That's not a fact. IIUC, it is a theory invented by Amir. So far as I know it does not exist in any AES or similar scientific publication.
Moreover so far as I know Amir has not conducted publication quality, replicable controlled listening tests of many different dacs to provide "actual evidence" in support of his theory. Such a study, in order to be taken as credible, should also be compliant with ITU recommendations: https://www.itu.int/dms_pubrec/itu-r/rec/bs/R-REC-BS.1116-3-201502-I!!PDF-E.pdf
BTW, The Absolute Limit of Human Hearing is another threshold value. It only applies to single tones. Complex tones (multiple frequencies played at once) are not covered by that metric.

Oh AI god, which DAC sounds better?
AI: there are numerous available fom ESS, AK, Cirus Logic, Realtec (being the leader manufacturer of DAC chip sets world wide) and countless others as well as different model numbers, it is a personal taste of what sounds best to the consumer.
Oh cr@p now what do we do, we are all right and wrong
😒

Miller-8 said: The fact remains the limit of human hearing comes well before the distortion levels in the DAC output signals. so they should all sound the same.
Which human, me, you, anybody. If you have the best hearing then probably you call the shots. Like in the land of the blind, one eye is king. Nobody can argue with Amir, he has a measurement device nobody else can afford, so he must be right in every respect.
These things are so subjective it is not even worth discussing but we still do. The OP should be shot for starting this thread.

There is a range for humans, obviously. But the best human is well short of hearing the distortion levels we are talking about.
In the context of the discussion on doppler shift, if doppler effect of an approaching sound source changes pitch as it approaches, it means the sound source is not coming directly at you. Instead its going pass by to the side. In that case there is a changing vector component of its velocity relative to you that accounts for changing pitch.
I will assure you, it came right at me, and the angle was perpendicular. Maybe it was my eyes that are bad, not my ears?
😱😱😱
😱😱😱
Lets drop this nonsense conversation and stick to the stuff of which DAC sounds best. We can take the Döppler affect to the lounge. I need a fresh beer anyway.
Which side, be clear. Which side must I be facing to hear this. If it hit me and I was dead, what would I have subjectively heard.
It may become a bit of a problem if the not all posses the expertise knowledge to fully engage in a more advanced discussion...

I guess everyone for himself. You can place your DAC on acoustically inert bars of soap so you can listen to, and enjoy your phase noise. Or place your speakers in your pool and speed up the sound and roll bass off. Whatever floats your boat.
Lets get back to the thread guys. I am keen to know what and how members react to the sound of a particular DAC whether it is stand alone or part of a transport or streamer. What makes for a different sound (if any) is it the paraphernalia hung around it, surely the DAC as a components will have some sound signature like different transistor, Mosfets and the like as it contains thousands of them.

This isn’t merely a question of sensory acuity, it’s also a question psychoacoustic perception of the dynamic reproduction of music. The limits of hearing acuity should dictate that we all should rationally aspire to nothing more than an A/V receiver as the center of our music systems. Is the center of your system an A/V receiver? If not, why not?
As far as the analog outputs conveying all relevant information about what’s going on inside a DAC, of course. It would be illogical to suggest otherwise, but that also misses the point. The point is, whether you are assigning proper psychoacoustic significance to the correlated digital behavior (not just jitter) that appears to be a component of the DAC’s complex noise floor, as seen on spectrum analyzer? Stochastic noise isn’t the concern, dynamic, correlated noise which doesn’t appear to be correlated via a spectrum analyzer display, is the concern. For illustration, the effect on the sound of quantizer settling-time slew-limiting.
Maybe it is complicated, maybe it isn't... but for sure, it requires a lot of knowledge to answer this question ;-) everything else is guessing.... a now I'm going to be really blunt - I don't think you qualify. But your guess could still be correct.

No, no you won't. Altering quotes is against forum rules. If it happens again, action will be taken.
I am with your theory, there are many things inside the DAC that WILL affect its sound but I want to throw in another hook. It depends what you are listening too. I would never listen to a solo violin player, I listen to 70s/80s hard rock. I don't think you would see and discriminate this from noise on any spectrum analyser, ever. But as I said before the Topping and Wadia each have a flavour even on the same transport. Which do I like best. The older piece of equipment, why maybe I am not so much in tune with the highly resolving modern DAC with the music I like.
If you would ask me whether I prefer LP to CD I would choose CD, simply because I am over the rituals of carefully removing a record from its sleeve, wiping it with a special sponge, spraying some stuff, have a little brush removing crud from the stylus, checking tracking force, platter speed lowering the stylus on a specific track and everything else that goes with it.
