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 .......
YBA diagrams are the eleganceof simplicity. They consist ofadifferential inputof acurrent sourcetransistor, two complementarytransistorsin eachof the two stagesofvoltage gainAclass,followed by output transistors (2 to 6),for a total of8 to 12transistorsper channel. Alltransistorsusedare selected for theirauditoryqualities. The differenceis evident due to the selection of low noisetransistors. The drivershave a verywidebandwidth(40Mhz) andthe output transistorsarehigh current (30 amps).
Great care istaken in choosingnot onlythe value ofcomponents used intheassembly, but alsothe type ofcomponentsand eventhe manufacturerof 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 careistaken to ensure thatthe devices used aredeviceswithhigh efficiency andminimal heatdissipatiion.
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.
