AvantGarde web site (January 2004):

AvantGarde products comply with the philosophy of their inventor.So exactly what is this philosophy? Quite simply it is one of putting quality above all other considerations. But that is easier said than done and starts with attention to detail. An example: In AvantGarde's workshop, every single transistor is tested manually, which means considerable extra expense. 96% of the transistors tested do not come up to standard and are therefore not used! This rigorous procedure is made all the more problematic by the fact that the lead time for bipolar transistors is up to 18 months.

Systematic elimination of capacitors

Bipolar transistors were only discovered recently. However, Fred Gassmann already uses this new technology. Their high speed favours a transparent sound. This is also a pleasantly warm sound, as there are only transistors and resistors in the circuit. It is the principle of amplifiers and preamplifiers to avoid all capacitors which make the transistors sound hard. Each transistor has a capacitance which is compensated for by an ingeniously-devised circuit board layout. The printed conductors on the board must be free of reflections up to 100MHz. The sound of valve amplifiers stagnates with time. Yet that of transistor amplifiers is also subject to fluctuations because of the constant changes in capacitance. This is not the case with Avant Garde, because no capacitors are used in the layout.

Loudspeakers as carriers of emotions

The loudspeakers of AvantGarde have also won much praise in Germany and France. The aim is to offer loudspeakers with an open sound that let you "feel the emotion" of the music. Consequently, no shortcuts are taken here either in terms of quality.

The bass driver is made of Kevlar, the lightest yet most rigid material. Any resonances arising are filtered out. This is again easier said than done. Stefan Wyss of AvantGarde has worked hard on this for three years . . .

In the center is your desire of sound

Roomfiling, warm, rich, deep, clear as a crystal. AvantGarde systems will be adjusted in details with our fine-tuning at home, in your rooms. Founded in1989 it took us only two years to get on the covers of the international trade press with our first compromiseless high end product. Since then best grades are standard. Basis of success : "I chose every component myself, Every single component is handmade and signed. We are running demanding tests on Your masterpiece before I testlisten each one personally . Our manufacture therefore only produces 150 components per year (this can cause waiting times, which our clients usually willingly accept)." "We warrant our first class service at home and continuing Upgradings so you are always up to date. In the center is your unconcerned listening pleasure." Fred Gassmann

Or as editor Karl Breh of STEREOPLAY puts it : "I' m surprised how clear it can be herd, but the sounds coming out of the AVantGarde are much clearer. There is absolutely no colouring."


Fred Gassmann, for 20 years a passionate in the HiFi business.

1979 He establishes his first HiFi shop. At that time he is already producing loudspeakers of a high quality.

1988 Import and distribution of australian high-quality components.

1989 Gassmann Akustik AG is being founded. Fred Gassmann (engineering) with his brother Adrian Gassmann (selling) and shareholders Daniel Peter (public relations) as well as Ralf Negele (electro-technician) are the founders of this enterprise. This team brings out several series of high-quality loudspeakers.'

1992 A new AvantGarde series is brought on the market in Germany. The critics are enthusiastic, especially about the power amplificator A1. The famous magazine "Stereoplay" emphasizes that they have never tested a better amplifier before. Also in France the reactions are full of superlatives. AvantGarde amplifiers are powered on accu so that there is no pollution coming from the tension. This new technique gives the amplifier a warm and clear sound free from disturbing noises.

July 1995 The first completely self developped integrated amplifier is commercialized. Despite the use of classical transformators it reaches the same level as the accu powered version but it costs less.

1996 Fred Gassman develops a new, as unique as outstanding CD-player. Its innovation is its triangular shape and its suspension.

1997 Year of the foundation of AvantGarde High-End AG.
The great success of the AvantGarde components leads to the change of the firms name.
