PREFACE
I again repeat him/it. HI-FIGUIDE is a magazine that doesn't have any intention to conform to the current information in theme hifi, imagined in other themes, for which it enjoys of great respect and prestige near the impassioned ones from a side more experts, from the other it is not well wanted at quite a lot operators, kind those people that well they know that their products are realized according to fashion or, worse, at random.
From this the chronic lack of tried products, due above all to lack of new products of quality and in wide measure for the disinteressamento of many distributors in to furnish HI-FIGUIDE of good products for varied motives: from the lack of direct knowledge of our editing, from motives for opportunity, from habit to furnish in exclusive the magazines friends edite on paper or on web and other anchor.

Among the different ones, the section diffusers it is that on which more we aim.
The diffusers are the component more main points in the chain audio and it are not true that constitute the weak ring. Certainly a diffuser projected ache is an enormous leak opened on the sonorous quality, kind the minidiffusoris. In reality, the weak ring of the actual fittings audio hifi is the source but not the readers or the turntables but the software. For which, if it is true that the quality and sonorous completeness it essentially depends on the diffusers, true it is that with a bad CD granché won't be had as resulted sonorous. This granché will be always obviously something if it goes out of a good diffuser.

HI-FIGUIDE sustains the technical quality to the service of the sound in the planning and realization of any component audio. The evolution of the technique and the technology applied to the audio I am the motor propulsivo of the true hifi and his evolution, the motive for life, better still of survival since this sector is slowly disappearing, submerged by others more successions from the whole family, from his wife and from his/her/their children.
The secret of the constant improvement of the sonorous quality is the slavish application of the laws of the Physics. Some readers have frequently set us questions riguardanti these laws and their individualization. The panorama is not clasped, rather: from the propagation of the sonorous waves to the transport of signal audios from a point to the other one are two dots in an ocean of theories. This would be incomprehensible to as our readers, for which I prefer to make to you a concrete example on the diffuser in examination today, of way can also make an idea reading some listening effected by Massimo Bianchi.

A situation that few planners only know for instance take: a diffuser in two streets doesn't have
