Good plan.
Is positive reinforcement why things are sounding better?
So I buy a nice amplifier and later I buy a nice preamplifier and then later I buy Nice speaker cables and each time things seem to improve nicely.
And then I buy telefunken 12ax7 nos tubes for a tube amplifier, and improved tonality, clarity and a tighter sound is what I get and it's very engaging (tubes are only a few days old). The cymbals seem to come through with more openness.
Things seem to be sounding pretty good and I'm saying to myself is it real or is it just positive reinforcement playing with my head? And the devil is telling me oh let's buy more NOS tubes for the rest of the amplifier. The effects of positive reinforcement can be very expensive.
Just curious if positive reinforcement experiences have occurred for others, and how can you really tell?

Don't worry. I have enough to do in life than quibble on the internet. Those who know how to understand English will take my meaning and either agree or disagree, coherently. I just ignore those (bots?) who make random, semi-literate grunts. Saves my time. |
Remember it's a hobby. Don't spend more than you can afford or money you will regret spending. I've made many "upgrades" over the years. I would say 70% have been an improvements and the other "upgrades" I have sold over time. I often buy used and when I resell and consider my cost often and the entertainment I've gotten, it's in range of hobby expense. I'm a liitle surprised about one thing: when i upgraded an amp recently I gained bass control, elimated fatigue and etchiness and gained bottomless reserve. I lost some imaging and defintely speed and quickness. For me some upgrades have just been clearly superior, but as I've gotten better equipment the upgrading has usually resulted in more nuanced improvements. |
Acoustics parameters must be improved all together and put in balance for a specific ears/brain... If we dont learn about all acoustics aspects of sound it is easier to loose sight of one... But sometimes we forget this because of our focus bias pick one thing that matter for us and let the other aspect aside :

I have alluded to this in previous posts, but will restate it here. There is a profession called Sensory Science, which deals with the problem of designing products with particular intended sensory qualities. Examples are food, beverage, and cosmetic industries. Researchers in these areas have found it necessary to differentiate between two types of subjective experience. One is the literal experience of the physical properties of products. Interestingly, those in this field have found it necessary to use trained experts for the purpose with proven levels of sensory discriminability and repeatability. The average person is not very good at this. However, these people only serve as biological test instruments for the purpose of describing the physical qualities of products. They do not render qualitative judgements about the products being evaluated. The other type of experience is qualitative and is limited to such generic attributes as "liking" or "preference". Such judgements are provided by a sample of consumers who are like those for whom the product is intended. These people lack the sensitivity and reliability to describe physical details of products, so they aren't trusted for that. In the end, the descriptive data provided by "experts" are correlated with "liking" data provided by intended consumers and the physical qualities that are most correlated with liking are chosen as design criteria for manufacture. Those in the sensory industries have found this method to be the most reliable way to produce products of consistently good quality. My sense is that most audiophiles consider themselves to be good at describing the physical qualities of audio systems. That might be true, but in reality it is a pretty unique skill. However, most people can easily judge whether or like something or not. My point is simply that deciding whether you like a system is a good place to start. Figuring out why you like it, or what to change, is a secondary question and you might need help with that. |
When I bought my first tube preamp, a ARC SP-3a in 79(?) I bought maybe six different sets of tubes for it. Each had its own sound and I settled on the a Amperex 12ax7. Now I have an SP 9-MK ll that uses 6dj8’s and I basically did the same thing and ended up using Amperex 6922’s in it. Half the fun of this hobby is trying new things and seeing what hat they do, good or bad. All the best. |
@tonywinga , I don't think anyone is trying to say that all percieved sonic improvements are a result of confirmation bias. |
But I didn‘t know Wilson speakers existed until I heard a pair. I had no expectation bias but once I heard them I wanted a pair. It took me 27 years to finally work up the nerve to spend that much on a pair of speakers. And over that period of time I never found another speaker that I liked better- or liked enough to buy in place of the speaker I wanted. I agree that once I decided to buy my speakers, expectation bias continues to urge me to upgrade to one of their more expensive models. But that is counterbalanced by, 1) Lack of desire to actually change speakers- a lot of effort, time and money, 2) Spending priorities such as needing to eat, and 3) Risk of disappointment that a change will not meet expectations. |
Not if for the dungeon room?
Expectation bias is a root for favoring name brands, and confirmation bias can be an important subset of it. My impression has been it’s easy and reasonable to like something that sounds good to you, and it’s also easy but potentially unreasonable for that to morph into anticipation of more-More-MORE goodness from similar-but-maybe-better alternatives. Bias be aware, bias - beware.

