CLASSIC 202 dual mono power amplifier
We have entered a new era of high-quality music reproduction components. The CLASSIC 202 has been designed with care and attention to the smallest details, both internally and externally.
A new circuit design, latest generation devices, a new design for power transformers. All mixed with our twenty years of experience in the sector to guarantee you a sound reproduction with absolute fidelity.
The new transformers guarantee stability and precision of the sound message even at low impedances and high listening pressures. The proven dual mono implementation returns greater signal stability and better channel separation which translates into a wide, deep soundstage with well-positioned instruments within the sound message, literally making the speakers disappear.
This amplifier is capable of handling a wide range of speakers, thanks to its power reserve and an inexhaustible current. In addition, its elegant and modern design fits perfectly into any environment, making it a perfect complement to your audio system.
The heart of our performance: the power stage
the true heart of every amplifier, especially for our amplifiers, is for us a matter of extreme care and detail of fundamental importance, resources and commitment.
CLASSIC 202 is equipped with two transformers with separate windings and wound on a single core for a total power of 1,200 Va which power the rectifier circuits mounted on a single PCB without flying wiring, thus allowing a connection free of contact resistance.
This design shortens the electrical path from the transformer to the final output stages, reducing overall impedance and allowing the circuit to respond faster, controlling the speakers better and more accurately.
The technology in our transformers
DIMENSIONS and WEIGHT :
It is an almost certain fact to ensure good performance, however these two measures if considered as ends in themselves do not guarantee the final result. It is a set of additional factors that determine the difference between a good transformer and an excellent transformer.
We cannot tell you point by point how we build our transformers as we are subject to a factory veto but we can describe the main requirements to understand the efforts made in 20 years of research, study and evolution of materials that we use on a large scale.
Such as extremely low induction, toroidal cores made of iron and magnesium powder, innovative winding and interlacing technique of the coils and last but not least, a copper magnetic shielding on the whole body.
You will not hear a more stable and silent transformer than ours!
Balanced input stage, our philosophy
The most delicate and fundamental part, which must be treated with extreme care, because it is also this stage that as a whole determines the general performance of the reproduction.
This delicate task is entrusted to our proprietary HDCA modules now in their third version. Today even more refined, clear and transparent.
we assemble them with components selected for their linearity and bandwidth characteristics. The circuit operates in open loop and the feedback is so low that it becomes practically negligible.
The circuit operates in pure class A and uses no decoupling capacitors throughout the various signal processing stages.
The power stage
revolves around a cascode circuit design. This proven configuration allows for a wide and extended bandwidth and the power amplifiers are driven by a Darlington-type configuration. 6 pairs per channel of latest generation bipolar transistors ensure reliability and stability in any condition of use, load and current demand.
A new integration of the circuits with SMD components allows for shorter signal paths, greater rejection of noise and a significant reduction in “microphonics” due to vibrations.
The power transformer, in addition to being shielded, is mounted under an iron cover that further increases its rejection of disturbances. The entire filtering bank and rectifier diodes are mounted on a PCB with 70 micron copper without air wiring.
This decreases contact resistance providing a higher current input and faster transfer rate increasing the damping factor and control over the speakers.
