Pre 1 Tube Preamp

Jadis Pre 1 - Tube Preamp - Full Balanced

The Pré1 is the brand new line stéreo preamplifier from Jadis. It is a perfect match with the also brand new PA100 power amplifier. This preamplifier can come in either fully balanced or single ended version. The design clearly shows that this unit was developed in the pure Jadis tradition of building quality and musicality.

The tubes

For its electronics, JADIS uses tubes of different brands and various origins, which have specific features.
Tubes represent a key factor of quality; it is for this reason that every batch is strictly analysed in order to select only the best components.
At first, they undergo a primary selection to make them endure several firing cycles (dilatation of materials), allowing the detection of bad air vacuum and mechanical defects (Fixation of electrodes and airtightness of the glass/metal junction).
After that, they are measured one by one to inspect their characteristics and make their appairage (union of parts which are functioning in pairs).

The components

Our small-scale production method, added to many hours of listening, permit us to refine our selection, in order to reach to the optimal result.

The chassis

In extremely good quality surgical stainless steel, the chassis is at the same time aesthetic and hard-wearing, allowing us to guarantee the permanence of our products.

The gildings

The ultimate touch of refinement, the twenty-four gold-plated brass, suiting each of our creations, is also a mark of the JADIS stamp.

The output transformer

Main parts of the creation, the transformers are hand-made on a digital winding machine, following the basic principles born from the passion and research of André Calmettes. Inestimable expertise, and the cornerstone of the high-quality of its products, JADIS keeps its trade secret very carefully.

The cabling

Stemmed from the world of high frequency electronics, the rules and techniques of manual cabling allow us to take full advantage of our equipment and contribute to the sound aesthetics of JADIS.

All Jadis products are made in France.