How do you call your postings in a serious thread about an information important for all of us ? I get it! You were not sarcastic no, if i judge by your understanding of the concept of confirmation bias, you certainly cannot understand the articles about acoustic revolution in the making, no, you really think that i must go to an asylum for nuts ... Then you were merely harassing a fool with no sarcasm intended... Just the fun of it... I get it... Enjoy the evening... 😊

All people participating in good faith are invited "de facto" to any thread...For sure...This is a common place acepted fact .. Save trolls viruses who harass someone and did not contribute in any way with positive content and argument to the thread...As you did...they are not welcome by anybody ... Anybody can verify what i said about your behaviour consulting the thread last 2 pages "the mystery of sound is mysticism"...😊 They will see your "contribution" ... Not ashamed? 😊
You are so confused here :
I will not even answer. It seems you are unable to read any scientific article or even a wikipedia page about a concept as clearly defined ..

@mahgister , alluding to that particular thread: Audiogon Management sent me my invitation via certified mail; they did not provide a list of everyone else who they invited, so if the invitation you received was in the same format as mine was, you would not have known that I was also on the list. And you are mistaken; the only two (quite short) posts that I made as I was following that debacle were not intended to be the least bit sarcastic--I was serious. To the topic of this thread: confirmation bias, as it relates to audio, involves telling one’s self that one is hearing something that one is not actually hearing. Basically lying to one’s self.

I feel like I’m caught in the middle of something here. Maybe I’m biased but I like the sound of Wilson speakers over other brands. I confirmed that by listening to other brands. Therefore, I bought Wilson speakers. Would it not be illogical to buy a speaker that I did not like to hear? Or does confirmation bias drive me to upgrade to more expensive Wilson speakers? I do feel that urge from time to time. “If a little is good, then a lot is better.” I don’t know who said that but it should not be words to live by. Although it is difficult to avoid in practice. |
Great example! Me too with my children !😊 It is not a lie, it is the result of confirmation biases from their birth till now, all normal parent felt in a rightfull manner for his children... The fact that it can blind us and makes us unable of a wise judgement is another matter ... And a biased judgement must not be confused with a lie ... We cannot perceive without biases... Biases are not only negative they can be positive , innate or acquired... They can result also from a rational thinking process as in the abductive reasonning ...

Do you know the difference between a "rambling diatribes" and an argument conceptually detailed ? read my post above they clarify the simplistic claim of hilde45 about confirmation biases and the true definition with two different sources... Then you claim to avoid me, OK, do you avoid rational argument too answering a simplistic claim ? Do not lie, you DO NOT AVOID ME, you came uninvited for example in the thread "the mystery of sound is mysticism " where you never posted any positive contribution expressely to derail the thread with sarcasms , and this after i posted 6 articles and information about a book describing a very important acoustic revolution right now confirmed by two set of experiments for the benefit of all audiogon readers, you insulted me instead of thanking me and harassed my posts with no arguments only useless sarcasms..
Then this post of you is not the result of a confirmation biases against me , it is a flat upright lie... Idiot do not have shame ...
|
Actually, @mahgister , I do not "trail you in all threads." I try to avoid you. It just so happens that I commented in this thread prior to your rambling diatribes, so maybe you are trailing me? |
«Confirmation bias, as the term is typically used in the psychological literature, connotes Confirmation Bias: A Ubiquitous Phenomenon in Many Guises
https://pages.ucsd.edu/~mckenzie/nickersonConfirmationBias.pdf
It is here for all to read that conflating confirmation biases with lying is reducing a complex process to a simplistic process and conflating the concept of biases with the concept of lies...
i post this for the benefit of all. I dont hopen or think the harassing idiot who trail me in all threads is in a state making him able to any understanding ... This biases in me is confirmed by his behaviour and inhability to ever provide any argument against my post... He troll me because of blinding hate or complete stupidity or a mix of the two ..😊 |
Careful, @hilde45 , you are heading down the road to crazy-town. |
I formulated it incompletely to answered your post which is not even wrong,... Because lying is a possible result of the incoming confirmation related to our biases but not necessary part of the process. Confirmation biases do not begun with a lie , they begun by taking a road instead of another because each incoming steps taken confirm that we are right picking our stating point to begin with ...It is an objective process in ourselves once our biases set had selected a starting point ...And biases are not lies and they do not implied necessarily liying yo ourselves. it is a process that is undetectable at the beginning, picking a road because it fit us like a glove instead of another like someone who realizes, for example, that a favorable review of a product proves that he have made the right choice which is not always true because our biases can induce us in error... An error is not a lie. If you reduce confirmation biases to liying to ourselves , you are not even wrong , because at the end of a process we may effectively begun to lie to ourselves before realizing we have taken the wrong starting point to accommodate us at the times and then refusing to admit that we had taken the wrong road ...Then lies may be implicated at the end of the process but cannot be used to give a definition of the process itself... I know that you know that ... As in a marriage for example , we lie to ourselves at the beginning (if it is a confirmation bias ) not at the end generally even in this totally psychological situation ...😁😊 but the choice of an audio product do not begun generally with a lie to ourselves if we mean to speak about biases, which we cannot eliminate anyway because it is in most case the starting point , and the process of confirmation all along the road linked to them . Biases are not lies, biases can even be positive and in spite of that inducing us on the wrong road.. We can become conscious of our biases. Refusing to taken into account our biases when and once they become conscious is then lying to ourselves.
Then when you said ,it does obviously, you proposed to define the possible end result of an objective psychological process road to be a mere lying process , this is an erroneous definition as the wikipedia definition demonstrate it evidently ... You are probably a good corrector but a way less good thinker...

