for colors...Even if a bit of unbalance may well serve and answer to some taste and even if perfect balance is not always the optimal possible  answer in particular case..

The problem is not the lack or the excess of colors...

It is only a symptom or a manifestation of unbalanced components synergy or the presence of a too harsh and bright component or of a too warm one...

The debate between colors and neutral is a red herring from the real problem which is synergy between components and acoustic embeddings...Most of the time it is reducible to these three factors : badly designed harsh or too warm component instead of more neutral component , synergy between more colored and less colored components and the right acoustics embeddings of them all...

Then que question to ask is not how to add color to a liveless harsh and fatiguing or too clinical system but how to create a balance and a synergy between the components/room...

We cannot and should not add color to a system , instead we must create a better synergy and balance between each components using electrical, mechanical and acoustical embeddings controls to the necessary synergy between dac and amp and speakers .....

To answer rightfully to a question implied that the question must be ask in the right way...

And remember that as much as upgrading a "defective" component is not the solution to the problem of balance between component by itself, (for example buying tubes components),  nor a solution for their optimal workings condition ; embeddings controls are the solution after the right created synergy is reach... And this is true with or without tube components or with or without analog or digital components... These debates between tubes and S.S. are BESIDE  the problem...And people often present upgrade or purchase as a solution, which is not and cannot be  by itself THE COMPLETE SOLUTION...
