Yves-Bernard André has been designing audio products since 1971 and holds several patents. The company commenced its operations in 1981 with just one amplifier and one preamplifier.
YBA always has always been and still remains Yves-Bernard’s absolute passion. This passion is evident in everything he undertakes. The philosophy behind his products is simple.
Quality is a constant state of mind
It is a matter of passion and experience....not a matter of standards
Technology is not an end in itself
The pleasure found in listening must be our only guide
He is happy to share some thoughts behind his designs .......
Products without compromise
YBA diagrams are the elegance of simplicity. They consist of a differential input of a current source transistor, two complementary transistors in each of the two stages of voltage gain A class, followed by output transistors (2 to 6), for a total of 8 to 12 transistors per channel. All transistors used are selected for their auditory qualities. The difference is evident due to the selection of low noise transistors. The drivers have a very wide bandwidth (40 Mhz) and the output transistors are high current (30 amps).
Electronic components without compromise
Great care is taken in choosing not only the value of components used in the assembly, but also the type of components and even the manufacturer of these components.
Most of them - such as connectors,transformers, cables, the solder and resistors are specially manufactured for YBA in France.
Simplicity andreliabilityin the design
This is the heart of the products. Special care is taken to ensure that the devices used are devices with high efficiency and minimal heat dissipatiion.
Indium is used in particular and specific places in order to decrease the variations of temperature and to improve conductivity.
YBA audio products are truly innovative, based on “Memory Free Design Technology” to avoid thermal,vibration, electromagnetic and electrostatic distortions.