I walk into a certain big box store with a special high end audio room named after a tree in my front yard, I see some big name audiophile gear with impressive looking drivers and amps with big blue meters. I’m in a large rectangular room lined with speakers against the wall and a bare tile floor. I even see a pair of ML speakers pushed against the wall behind me. The salesman puts on some music. It sounds like a big boombox. The music is bleak and uninspiring. I’m dying just to move the speakers out from the wall. But If I am a young, impressionable and budding audiophile then my conclusion is this 6 figure gear is so not worth the money. I come to these forums and expound on my displeasure and distrust in the high end hifi community. Everything is either snake oil or confirmation bias. This so called hifi sound is a myth. We have so few audio stores left but at least the few that I have been in have good set-ups. Back a few decades, more audio stores than not had poor set-up. Only a few stores had a room with a high end set up to showcase one system vs. rooms with gear wrapped around the walls. But when you walk into a room with a good high end set up, be it a store or in someone’s home, you will know it. |
I have Tube Rolled on a few occasions, where there has been a Selection of Valve Pairs to be evaluated. Tube Rolling is a Two Edge Sword, as change to an end sound, can be noticeably discernable. The change can stimulate a reaction, but does not necessarily create a betterment in sound for the end user, but a difference only. There are Tubes when demo'd as a type from a selection of types. that are capable of making a very good impression. Most demo's I have been party to, have been carried out as a group in attendance. Within the group, there is not always a unanimous agreement, on what is the better tube. With the differences of assessments known, it strongly suggests that recommendation may not be ideal for a end user. |
I bought a pair of NOS Mullard’s for my tube DAC that cost half what I paid for the DAC. I swap them out from time to time with some much cheaper NOS Telefunken Diamond mark’s. The Mullard’s sound significantly better to me. And the Tele’s sound way better than the stock new Sovtek’s the DAC came with. Sometimes you get what you pay for. |
Confirmation biases has nothing to do with "lying to ourself" in particular or specifically ... «Confirmation bias (also confirmatory bias, myside bias,[a] or congeniality bias[2]) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one’s prior beliefs or values.[3] People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs. Confirmation bias is insuperable for most people, but they can manage it, for example, by education and training in critical thinking skills. »
For 40 years by acoustic ignorance i was comforted in the choice of speakers i made, by all i read, all i experienced , till the end when i sold them not because i was lying to myself but because i was ignorant of acoustics and the way to make them really shine at their optimal. ( which would had been like comparing day and night for ANY speakers anyway) My confirmation set of biases was born from all the reviews i read for 40 years confirming the Tannoy dual gold as top speakers AS IT IS plug and play... I did know nothing about acoustics optimization extraordinary tools . I was deluded by their reputation , price tags at the time (high end), and my limited knowledge and all others speakers i experienced put in a living room with no acoustics particular caution confirmed me in my biases...I felt good as i was comforted in my set of biases by time passing and by comparison ...
This is certainly mostly true because we know what are the parameters at play which must be put under controls for a specific speakers design to make it shine in a SPECIFIC ROOM ... A bookshelf is not a big magnepan for example... Once the right electrical, mechanical and acoustical working conditions are adressed we will had natural timbre and listener envelopment. In the window of possibility resulting from the gear pieces design choices and trade-off ... Only passive consumers will have no idea about what could be the optimal experience and how to make it possible for the chosen pieces of gear...
For sure if i travel as a tourist from one showroom to another i will never had any idea about how the next system will be and i will learn almost nothing because it is not me that played with the speakers/room parameters to improve them ... my tourism audiophile will only confirm my own biases i will call my tastes... 😊

