The point was no one argues numbers.yet here arguing numbers. What is .5 children? Identify the couple with 2.5 children. That's the issue.
Frequency response is everything!?...

Amir,
I just discovered that you're a high-end cable dealer in Iran. Looks like the Skogrand Stravinsky cables that you sell run around $28K for 2 meters! I have to say that that does put your claim that you hear improvements in high-end cables into doubt since you have a strong financial motivation to promote that claim, whether it's true or not. Folks in your position really should disclose that fact in your signature block.
WBF is surely international
Were discussing measurable freq responses , lets keep the discussion " scientific " and keep cables ( pseudo science ) out of the discussion.
Good cable sound in general starts at around 50 K / meter
Cables certainly make a difference. Mine were very carefully selected for my system based on sound. The interesting thing is that they are industrial wires and not high-end audio file cables. A few of them are no longer made and they are all inexpensive. In fact my dealer just gave them to me when I bought the rest of the equipment.
This hobby is called HIFI not MY FY or YOUR FY.
If a artist / recording engineer tries to keep the signal within plus minus 2 db , the rest of the HIFI system should at least respect that
You probably had expensive colouring cables before , then DDK gave you good quality industrial cables .
IOW you went from pseudo back to real science

Frequency response discussed at kindegarden level is just pseudo science.
That is right. And if I had learned this from David earlier, I would’ve saved a lot of money and time. Even with these cheap wires, there are significant differences. Wires matter. The point is, you don’t have to spend a lot on audio file wires and they do make a difference.

There is nothing holy about what artists and recording engineers commit to the recording. These are the same people who instigated the loudness wars and dynamic range compression. Why should I respect that? If I am not happy with the way a recording sounds, there are ways to do something about it.

Please feel free to educate us on the subject and bring us to the next level .... primary school

Indeed. While I don't have DSP, my preamp does have an excellent analog tone control. I very rarely use it, and even most rock recordings sound fine in bypass mode (classical and jazz usually do so anyway). But the tone control is just what the doctor ordered when it comes to giving a few anemic sounding rock records some kick. I am not a purist about it. It's not my fault when the sound engineer sits drunk at the mixing board or the mastering engineer has a hangover.
Ron, I will bow to the many experts here but I think the answer to your question is the varying sensitivity our ears have across 20Hz to 20K hz frequency range.. Better know as the Fletcher-Munson curves or equal loudness contours. Basically, our ears are much less sensitive to bass and sub bass than they are to midrange.

I m currently designing small cheap loudspeakers ( cheap housing ) , but the FR target curve will be the same around 3 db on average down slope ( +- 2,5 db tolerance )

Luckily its very quit at my job at the moment so i have time for a bit of copy/ paste .
I found arguably the most well known mastering engineer for you , who even Quotes F Toole , what more could one want .
The MTP Interview: Bob Ludwig of Gateway Mastering

Bob Ludwig: No it isn’t. Dr. Floyd Toole worked for Harman International (JBL speakers) and showed that averaging all the different consumer speakers (some bright, some with too much bass or midrange etc.) one ends up with a very flat curve which is empirical proof that mastering with an extremely accurate and flat playback system yields a product that sounds correct on more systems. Like speakers, earbuds run the gamut from the old stock Apple earbuds that sounded tinny and lacking warmth to top-of-the-line Shure earbuds that are extremely accurate, to “hip-hop” earbuds that are overly bass heavy. One must master to sound as good as possible on all
Which is why a FLAT ‘weighting’ should not be used when using your frequency response app but A weighting which adjusts for our hearing response as pointed out here.Ron, I will bow to the many experts here but I think the answer to your question is the varying sensitivity our ears have across 20Hz to 20K hz frequency range..

Glad to see that you are slowly coming around, your audio knowledge has just been upgraded with the Nth degree
You are actually right, there is also phase, THD, IMD, S/N ratio, off-axis FR and then some.
This has been well understood for 50 years or so, but let me have the honor of explaining it to you. If you have a flat measuring speaker in an anechoic room and put it in a normal living room, you will get the tilted response, pretty simple.
The norm is a 1 dB/octave, so 0 dB at 20 hz and -10 dB at 20 KHz. You have around 3 dB/oct. to 10 kHz, seems a bit heavy loaded in the bass.
I see comments like this in here a lot, just in different writing. Nobody who works seriously with audio, says that the listener is not important. There has been written heavily important books, about how we interpret sound. I would allow myself to say that we have come pretty far on this subject. So when a lot of people on this forum, claims that the objectivist are only looking at graphs, the at least give us an example of such a person. Otherwise it is just strawman argumentation, that only serves to confuse and ridicule those who (also) have a serious approach.
