The truth hurts for some........
Most people forget.......how to refer. When you don't understand sound, you can not understand audio. Most cables in audio are what we call; emphasis cables. That means that those who created them put the focus on certain frequency response. But....a cable needs to be as linear as possible
What all emphasis cables have in common is the fact that they all can not reveal all aspects of sound. And this can easily be proven by sound and stage. Even many fuses are emphasis fuses. And again the same limitations will occur as what emphasis cables show by sound and stage.
It is very easy to change sound and even stage by adding or changing a part of an audio system. But......the question is does this changement create an improvement. So you need to be able to reveal and observe all aspects of sound within 1 tenth of a second. As your system needs to be able to reveal all those aspects of sound.
It is the complexity of sound that makes audio so difficult to understand and adjust. But you need to understand all the different aspects which influence sound and stage. As you need to understand in detail what sound is and on which properties it is being founded.
So even before you can judge one part of what you change in your system. You need to describe the full DNA (all aspects it owns and how these different aspects are being carried out) of each part in your system. After that, you need to describe in full detail the influence of the acoustic, electro-smog, magnetism and high-frequency noise on your sound and stage of your system. And it needs to be done independently.
Without this audio is 100% pure gambling.
I sold and tested many different brands in cables in over 20 years of time. When you compare and test cables you often can hear that a manufacturer puts the focus on a certain frequency range.
This makes people often think for example that the low frequencies increased in power and control. But they forget that these choices often create other limitations. In other aspects of sound.
I will not use names anymore. Often 'emphasis' cables are not able to create a huge level in 3D. And they often can also not reveal diversity in height like brands who are what we call; more linear. This means that all frequencies are being equally carried out.
We are now discussing to do presentations with Conservatory students. Manufacturers with who we do business are interested in it. This is the best and only way to show and teach people how voices and instruments sound and how big they are in space.
The idea is to start with a voice or a person who plays an instrument. After this, we want to let people hear how a Tru-Fi system plays the same kind instrument.
In the end, emotion is the only key to success in audio. This is why we want to show people how human emotion works regarding music. So it makes sense to use real voices and instruments for that.
