Signature line#

Signature is the most exclusive line of YBA products. Only the highest quality components, materials and technologies are used in the production. These products provide excellent standards and are considered uncompromising in faithful reproduction of sound. Each series product consists of two solid elements of an aluminum housing. Simplicity of performance meets extremely high and complex performance. All components of the Signature line are manufactured in France under the watchful eye of expert Yves-Bernard André. His personal supervision is a guarantee of providing the highest quality product in every detail. Signature series products are available in stereo or 2 x mono configuration, preamplifier and CD player.


The circuit used in this YBA amplifier is completely symmetrical; this cancels any defects introduced via the power source, minimizes parasitic ground currents and avoids any need for passive components in the signal path.

The number of components has been minimized; the signal traverses only transistors. No passive components alter the original purity of the musical signal. The input stage is of the complementary double differential type; it is followed by a pre-driver stage, which allows the adaptation of the impedance and initial amplification of voltage. The pre- driver stage is followed by a third stage, which completes the amplification of voltage; it distributes the current and voltage necessary to the output stage, which is directly coupled to the speakers.

The geometry of the circuit has been optimized to reduce the distances between components and the connecting wires to the absolute minimum: only a few centimetres at the input and output of the

amplifier. The transformers are suspended in order to reduce the transmission of their vibrations to the rest of the amplifier.
