Testing each component

Each of their products is bound by a very rigorous sequence of tests and inspections performed by highly qualified technicians. Endowed with thorough in-house training, they are able to oversee the entire manufacturing process, each bringing specific technical skills to the table. Thus, all stages of assembly receive dedicated checks, carried out using the most powerful technology. When any product has a defect, however small, during the testing phase, it is immediately withdrawn from the production line.

JADIS Output Transformer

One of the most valuable features of JADIS amplifiers is the output transformer, an indestructible masterpiece providing the amplifier with absolute stability regardless of its load, which is completely manufactured by JADIS. It is hand-wound using an original technique and then encapsulated in a special resin that guarantees maximum waterproofness and thermal stability. This process maximizes thermal stability and eliminates the disturbing hum of the transformer.

Unique performance of JADIS amplifiers

The specifications in terms of power are surprising: the maximum acceptable power is 2500 W before saturation. JADIS amplifiers are the only amplifiers in the world that have these characteristics, offering amazing dynamics in both low and extremely high tones. Most of them operate in pure class A. For these reasons, they are the ideal amplification source for any loudspeaker regardless of its impedance curve, type of operation or power handling.

Speakers are the key factor

For its electronics, JADIS uses tubes of different brands and origins that have specific characteristics. Electrodes are a key quality factor; for this reason, each batch is rigorously analyzed to select only the best components. They first undergo a primary selection to withstand several firing cycles (dilatation of materials), which makes it possible to detect poor air vacuum and mechanical defects (fixing of the electrodes and airtightness of the glass/metal junction). They are then measured one by one to check their properties and make their appearance (joining parts that work in pairs).

Continuous improvements to the Jadis MKII and MkIII

Although Jadis don’t change their model numbers often, they do go the route of continuous improvement, so there have been many improvements over the years. The latest Jadis MkII and MkIII models feature significantly improved transformers. The magnetic circuit, copper wire, insulation and manufacturing techniques of the transformers have all improved. The copper wire has been upgraded to a higher purity wire. A new resin-coated finish reduces noise levels, while improved circuitry and improved high voltage filtering result in cleaner current.

In the preamps, the internal wiring has been upgraded to a higher quality silver cable and more silver wire is used everywhere. The MC phono stages have been upgraded with higher quality enclosures and components. The chassis has been upgraded to surgical grade stainless steel and internal components such as the diode bridge and capacitors have also been improved. A new gold front panel finish ensures your Jadis will look beautiful for years to come.

Who is Jadis suitable for

Given the design and technical specifications of each Jadis product, this brand is primarily for enthusiasts of a more natural and warmer sound, as well as a pleasingly characteristic velvety bass and musical expression.

Where is the primary use of this brand

Jadis products are usable pretty much anywhere, and therefore whether in the home or recording studio.
