I’m going to disagree......I just bought a higher end integrated that sounded so slow I thought the motor drive on my CD player was going out. (It was not)
The piece in question was under warranty so after trying my best to dial it in without success I sent it to the nearest authorized service center where everything checked out to spec.
I have no such slowness from my prior amp (still in use) same sources,same everything just different integrated.
My research into what can cause a slow sounding amp mentions slew rate as a likely culprit....something to do with rounding of leading/trailing edge transients.
I don’t know this for sure but I do know the pace rhythm and timing on this piece is screwed up.
When we cannot pass an ABX but feel that is a difference is not an indication of fact either.
You sure do post often like those who are in audio business. You may not be in one now thus your claim that you are not in it but perhaps you will be starting one soon, kind of like Mark.
That's what I was trying to say (and more). I was also saying that when I insisted and succeeded in the ABX then the feeling became a fact. If/had I stopped it was become just a feeling (like my feeling that Vishay-Draloric SMA0207 sounds terrible).
Isn't it naturally humanly logical? We try to materialize our skill and knowledge (and hobby sometimes). My friends told me that I'm a man who can do a lot of things, why I don't do this or this or that. Point: I have options.
I think you may be blinded by your 'hate' for the charlatans. The problem is not in the views but in the character. You don't have to be a businessman to be a 'charlatan'.
If I post about audio like those in audio business, that's because I share the same views with them.
this is starting to sound grainy!
at least, can we agree that grainy sound is the start of noise...
noise can be heard as noise in the music, grainy would be the start of noise, the beginning of hearing the noise.
So this points to the power supply as well as the noise floor in a dynamic proportion to the signal.

I'll follow this definition
because it gives attributes stolen from the musical language, and applies it to a ...machine.
Better to start from music. Music itself steals the time, puts a pace, creates and manipulates rhythm. The so-called goose-bumps are not caused by the high volume but come from inside the brain that controls the vascular system, adiabatic style with frowning ( if it sounds grainy) or tears, when it's-so-natural! Also sweat, lots of sweat for arriving to the goal
So goose-bumps are stopped by grainy sound.
Indeed, a grain, like a grain of dust in the micro groove that encounters the stylus of the pick-up at moderate velocity, it steals the information ( it provokes also a Toc that masks) and makes the stylus lose time in following the abnormal contour. I mean- a grain!
For a complete goose-bumps theory formation, we should consider the sebaceous cells and the hair, for completeness.
No. I think everything have already been mentioned/covered in the beginning of several few posts. There are things that I consider 'macro' (something that is too obvious to the ears) and things that I consider 'micro' (not obvious for most ears).
That's too 'macro'. At micro level noise is not perceived as noise. Details of the music signal can be 'buried' under noise (the noise HF signal is riding on the music signal) and so the effect of the noise is in the lack of transparency of the music itself.
The noise in the power line is very gross (It is almost as gross as amplifiers that produce hum). It should be filtered by power supply and the PSRR and CMRR of the amplifier circuit. At micro level (as in SNR), this noise is very low that even measurement equipment have problems to measure it (they amplify the noise but not the musical signal).
If there is such a thing as prat, it's easy to prove it exists. See my previous post.
With all things we perceive, there is the possibility of self deception. Truly honest people acknowledge that. In fact, if you do a little study in human perception, the possibility of self deception is staggeringly high.
Like I said, you must have experience in an alternate ABX universe where the terms and procedures are not same as this universe where the forum called DIYAudio exists.
Perhaps you feel that there are blindness and 'hate' going on here.
I wonder why you would share the same view.
Possibly because you are unable to filter audio facts from audio fiction.

I'm sorry for using difference language as yours. My knowledge is from hands-on experiences, not from citing others.
I put 'hate' in quote. Blindness means that you may not be open minded enough to see that those certain views are actually real phenomena.
I think it is because some people have more sensitive hearing than others. When they don't have electronics knowledge, in an effort to understand the phenomena, they make things up. I think hearing sensitivity is a trait that you bring from birth and more or less you can't change. Something like intelligence. But electronics knowledge is something that you can learn and improve. I don't share every views of the 'audiophiles'. Imho, I can see what the subjectivists see and I can see what the objectivists see. If you think of the story of the seven blind men, I'm not blind.I wonder why you would share the same view.
You can see objectivists are trying hard to find answers for some audio phenomenon. The biggest issue is they had to borrow subjectivists ears. If they had their own ears, they will know precisely where to go. In BT thread, you can see that JC is capable of observing some of these 'phenomena' but he is honest in saying that he doesn't know why and how. If you ask me whether I know or not, well, I have developed a method to put my 'hearing knowledge', a result of correlating perceptions with numbers, into a circuit that I applied to my amps. Validated in a way that I know it is not a feeling but a fact.
Will I be in audio business to capitalize for this? I don't know. I don't think so.

I think never. Friends told me: you have to give out first then everything will come to you automatically. No, thanks. You know the story.
From my previous post it should be clear that it is not something that can be easily taught. It's a talent. It is more promising if those subjectivist (like Bob) start to learn electronics. But this is the most difficult subject from all other engineering disciplines.
Bob and Pico were correct. Start from music. What do you 'see'/hear in it. PRAT, what is it, why can it be changed, etc.
I'm honest. That's the truth. It's true that you don't get benefit from doing nothing but it hurts when someone take advantage of your brain for his own success.
Perhaps it could be a gradual learning. You can start by learning how to play a musical instrument. Once good enough practice in a group. Join a band, choir, orchestra, something music related like that or simply sit with them during practices. You will acquire perceptive listening to produce good music as a group effort if you have it.
But I need to remind of the caveat, not everybody has it.

Man, you REALLY outta write for one o' them AUDIOPHOOL companies selling snake oil. That's the best rambling of total ******** I've heard in a long time!!
I'm going to make an argument from authority, so it's worth diddly squat.
I am a professional musician, for over 30 years. I can play bass, percussion, synthesizer and have my own recording and music production studio that other professionals use for their music. To those people I have proven to have a pretty good ear. If my old ears can't detect stuff, there are much younger people working in my studio that can.
Tell us what to listen for, so we can verify your "facts".
