I've found out that our community lacks sound science facts. I would like to fix this for the grea justice's sake. Sorry for not being a native english speaker. I may also "invent" words because I know three languages: Russian, Romanian and English. Latin words from Romanian I frequently mix with English, sorry again.
To understand my language (the way I express the thought) the easy way, see spoiler below, section 1.
Abbreviations in thread&posts:
ATM - At the moment.
AFAIK - As far as I know.
FAC - Frequencies' Amplitude Characteristics
Frequency response - a particularity of FAC
Reference Audio Analyzer 3.5 - The software which allows us to TEST anything regarding sound quality! (FAC&FR) [equipment needed] - A HUGE improvement to the www.personalaudio.ru PROOVES value.

Our reviewing specialists aren't really specialists. A specialist shall have knowledge of sound theory and science, which are hidden in physics. Specialists ATM [NO OFFENSE, i'm just being objective!] look like guys with a lot of money who just "unpack-test-feedback" to answer which product is better _in_every_perspective_. Yes, they do know what is good and what is wrong. But lack of money (reason why one doesn't know what is good sound quality) must not be a problem here at head-fi!! Using my knowledge and money I got a perfect 5.1 surround headset. Yes, outdated driver material, but the rest is perfect.
Basically, any equilazer is an AMP. We do not have an AMP only when getting even more dB (over 100% by using AMP/pre-AMP) we lack power supply and/or we reach audio chipset limitations.
Russian audiophiles community has a term named "Frequency-Amplitude characteristics" which gives a very funny idea when going deep into HF.
"Why shall we need the term "product sound signature" if we can make virtually anything sound perfectly using a good AMP?" [Note: impossible with a pre-amp.]
Virtually anything, because we may theoretically have a case where 15337 kHz is -40 dB, 15701 kHz is 55dB [that's called a frequency "spike"]. Very hard to understand and a very theoretical example, but I shall be objective when speaking of science, so forget the lack of realism. In such case we need an amplifier which equilazer might be customized for very tiny frequency ranges, but we ain't got such technologies ATM. I just mean the bigger are the product's "spikes" the better AMP is needed. Better isn't equal to power, because better AMP is a more detailed AMP. We have limitations in dB, which are the distortions, a trouble of the material - Neodymium (drivers' hi-end magnets AFAIK).
I mean sound signature is a science term, while at head-fi it's more like "consumer feedback".
You express your feelings about the sound got, but there is a need of science, for great justice.
Why do we use such terms as sibilance, soundstage, "bathroom effect", fuzzy/muddle?
I suppose, with your permission, that we don't need them at all, just because we DO use terms like "lack of treble", "for bassheads" and others and they fully refer to signal signature, but we can objectively say it's about frequencies.
When analyzing my own product: Cyber Snipa Sonar 5.1 using it's soundcard with an in-built AMP (equilazer) I really managed to get perfect sound (while doing that I've learned sound science things AND equipment testing principles (that_thread is poorly adapted for the audience (my language sucks within it) and I was driven by the same main idea (High-end isn't really high-end because of information lack) but I was focused on 5.1 headsets, i'll just refurbish that thread and start a Sound Science thread having Roccat Kave 5.1 as example instead of these : http://www.head-fi.org/t/689580/overview-review-request-cyber-snipa-sonar-5-1-gaming-headset ).
So, which answers did I get, while doing that:
1. I've proven to myself nothing is relative. ( A philosoper's thought of mine, we can discuss it PM if you wish
)
2. I shall destroy all the relative things here on head-fi.org because we shall see sound quality as a primary criteria, but we cannot do that without sound science. "Signature" is not sufficient.
3. I understood sound science, got it related to physics, which destroyed relative i've trusted (info from head-fi guys) things in my head.
4. Testing should be safe&systematic.

