Founded in 1983, the French vacuum tube manufacturer JADIS, the designer JEAN-PAUL CAFFI itself is a person who is obsessed with music and has a good understanding of the physical characteristics of live music. He insists on maintaining the brand's pure A-class, vacuum tube self-biasing bias, and triode tube push-pull amplification. The products retain the French romantic tradition, and all reflect the exquisite elegance. JP200 is the most popular flagship preamp of JADIS. It consists of 12AT7 two-stage common cathode A and one-stage direct-coupled cathode output. The main amplifier circuit is used to make the circuit dynamic and anti-overload better. The circuit is more stable, and negative feedback is introduced at the output and input stage current feedback. Therefore, double negative feedback can make the distortion very low. The previous stage amplifier has extremely high index and excellent hearing.
