And where exactly have I - or another poster in this thread - done that?
As âdataâ, music is secure⊠you can only âoptimizeâ things when it becomes âaudibleâ, where the human ear/brain combo is always up to trickery. If you disagree with me, my setup will still sound exactly the same. Lots of âEmperors clothesâ out there⊠letâs not forget to enjoy the music!

Everybody who think others canât have heard what they heard, without knowing who the other is. That was not for you especially, thatâs for all that think the people that hear something « imagine differences ». Total irrespect to other people for me to think they are just fool, but they canât realize itâs a simple matter of respect, and I canât understand that.
Maybe a litle less drama is in order here. Not all opinions and statements are of the same value. Especially the âI saw what I sawâ or âI heard what I heardâ argument is rather weak. The human brain fools itself quite easily.
If someone says they saw a flying pig (or an alien spaceship), there is no imperative to believe them without further evidence that there actually was a flying pig. If someone says they hear acoustic differences caused by soft- or hardware, when there is no measurement that either the soft- or the hardware have changed anything, there is no imperative to believe them without further evidence that there actually is an acoustic difference.
Their perception might have been as they state, but that doesnât mean itâs an accurate description of reality. As I wrote, the human brain fools itself quite easily. So, this is not about âtotal disrespectâ at all, but about healthy skepticism.

True, but the problem is that we donât have the ability to listen to everything we are interested in. Nowadays we have to make a desicion based onâŠyes what exactly? Thatâs maybe the reson why people get so obsessed by software differences, they can be downloaded and easily tested. Thatâs the only remaining thing people can get a grip of sometimes. Another pair of loudspeakers which would make up to a thousandfold of a difference is much more difficult to compare. So yes, mesurements donât tell everything but st least a whole lot more than no measurements at all.

Lol, and you donât understand why I can feel a bit in the drama Roland⊠sadly just what I said, please let me stay in the drama and return to my nuclear reactor pilot job, bad perceptions and fooled brain 
Iâll tell my friends in different audio systems that have the exactly same perceptions to make quickly a lobotomy to lose all these imagined perceptions.
Nyquist, do you know what kind of speakers I can listen to and sometime compare directly in the same room, and conditions of listening, in different rooms, Andra3, Vivid G1 spirit, Marten duke2⊠bridged Luxman M800 power amps, different amplifiers⊠softwares are the last thing I listen to.
Best regards, Nicolas.

Please donât show off, it makes no sense.I can tell what I listen to everyday but that is useless to you, me or anybody else. Most people do not have the ability to try different hardware in their own environment. They have to make a descision on somethingâŠand the 1 million dollar question remains, on what exactly? How did you come to the descision to buy your equipment? Thatâs what Iâm interested in, not what you did buy in the end. Show off is the last thing we need. Most of the time descision are made on reviews, opinions of others etc. That makes no sense either because they face the same problem as everyone else. The days of just listening without measured data should be long gone by now.

Iâd heard my speakers in store and liked them, so when an opportunity came to get some with less than perfect finish for a substantial discount, I took it. Iâve upgraded the tweeters, routed some space around the mids and replaced the inductor in the mid crossover with an 8wg monster from North Creek. They measured OK but I think I just fell in love with the sound to be honest.

Nice speakers, pair superbly with Devialet.
As are the fanatically charged measurement only types that canât help themselves from saving EVERYONE. ASR has a lot of openings 
Correct, HiFi isnât difficult per se. Letting people enjoy it apparently is for many.
How important can a difference be that takes the listener two days to perceive?

Well, you were right!
Thatâs not the point, the point is that if you listen a short while you will be affected by expectation, and think you hear an improvement. But at least for me, that expectation bias is reduced and even removed the longer I listen,
But of course if the difference is very big you can determine it much shorter.
By DEFINITION expectation bias is something you arenât aware of⊠Such claims are untenable.

You can learn to compensate for them, and you will even get verification that your process works when something that first sounded good (due to bias) sounds worse the other day.
I can take an example: I borrowed new speaker cables a while back, connected them and thought wow sound awesome. But the next day they didnât sound so special, and then I switched back and found that the old ones sounded better. So the initial âwowâ was mainly due to expectation bias, but the next day it was more objective listening.

If itâs a sighted test youâre just switching your expectations. This has been studied to great length. If you can see or know the configuration change then your listening tests are invalid. Thatâs how strongly the subconscious controls auditory perception.

I just wish my subconscious had cheaper taste.

In the context of this thread, I agree 100% with @MenloBobâs statement. But of course this doesnât mean that we can NEVER hear any differences in an A/B comparison if we see or know what we are listening to. Nobody confuses âwoofâ and âmeowâ just because he sees a dog and a cat right in front of him. Even if the dog meowed and the cat barked, the difference would still remain easily discernible. Our expectations influence how we perceive the world around us, but of course they arenât the source of our perceptions. Expectation bias isnât a mental illness, and it doesnât cause hallucinations. Our biases mainly result from the (necessary) selectivity of our perception.
