What does Hi-Fi Even Mean anymore?

The human timbre voice is the golden rule in audio like in music...

We are shaped by our daily life, by history, and by evolution to detect, identify, and locate voices....

For me there is no other rule to fine tune acoustically my system...

We all know how a voice must be....Or is not.....Almost all music is distributed around the critical window frequencies range of the human voice.... If a choral work sound good in a stereo system with a location and a clear distribution of children,female and male voices with all the difference between the register, and the indivuduals, this system will give a good rendering of any instrument....

The worst music for fine tuning a system is any amplified instrument.....The worst genre is pop or electronica....

The best is choral voices with children,females and males voices...

For instrument i pick one very demanding but very well known : piano....
My second best is a brass quartet or quintet with tuba, trombone, horn and trumpet...
My third is Vivaldi strings.....
Or some symphonies....

If all that sound natural and 3- D you are done....

Interesting article Thanks...

Interesting article which adress in NO way at all the Audio problem directly....

I am flabbergasted by the imperative of market consumerism on audiophile....

And all these men sells something.... Except the solutions....


 The history and evolution of tech and sources are interesting for sure...

But the definition of what is Hi-Fi is not linked to only and mainly to  the gear, but mainly to the way we install it in his working dimensions whatever it is ....
