Saying an half truth will not solve the problem...
The ear can deceive YES and the measuring tools can deceive us also when we focus on one aspect of sound only, or when we focus on the GEAR or the TOOL instead of the acoustic multidimensional aspect piloted by our hearing...
People throw their money in upgrading the GEAR because the measuring tool say so in the publicity...
Instead of upgrading toward costlier components, learning acoustic by ear will liberate them from the consumers market conditioning selling the GEAR because of some MEASURED specs say so , underestimating acoustic experience of our trainable ears is the sin of the measuring fads and the cardinal sin of the SELLERS.......
Acoustic is not only a set of equations it is also a brain/ears experience and the dynamic correlation between the two in real time in our room ...We must learn our room...
Saying that the ears are not trainable because it cannot be trusted is like painting yourtself in a corner....
Repeating that the ears are not to be trusted is an half truth worse than a lie....
The problem for many people is they trust their own perception. This just does not work well for hearing. The result of all this is an entire industry based on deception. As long as it is not my money why should I care?
