Founded in 1983, the French vacuum tube manufacturer JADIS, the designer Jean-PAUL CAFFI 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 consistent characteristics of the brand's pure class A, vacuum tube self-biasing, and triode push-pull amplification. The products retain the consistent romantic tradition of the French, all of
which are exquisite and noble. JP200 is a very popular flagship preamp launched by JADIS. It uses X7 for two-stage voltage amplification and uses X7 for cathode output, so that the impedance of the front and rear stages can be well matched and the load capacity can be improved. In order to obtain a larger output current and lower
output impedance, the circuit uses double triodes in parallel, which is also one of its characteristics. Its sound quality is mellow and transparent, with a stronger musical taste than Marantz 7, and its high frequency and low frequency are also significantly better than Marantz 7. suitable for enjoying classical music!
1.The amplification and power supply parts are independently designed forleft and right channels to improve separation and control, as well as stability!
2.The power supply circuit adopts 6z4 or 6x4 bile rectifier (change two jumpers to use 6z4 and 6x4 interchangeably), Japan Kubota type field effect transistor high voltage voltage regulator circuit, 3-level CRC filter, Japan Panasonic no large volume fever filter Capacitor, filament LT1085 voltage regulator, these are the guarantee of good sound!
3.The amplifying part adopts 6 old red Weimar coupling capacitors made inWest Germany, EIZZ 24K real gold plated signal selector switch, Taiwan-made copper pin resistors and imported KOA resistors are all combined, double fever-grade R cattle, double fever-grade Power regulator board, Japan's Kanaimei signal line and so on.
4. Chassis size: length 430*width 360*height 90mm (all-aluminum alloy case with good craftsmanship)