LOW_TREBLE - heavy_rockers get pleasure by listening to like ~95-115 dB of 2-12,5 kHz [PROVEN] link#2 below
LOW_VOCALS - same, 1800-6000 Hz. [PROVEN] link#2 below
LOW_BASS - same, 20-160 Hz, that's why you would better get a subwoofer and THAT'S WHY 5.1 (2.1) can REALLY make the difference for a bass-simpathyzing audiophile, even disregarding FLAC 5.1 possibilities! It's funny, but I got perfect sound, I suppose with 5.1 system, because 4 of 8 drivers are treble-dedicated, 2 are bass-dedicated and 2 are mix/central, so I adjusted bass to be louder than treble PRE-AMP, using _each_driver_loudness_, afterwards, I have done "tiny [/p]optimizations"by using their product's equilazer (it's not a normal equilazer, it uses percents of true max dB, while ordinary equilazers "presume they know" max dB and just cut 1 dB flat from any given loudness, so it's not "tiny" at all)
[PROVEN] link#2 below
LOW_SOUNDSTAGE - 120-640 Hz, the sound seems "flat" [PROVEN] link#2 below
SOUND_SIGNATURE_DISLIKE - If you listen a _proven_to_be_perfect_ product and it seems you "lack" something then it's a "tastes" issue. I've found out I LIKE ALL GENRES OF MUSIC, (except pop, lol) because I really got it how people get the pleasure from "tastes"
I_DUNNO_WHICH_FREQUENCY_I_LIKE_LISTEN_TO_THIS_SONG_PLS - try http://doctorhead.ru/images/misc/review/report-hp/fr-fr2.png locating your frequency by translating these terms into english, google translate should be ok for this
*shall be in-depthed with each genre's specific perfect sound signature, these are far from genres now, but you shall be able to get the point*

We have some very minor "Frequency-Amplitude Characteristics" (any certain frequency) deviations in high-end products. Using an low-end AMP with a high-end product is wrong, because we have the class high-end MONITOR headphones [WHICH MEANS any given frequency will dB-deviate just a bit] {also} [We have budget monitor headphones, I suppose i've heard about Superlux (a copy for audiotechnica, I presume)]. A high-end product is at least nearly FAC perfect, SO playing with the AMP will just give the sound your desired signature. Using a high-end amplifier can give you perfect FAC with ANY PRODUCT, bearing in mind some +20dB "fix" may cause driver failure. I've seen examples on russian forums where a high-end AMP got 200$ middle-signed headphone achieve PERFECT FAC! [ http://doctorhead.ru/images/misc/review/report-hp/rzp2.png example #1, http://personalaudio.ru/raa/otchety/naushniki/philips-em-2126/ example #2. I suppose they use a 0 resistance AMP, which is _literally_ golden].
Sound-to-noise is also a sound-signature related term. It tells us how construction (drivers' localization, materials, etc.) influences the sound from the dB perspective. I suppose humankind has already passed the frequency deviation.
Problem is, Sound-to-noise is given as "normal" like >50dB, usually. That means 50 dB of loudness may cause 1 dB of "noise". Is that objective? No. See next chapter.
We have the materials, the design crew, engineering crew, marketing and others. Point is that marketing and profit usually are MUCH HIGHER for "brands". Sennheiser, as example, sell some low-end headphones. These are cheap crap, literally.
The point is BRAND should speak about trust!
Brand_value [should be like] = SUM{for every product tested}[ (k*Perfect_sound_quality + n*comfort + m*perfect_build (at least good, but NOT resistant to force-major) ) ] / (total_products_tested/build_fail_products)
The accessories being a weak pro for a certain model.
[Note: taking this model of BRAND i cannot call my Sonar 5.1 high-end at all, because it has build_failure as any of it's copies, I'm planning on buying&analysing a real brand with humble price - Roccat Kave 5.1 {I would buy 2.1 for the subwoofers if I would not need 3D localization and 5.1 FLAC possiblities}]
In the priority order of k,n,m descending!
The k,n,m everyone chooses for himself, BUT value should be TIED to the overall Brand_value. If we have PRICE-"spikes" in brand table (values listed), that will mean someone is humbly/arrogantly pricing his products.
I am destroying the head-fi's famous expression, "sorry for your wallet".)))
We need to choose by sound signature ONLY if we use NO AMP AT ALL OR(!) we are choosing from the very low end (usually 3-40$).
I can prove everything I said, except I have no money to buy FAC analisys equipment for the case I need to speak about one product's sound signature and I can't find any info on russian forums.

