Confirmation and falsification of biases dont have the same impact on everyone...
A modern man dont think that black cat can give him black death...
Myself i dont buy costly high end gear, then i cannot suffer as much from this bias which induce us to perceive a better a system because it is better looking and more costly...
I used acoustics as biases set then i must train myself to perceive and act on real concepts, i am compulsively push to do it then i forgot esthetic of the gear and his price ...😊
Now my main audio bias and prejudice 😁 is : it is not necessary to pay 100,000 bucks to have high fi acoustic experience and it is not necessary to buy costlier upgrades to reach this magical minimal acoustic threshold...
Why ?
Because i learned by experiments that this threshold can be reached , with synergetical pieces of gear EMBEDDED rightfully in their mechanical, electrical and acoustical working dimensions...
Then i am now way more likely to suffer from these biases as esthetics, publicity, higher price upgrade because my learning biases for acoustics concepts parameters controls are too powerful and put the other biases at rest as "black cat" superstition, i became more conscious with basic knowledge ... These old biases concerning esthetic and prices amd marketing act as mice on me now not lions no more ...
Pick the right biases set , study and experiment BEFORE upgrading ; then like me perhaps you will even did not feel upgrade as so much useful anymore and especially not necessary at all cost ...
For those who need the point on the letter "i", my opinion will not change nor my biases set, even with a better system than my actual one, at higher cost and with an improved design.
Why ?
Because audio truth cannot change with esthetic prejudices and higher price biases : in truth audio experience is directly and linearly related to our own acoustics mastery and our own electrical and mechanical basic knowledge first and last, nevermind the price or the quality design level of your gear and to nothing else at the end ...