Well said. I tried to lie to myself about Be tweeters until I just...couldn't...take it.
That's not true for me. I don't actually know. I have a hold of a few preferences, but one of my experiences with hearing new systems is getting a new idea of how something can hang together beautifully. In this sense, hearing new audio systems is like traveling to new places -- you just can't conceive it until you go there. |
thanks! your testimony is very clear! You said it better than me and with few words...😊
This will help those who think that "tasting " the gear is the key... Or those who think that measuring the gear specs anew is the key ... We dont lack deluded people thinking acoustics concepts and parameters are secondary to gear price tags ...

+1 @mahgister Before I built a properly soundproof listening room and then spending a couple years finding the proper acoustic treatments for it to sound good to my ears, no way was I able to accurately assess the values, positive or negative, of any piece of equipment. |
If you dont know anything else some confirmation biases will had an indefinite life span...😁 I really thought my Tannoy concentric dual gold which were legendary speakers, i really think for the 40 years i owned them that they sound good...😁 in truth because i had no acoustics concepts at all , I didn’t knew and had no way of knowing that they sound atrociously UNDER their optimal potential optimal level... I never knew it and alas! i sold them BEFORE learning acoustics... It is how an ignorant can own a top speakers and had never listened to them really ... This ignorant was me ... 😊 What i just said is so true that my actual modified low cost speakers deliver an experience which is by some acoustic factors better than my past Tannoy even if they are an inferior design . Performance go with the rightfull optimal way we use the speakers specs in a system /room . A better design as with my Tannoy is not enough. We need to install the speakers in his optimal settings. 😎
Then confirmation bias are not mere only short lived placebo illusion , they can be a rightful positive opinion about some speakers which delude us about these speakers real potential because we are ignorant . it is the reason why many reviewers delude us without willing to do it... It is why price tags conditioning works... Or legendary good reputation ...Plug and play and if it is a good product it will play good ...😆 Not always sorry and never so much better than if you had learned how to use it at the optimum acoustic level ...😊

I have returned far more things than I have kept within my system and over many years. As @ghdprentice posted. You will know when you've made a bad choice on a piece of gear, cable or even tweak. |
if you dont know and cannot interpret acoustically with the right set of concepts what you are hearing it is a mere change of S.Q. motivated by unknown factors or a bias to hear some change which we also inevitably project on the change phenomenon with no concepts to guide us consciously ...
Suppose you know your gear as an acoustic experience and suppose you know what parameters change you had done till the new piece of gear was added and their perceived results, for example timbre, bass, imaging, soundstage listener envelopment , sound source width , crosstalk , position , dynamics, reverberation time etc ; then when you add a co0mponent and install it in the right way, your body (not your ego ) remember the last S.Q. experience and can spot the change and interpret it as a feeling ...Your experienced ego will then come and think about the right concept to associate with the feeling but your ego must know the concept to begin with .😁 To verify what i am just claim : ask your old mother in law who never hear a stereo system "consciously" and in an educated way , ask her to describe the sound . She will say " this is good my dear" , what else could she said she had no concepts about sound parameters.😁
i just added silicone rings on the tubes of my preamplifier, my body/brain sensed immediately a change my experienced conscious ego interpreted FEW MINUTES LATER as a better imaging and a more detailed timbre effect without loosing the mids frequencies naturalness and with no loss in the bass and better highs frequencies . The ego is full of biases positive acquired once as in the journey learning curve or acquired as negative biases related to hope, branded name, suggestion , marketing and ignorance but if our body /brain was trained for such in acoustics experiments it will be able to felt a real change and we may be able to interpret it because we had learned how to listen our memory feeling engraved in our body piloted by the set of concepts we studied and we will need to interpret any experience ......😊 If we never acquired these associated feelings with acoustic parameters modifications, the only evident feeling felt would be conditioned negative biases or false positive one . This is why seasoned reviewers used to their room acoustic conditions or any acoustician know what he hear because it had felt it first and recognize which concepts he needs to interpret it ... This is my description of my own experience as i understand it ... We are not consumers passive conditioned dogs we can learn consciously using our own sense apparatus and body doing so ... You cannot build a system/room at optimal level accordingly to his design quality with only negative -placebo effects, suggestions , and price tags and random modifications only .. You need to train your hearing body with the controlled set of parameters in the three working mechanical,electrical and acoustical dimensions. Then you learned consciously learning also to hear your body reactions and then associate it with the right concepts . |
