Oh, as I don't believe my 'ears' have nothing special or exceptional, i whould satisfy myself with *your* theresholds.
Please, can-you tell me the thereshold limit for HD (as a start) below which no gain in quality is expected. Samething for slew rate in a servo system (feedback loop).
Thanks in advance, you will save my (electronic) life.
You can choose your source material and manipulate it with standard software packages to put in whatever distortion you like, then find out what your threshold is. It's really not that hard to do.
I'm sure any competent neurologist could easily explain this. The rest of us will just have to assume that different bits of the brain are accidentally wired together where they should not be. I don't understand your point.Joe Rasmussen said:
I am amused by all the wriggling and squealing which goes on when someone is asked to show that something which he thinks he can hear is actually being heard. Curiously, when circuit theory tells us that a change is small, and known accepted psychoacoustics tells us that the change is probably too small to be heard, it usually turns out that people who can 'hear' it while peeking can't hear it when not peeking. They often attribute this to the stress or unreality of the test, yet something which psychoacoustics says should be heard usually can be heard without peeking in spite of all this stress.
You can count-me for one ;-)
I agree with what you said about listenings.
You're almost right. But we probably can measure it, the problem is we don't have an interpretation that represents relevance to us. Distortion figures only help if we look at the harmonics, for example. Even if the data is there, we don't really know squat about the subtle differences in it that will give us just music, and something exquisite.
Arteria carotis interna, runs through the openings in the cervical vertebrae, main highway for supply of blood to the eyes.
(narrowed disc space, herniated disc, age related wear. Music => head/neck movement)
Even completely healthy people can see flashes/colours, think stress etc.
Are-you Joking ?
Do -you mean that adding harmonics to a sinusoidal signal has any sens, and can allow to says "under 0.01% of HD, an amplifier is perfect" ?
Harmonic distortion and IM are constantly changing, depending of the constantly changing levels and frequencies of the musical signal.
I'm really sorry to inform-you that no amp sound exactly like an other on a given set of speakers. If they both measure <0.001% of distortion, a flat bandwidth from 10Hz to 100KHz, and a damping factor > 450, can-you explain-me how this is possible ?
And if you pretend there is no difference, i will see only 3 possible reasons for your claim:
1-You lie.
2-You are deaf.
3-You are dead, and you don't know-it.
Since you're attributing a bunch of things to me that I never said, I can't really respond to them.
But if you want to know what your distortion threshold is, you can use some software tools to determine this. It truly is not difficult.
Cristophe--again, it feels like you're tilting at windmills. You can be a perfectly honest person with decent ears and still attribute to hearing things that, when put to the test*, fall apart.
* Blinded comparison; pick a preferred protocol and perhaps ask/research whether or not your test will be remotely conclusive.

On the subject of colours, I generally don't see them, but invariably do when listening to my most favorite pieces of music. At such times, I often don't thuink about systems and electronics, I just listen and much more often than not, my foot starts tapping all on its own. Moments of bliss, so to speak.

That's because you're rocking the objectivists' boat, John. Doing your own Boston tea party here.
But you do need to take a bit of care when stating something big. For most of us to follow your reasoning, you sometimes would need to elaborate a bit, to make your key point more clearly, more in prespective, so to speak.
For example, when you state that the best of discrete beats the best of op amps, it would be clearer if you were to add just how that manifests itself, like cleaner and/or better sounding treble, or substantially deep and profound bass lines, even if the measurements don't show it. That sort of comment.
