AES Paper Digest: Do Audio Op-amps Sound Different?

Critical(analytical) is the antithesis of emotional. Emotional enjoyment is more the norm. Psychopaths would be an exception but there must be degrees of variance out there.

 

TBH I think the bolded sentence is largely a myth. I have read studies from psychology which show that people with critical thinking skills have higher scores than others on emotionality, empaty etc... Maybe I can cough it up later. But now I really need to get back to work and stop talking on ASR!

 

I would like to see them. In my experience people who limit their range and depth of thinking tend to live socially easier lives.

Enjoyment is often confused with rewarding and satisfying. The last two terms are expectation conformational.

 

Interesting. My new tablet rejected it an unknown format fiile, but my desktop is happy with it and so am I. The unredacted version as it were. Thanks!

Have you read https://www.audiosciencereview.com/...-amps-sound-different.2625/page-3#post-75191?

The item of interest is "Average RMS Power".

 

The post above seems to have changed the question.

From its wording the apparent intent of the bolded text was to describe the consequences of a certain activity. but not necessarily to comment on the thinking power of the person performing the activity.

When I listen critically for technical artifacts. I very often briefly lose track of what the music sounds like or even what it is. IME Listening for pleasure and listening for subtle technical artifacts can be mutually exclusive at a point in time, but they can still be practiced independently.

It is all about using the right tool for the task at hand!

 

I'd bet that most non-audiophiles have never thought of listening for pleasure as a "task"...

 

I tried once. But nobody wanted to talk about Modern Talking.

 

I find listening for pleasure and listening diagnostically equally pleasurable. I generally enjoy life!

 

But that isn´t related to the Op-Study we were talking about or am i missing the point?

 

With AI, we might be able to train our instruments and turn them into humans...

One day when your new 2025 AP system 'AI Extreme' speaks to you and says 'Sorry Amir, you simply cannot hear, letalone measure what I can. I think I need a new human operator'

The machines are coming...

 

The relationship is via a post on the thread about a DBT that triggered speculation about the cause of positive results.

 

Separated activities? - except for the mental crosstalk. Once aware of other influences can you block their subliminal intrusion?

What influence does 'enjoyment of life' in general have to do specifically with the applied analytical discernment/discrimination or enjoyment of a particular activity.

General questions prompted by the post.

 

Sorry to barge in like this at such a late state, but isn't there a circuit error in the very first diagram in the very first post??

Whatever it is, I believe the shcematic on this forum is a good rendition of the cited AES paper. The other relevant authority may be the thesis that is cited later on in the thread. But I agree, I've long questioned whether it would work. Seems like lines are missing or drawn wrong.

 

Actually, reading the paper again, I think they DID have it correct. That 1st stage is NOT a 40dB signal gain stage, but that particular configuration increases the error (distortion) by 40dB. I will delete my previous post.

Yep, it´s just an implementation of the trick that was introduced to enable THD measurements well below -100 dBr; signal isn´t amplified, distortion is.

 

So what is the considered opinion here of this test? Are the results relevant to our perception of audio quality?
In the 'Discussions' paragraph, the authors concede that the opamps were forced to work with much higher distortion than in normal operational circumstances (+40dB, 100x as much).
But that's as far as they got, except for 'The assumption is...', '.. it is possible...', ' ...consider the possibility..'. Sounds not very convincing, but maybe I am missing something.

Hi Jan, welcome here. I thought the test was rather amateurish myself. Sort of seventies era stuff when integrated circuit op amps were new guys on the block.

 

A simple learning exercise in test methodology and paper presentation, I feel.
