Yves Bernard André – the Founder and Designer

I have been designing audio products since 1971 and hold several patents.

My company operations commenced in 1981 with just one amplifier and one preamplifier.

YBA products have always been and still remain my absolute passion and I believe this passion is evident in the design of every product bearing the YBA name.

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).

My designs rely on the following criteria

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 and reliability in 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 dissipation.


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.

“I am extremely pleased to be able to include some of my ideas when designing products. You will find a In-depth interview that will give you more information about why we design our products and how we do it.

The Spirit of YBA

To accurately reproduce music takes not only a high level of expertise, but a love of music and an understanding of how it is produced. It involves a need to be able to stir those emotions which music arouses in us all.

And so in addition to a passion for music, discipline, precision and patience are key elements in the philosophy which lies behind YBA’s products.

Musical Quality

Sobriety and simplicity are key to the excellence of YBA.

Our aim is to have the listener forget the electronics and enjoy nothing but the music. Every product we make is treated in the same way, from the least expensive through to our high end.

Numerous prestigious awards have been given to YBA over the years and in all cases the products receive high praise for their musicality. It is such a simple thing, but something that takes exceptional talent to achieve.


Owning a YBA ‘instrument’ is a long-term investment, both from an emotional standpoint and often times financial. The quality of its manufacture is guaranteed to maintain its value through the years. The limited number that can be found on the second hand market, coupled with the value put on those products, undeniably attests to that quality.


The shorter the signal, the better the sound. To be able to reduce the number of components and consequently invest in the highest quality of those used, is one of the great strengths of YBA.

Importantly, specific attention is therefore given to even the smallest details. To further ensure the result, every product is personally listened to before it is passed.


Another great strength of YBA lies in its planning for future products. It is hoped that once a YBA product has been purchased that it will remain with the user for many years. And so if any improvements are possible they are announced so an owner can choose to upgrade if desired.