I'm just trying to do what i'm usually doing in russian: Being as laconic as possible, without losing clarity. English (for me) gives me no such possibility, because either there enough words in english for that kind of clarity i'm used to or I do not English too well.
Ok it is complex sometimes. I can apply programming principles in thought expression. You know: algoritms, shortcuts, variables, optimization, etc.
Optimizations applied by priority, capped by English knowledge: Pedagogically accessibility (to really understand the math behind), expression clarity (to exclude any two-way understandings), laconicity (style&spoilers&expressions' polishing)

MygpuK said:It's a philosophy question, so the answer will be in much volume, but instead I will gain some more respect in your eyes, I suppose.
A person has some principles. By principles I mean RULES. My essential rules are: Truth&Justice. Justice is not always true, like the situation with high-end localization for the community. It's Justice, because head-fi did the analising part, but it ain't Truth, because these analisys where somewhat wrong, because the reviewers had no objective info sources.
I'm the source transmitter from the RU community. You may spit may face and call me jerk as you wish, I won't aggro. I appreciate and defend my ego, where it comes to feelings but I do not respect it, by ego I mean emotions. Emotions shall be personal, if you consider yourself a man, yet you make fake some emotions without lying to get to your objectives. That's called being smartBecause egoism is something which is simply ok in society nowadays. I'm trying to fix that - writing a metaphysics book (true philosophy, before me there was only 1 metaphysic - Aristotel).
I'm driven by my principles, as is any of us. I'm just not paying any attention to negative emotions. Lack of self-respect may be an issue because of which I would like to promote myself. I have no such lack, trust me

Explanation
Why do we use such terms as sibilance, soundstage, "bathroom effect", fuzzy/muddle?
I suppose, with your permission, that we don't need them at all, just because we DO use terms like "lack of treble", "for bassheads" and others and they fully refer to signal signature, but we can objectively say it's about frequencies.
It's all about frequencies
When analyzing my own product: Cyber Snipa Sonar 5.1 using it's soundcard with an in-built AMP (equilazer) I really managed to get perfect sound (while doing that I've learned sound science things AND equipment testing principles (that_thread is poorly adapted for the audience (my language sucks within it) and I was driven by the same main idea (High-end isn't really high-end because of information lack) but I was focused on 5.1 headsets, i'll just refurbish that thread and start a Sound Science thread having Roccat Kave 5.1 as example instead of these : http://www.head-fi.org/t/689580/overview-review-request-cyber-snipa-sonar-5-1-gaming-headset ).
Trouble is I damaged my bass drivers (one of them was resonating on the in-built mic, got nearly broken, ATM set at -25 dB, and my treble settings are at -0... You can imagine the sound with the bass 25 dB lower than needed, while "ready_to_go" it lacked bass, that's why I started customizing... At the end, I understood a need to study a relative (ATM) thing: my bass satisfaction is capped way out of 96 dB, that's why this particular bass driver could not satisfy my needs (the drivers are capped at 108 dB (not Neodymium), but the product's engineers did a build design mistake - the mic's inner parts get smashed by the bass driver at higher than 96 dB volume...
So, which answers did I get, while doing that:
1. I've proven to myself nothing is relative. ( A philosoper's thought of mine, we can discuss it PM if you wish
)2. I shall destroy all the relative things here on head-fi.org because we shall see sound quality as a primary criteria, but we cannot do that without sound science. "Signature" is not sufficient.
Here on Head-fi we are supposed to have democracy. Everyone is equal, even the one with no money to afford something good_in_every_perspective.
3. I understood sound science, got it related to physics, which destroyed relative i've trusted (info from head-fi guys) things in my head.
4. Testing should be safe&systematic.
MYTHBUSTING
Update #3:
Oficially DESTROYED sound myths are
SOUNDSTAGE, CLARITY(detail), SOUND_SIGNATURE sibilance and
underwater/bathroom/muddle/fuzzy effects. The questions may reapper only if we proove www.personalaudio.ru non-objective which I highly, HIGHLY, EXTRA-HIGHLY doubt.Sibilance - driver limitations in some treble frequency range are "broken". Found by myself sibilance can be heard at 4 to 8 kHz. [PROVEN] Update: 4-9 kHz (RU theory, untested, but proven by it).
Underwater/bathroom/muddle/fuzzy/etc effect - some frequencies are giving "ambience" effect. I've found out their localized at 175-500 Hz. See soundstage vs clarity/detail for in-depth [PROVEN] (RU theory, untested, but proven by it).
Soundstage - also an effect. You have stereo, how do you suppose a round driver can give you 3-dimensional localization? Brain is complex. You just have the feeling the sound is not flat. We should see lack of soundstage as a lack of certain frequency loudness. (i've nearly localized it ATM) Yes, it's strange, so are our brains.
Update: RU theory saiz it's localized in between 250 and 450 Hz, in somewhat that range i've seen flatness of the sound. [PROVEN]
Update: Soundstage frequencies are the base for TRANCE music, they give psychodelic effect, AFAI've felt.
Update: Soundstage frequencies may also create some sort of "distortion" [brain percepteiveness issue] to other frequencies when they are louder than they should be.
Soundstage vs clarity/detail - Either detail is a dB frequency response issue (easily fixed with a good enough AMP - reavealed in upcoming PERFECT PORTABLE COMBO thread) OR it's supposed to be an frequency deviation which can't be truth, because true high-end headphones cannot deviate frequency - it's done be physical limitations upgrade already - Neodymium, dB I've felt is related to diaphragm size (50mm) which came from ru.wikipedia.org analisys http://ru.wikipedia.org/wiki/RUSSIAN .
Soundstage vs clarity/detail [abordage] - Soundstage is IMMENSE when you volume cap 250-450 Hz (cap=louder damages the product) frequencies, but there is a downhand - "muddle/fuzzy" - GOTCHA! I've tried to downcap (literally, to zero) these frequencies, as a result - "flat" sound. It's like 1d instead of 3d (there are no sound direction for stereo, although, it's only an effect).
[PROVED BY ME, EASILY FACTED-OUT] by a guy with true(and not) high-end stereo & a very High-end (by technical specs!) amplifier with high resistance ]
Sound signature - there is no sound signature as a term of sound quality. We are allowed to speak about sound quality fail when we have any of the before effects present in a good_to_go product [No amp/equilazer]. If you're going to use a high-end AMP/equilazer, pay more attention to max dB [AFAIK max amplitude i've seen on portables may be achieved using 50 mm drivers for stereo, but I assure you, there are 5.1 products better and less arrogantly-priced that will fully satisfy you].
Update#2:
Sound quality - whether IS IT possible to fix the dB deviation issues with a medium AMP (in-built for a PC/mobile_phone soundcard). It is not possible usually to get perfect sound up to 0.1 dB deviation, because technologies did not give us SUCH amplifiers AFAIK, ALSO it is neither possible to "fix" such a product because the manufacturer sets the maximum volume, usually, just because amplfying will result in distortions (not true for true high-end), so by "fixing" you will lower overall volume to avoid effects given above.
Underwater/bathroom/muddle/fuzzy/etc effect - some frequencies are giving "ambience" effect. I've found out their localized at 175-500 Hz. See soundstage vs clarity/detail for in-depth [PROVEN] (RU theory, untested, but proven by it).

