The site for enthusiasts of high fidelity sound

If sound production with a “real” high fidelity sound system is disappearing, it is not because the products are becoming les performant or for want of market supply but rather simply due to the evolution of how people enjoy their audiovisual experience. Today it is so much easier to receive the stream of information just by watching a video or TV program rather than solely concentrating on a melody being emitted by our high fidelity sound system.

We prefer to switch on the internet or the television which is so much a part of our daily lives because the message is received by our most powerful sense: our sense of vision. The quality of the sound is obliterated by the power of the images.

Of course, it is not always easy to relax and appreciate the subliminal message contained in certain pieces of music; stress, fatigue and other perturbing factors that surround us distort our listening pleasure. So we automatically turn on the TV and forget our hi-fi. The turntables get coated in dust just as the information annihilates our instincts and sense of premonition.



And yet, close your eyes and let your favorite piece of music invade your senses and take you on an endless journey through space and time.

A passion for sound reproduction

High fidelity sound is a source of pleasure – the pleasure of musical discovery and the pleasure of feeling the sound flowing over and through our bodies.

Are looking for true high fidelity sound? Do you want to improve your sound system, but have been unable to find what you are looking for?

Welcome to SONHIFIPASSION!. The quest of finding the best high fidelity sound reproduction is our greatest passion!

Sharing experience acquired from the discovery of legendary systems and avant-gardists, listening to and discussing with other audiophiles is full of exhilarating moments.

  Definition and criteria for reproducing high fidelity sound


The simplest definition of high fidelity is the manner in which our sound system reproduces sound with very little distortion of the original sound. We have already observed that although loud speakers are a weak link in the system, the acoustics of the room you are listening in also play a major role.


The DIN standards defining the minimum performance of a hi-fi system in the 60’s did not contain the criteria necessary for defining true sound reproduction in high fidelity. Although the response in frequency, the distortion, the signal/noise ratio and the dynamics are included, other major measurable parameters such as the following are missing:

- reproduction of micro information

- general omnidirectional level of the frequencies reproduced (*)

- impulse response and drag

- efficiency


Today, the DIN standard and the term “hi-fi” no longer have the same significance.


1. The evolution and listening enjoyment of an audiophile


In just over forty years of working in the field of high fidelity, I have of course listened to and exchanged hundreds of models.

My first audio device was a Grundig TK121 tape recorder with a 13 cm elliptic speaker and my first hi-fi system was made up of a Thorens turntable, a Sansui amplifier and AR speakers which I purchased at “Parnasse Hifi” (importers of Sansui and McIntosh and manufacturers of Hencot tape recorders).

Of course things have evolved since then, but there hasn’t been much of a technical revolution. My first hi-fi could easily outperform most recent models. The sound of a 2017 amplifier does not produce a better sound than a Sansui AU 555. The Thorens TD 150 is still an outstanding turntable and the Acoustic Research 4X speakers are more than up to par with what is available on the market now.

In fact, lower prices based on the general availability of hi-fi devices has brought down the overall quality (finish, materials).

Just because output power has increased, it does not mean that the sound quality has improved. If power output continues to increase, we’ll probably be able to heat our homes with those devices. Progress has been made in other areas such as multi-channel sound sources with the arrival of information technology and multiple streaming on the internet. Equalizers and other sound processing systems have been a real leap forward.


Huge progress has been made in sound cards. Your preamplifier is obsolete. Now, all the classical functions are contained in the software which also includes the elimination of background noise, rumble and scratches. If in the past minor scratches and dirt on the vinyl disc did not bother me much, today they spoil the listening pleasure.

Certain sound cards are specially designed for audiophiles such as the fantastic ASUS xonar with RCA connections and a high-end headphone output.

The beauty and history of certain preamplifiers still make certain purists tremble with pleasure, but why fight such great progress.
