How can DAC's have a SOUND SIGNATURE if they measure as transparent?

Nope. I never said anything like that.
Except...
I listen to some reviews based on listening impressions and personal opinions instead of purely science based facts.

Of course science is a very important part but I believe there's more to it. Did it ever happen to you, that a speaker measured perfectly flat but for some reason it didn't sound good to YOUR ears? Maybe a tube amp that didn't measure well but it sounded really good? I have.

Appearance has NOTHING to do with science, yet people generally do find a beautiful speaker more appealing and better sounding. Snake oil in plain view? Yea, maybe. Cheap parts inside and beautiful outside is rather deceptive. Buyer beware.

I believe there are three important evaluations to consider. #1. science. #2. how does it sound (subjectively) #3. how does it look. So, no I don't just use science as my only barometer. Guilty as charged.
It seems this post and its first sentence has been quoted back at you already. By now, surely even you must realise that you posted it? It was only 36 hours or so ago, you must have some idea...
 

... first sentence.

The accusation is attempting to say that I ONLY listen to others opinions and disregard science. That's NOT true and is not what I said or implied. Come on! In fact, just a few sentences later I mention science as #1 consideration.

My quote: "I believe there are three important evaluations to consider. #1. science" Why not mention that?

Sorry for the confusion. The accusation that I only listen to opinion and disregard science is completely false. Some REVIEWS I sometimes listen to are based on subjective opinions rather than science. Yes. that's true BUT this does NOT mean that's all I listen to and that I am disregarding science. Did you miss a few sentences later I said science is #1 evaluation to consider?

Yes, I did see that. However, if you also report things in the same post like

... then you don't seem to be putting science (as explained to you by others) at number 1. Now, that's fine for your personal preferences. But you do not seem to be getting the message that the "ears" thing is as likely to be about your perception as the actual sound waves in the room. As for a speaker measuring "perfectly flat", not only do I doubt "perfectly", but there are more aspects to the speaker than FR, as you can see from any reviews here, or the associated video on how to understand the measurements.

If you want to have science as your #1, don't you think you should learn the science you profess to use? Too many people here think that SINAD = science... there's more to it.

Nothing wrong with using the ears to evaluate but... use the proper techniques and controls. This is difficult and very time consuming and requires specialist gear so no one really does that. This means it is pretty safe to assume it is merely an opinion and should not be seen as facts.
Most of the 'more subjective' reviews simply lack that and for that reason will be dismissed by most ASR regulars.
That does not mean there can be some helpful things in those reviews.
The difficult part (for most readers/viewers) is how to correctly separate fact and fiction from the reviewer's vented opinion.
A good example is grandpa Paul ... and Hans Beekhuizen to name but two and forums like SBAF. Some facts and nonsense/opinions/whatever readers/viewers love to hear that fits their own view/findings all rolled into one.

Reading other people's opinions and subjective findings obtained in non controlled 'tests/comparisons' simply is not the way to go.
It is highly likely to be riddled with opinions/myths and biassed convictions rather than hard facts.

Sure, some of these reviews highlight 'feel of the volume control, switches and some usage aspects which might be helpful. The 'acoustic' properties that equipment might have (excluding transducers) is just silly talk.
That's what this back and forth is all about.
Your opinion simply is not considered a fact even though it is a fact/correct way for you.
 
Well hmm. Amir has done a lot of ear training (in the audio, if not music theory, sense). If he, for instance, said he walked in to an exhibition room at an audio show and thought the sound was inaccurate in some way, I would take that into account. The issue isn't whether people hear something so much as *why*. There are a million reasons one can like or dislike or take issue with sound. It could have been the room, the recording, something in the chain, some background noise.....or entirely in one's head. So I wouldn't jump to the conclusion that it was the equipment being advertised in that room.

The problem with the vast majority of subjective audio commentary in this industry is that it describes all sorts of sensations, but attributes them to specific equipment. Even when this is incredibly unlikely.

Here's one of the first things I googled:


In this article we go from highly subjective perceptions, very likely just the result of paying attention in a different way, straight to the allegedly revolutionary D/A processing. What I really object to is the reviewer making that trip without even a nod to other possible causes. But the industry demands it (with its advertising dollars). Such a mess.

"allegedly revolutionary D/A processing"

Well it should be if you paid $90.000 for a DAC (system) don't you think;)

Also say whether it is ........... revolutionary...
- complex
- sophisticated
- innovative
- over-developed
- unbelievable
- expensive
 
Late question and things may have moved on,, but are you sure it's not the amp/speaker issues/room causing fatigue with so-called'accurate' dacs?

I mean and apologies for going off on a tangent, I fullt 'get' what many audiophiles prefer about the different presentation of the vinyl format, but in my case it's from the opposite end, me trying to liven up and have more 'sparkle' from my vinyl rig rather than 'toning down' the digital (and somewhere between, my FM tuner) to match the slightly 'gentler' vinyl presentation.
No, everything else was kept the same...only the dac changed.

I don't deal with vinyl or tape, zero interest in such analog formats..digital only.

You know, this may be why many speaker designers prefer to put a slight recess in the lower kHz response, to aid what I can best describe as 'listening comfort.' I mean, our ears are hardly flat in receptivity and they change with perceived loudness as well, so a ruler-flat response speaker, wide directivity and played in a lively domestic environment may cause intense discomfort when reproducing a dynamic piece of music.

Just a hunch above, which may have nothing to do with your situation :)

Man, that's some high-level word/phrase craziness there.
 
Food for thoughts...

This is 1kHz @-6dBFS from an old Marantz CD4000:

And this is the same 1kHz @-6dBFS from an AH! Njoe Tjoeb 4000 CD player which is a clone of the Marantz with a tube output stage:

1727887637979.png


Tubes might need some attention (it will be done soon).

Now, fun fact, recording from the two players (at 24bits/48kHz) and playing back with Foobar ABX, a friend, my son and I failed to make a difference between the two (track was the same as the one used in the Klippel audio test).

Cheers

Using music that is not too surprising.
 
For decades 1% distortion was considered high fidelity based on early tests showing people could not distinguish distortion in music below that level. 1% is -40 dB. People claim 0.1% detection for pure sine waves (-60 dB), but last time I tried, that was pretty difficult in blind testing. It was years ago but I think I was just above the 50% correct level.
 
For anyone who thinks they are immune to confirmation bias, consider this:

Do you mean that the hospital staff are demonstrating confirmation bias because 'pseudopatients' pretended to have mental health symptoms and the hospitals admitted them? It's an interesting study, ethically as much as anything else, but I don't think its useful for us. Far too much to get lost in.

You may have missed when they reversed the experiment and *said* they were sending in fake patients but didn’t…and the institutions confidently identified the fakes.

It’s relevant because one of the common ideas in this thread is that the listeners are skilled and careful and can’t fool themselves. But highly skilled professionals do it readily.

Not sure why you felt it necessary to police the relevance of the experiment, but there it is.

Not 'policing' the relevance or anything else about the experiment. It's interesting and well documented.

Just saying that the complexities of diagnosing mental health disorders, while clearly open to confirmation bias errors as well as many other issues, cloud the picture. it would be easy for someone to get distracted by the complexities of the issues in that study and try to use them to disregard confirmation bias in audio. Or perhaps it wouldn't and that's just my view.

Listening to audio equipment is a much simpler affair, is absolutely affected by confirmation bias (and other biases) and it's strange how much resistance there is to accepting that. Not by you, no implication intended there.