What sound signature really is
We have some very minor "Frequency-Amplitude Characteristics" (any certain frequency) deviations in high-end products.

The dilemma revealed from the manufacturer's point of view:
I've seen head-fi thinks like "expensive=high-end". Now we should think how price tag is put on a product.
We have the materials, the design crew, engineering crew, marketing and others. Point is that marketing and profit usually are MUCH HIGHER for "brands". Sennheiser, as example, sell some low-end headphones. These are cheap crap, literally.
The point is BRAND should speak about trust!

The accessories being a weak pro for a certain model.
[Note: taking this model of BRAND i cannot call my Sonar 5.1 high-end at all, because it has build_failure as any of it's copies, I'm planning on buying&analysing a real brand with humble price - Roccat Kave 5.1 {I would buy 2.1 for the subwoofers if I would not need 3D localization and 5.1 FLAC possiblities}]
In the priority order of k,n,m descending!
The k,n,m everyone chooses for himself, BUT value should be TIED to the overall Brand_value. If we have PRICE-"spikes" in brand table (values listed), that will mean someone is humbly/arrogantly pricing his products.
I am destroying the head-fi's famous expression, "sorry for your wallet".)))
We need to choose by sound signature ONLY if we use NO AMP AT ALL OR(!) we are choosing from the very low end (usually 3-40$).
I can prove everything I said, except I have no money to buy FAC analisys equipment for the case I need to speak about one product's sound signature and I can't find any info on russian forums.

The lower I've found too hard to translate at least most part, so it will wait a bit.
The lower part is "decriptions for the frequencies", meaning not the instrument, but the subjective association.

P.S.: Pre-amps have absolutely no clue unless the engi crew has supposed the product will be used with an amp (driver supporting more than the max amplitude, lol).
