자세히는 잘모르겠고,부속품을 유명업체것을 사용했고,중요한것은 중요기능을하는 콘덴서는 동사에서 직접만들어 사용하고 있는것으로봐선 노하우가 있는것은 확실한것같습니다.
Xa3200s is a premium HI-Fi pre-amplifier specially designed for music appreciation. Every sound channel of this appliance adopts two 5670 or 6N3 electron tubes connected in-parallel into SRPP to amplify, at the same time uses one SRPP constituted by 12AU7 for output, also adopts the direct-coupled intervalve, which gives relatively wide frequency response (10Hz-100kHz, +/-1dB) and good dynamic and low-frequency control abilities. In addition, the power supply of this appliance takes the characters of former XA3200MKII model, adopting VT commutation and voltage-stabilizing, which makes better matching between inherent resistance, performance and amplifying circuit. The control section uses single chip microcomputer. The sound control uses imported ALPS motor potentiometer. The sound source selectively adopts relay to realize the feather-touch switch over. And all of the functions can be remote controlled. The operations are convenient, the reliability and fidelity are better, and handling is easier .
The materials used in this appliance are very fine and polish, using 0.5W DALE resistances, WIMA and RIFA and special Xindak MKP capacitances, premium gold and silver plating signal wires. Interior the zinc coating plates are used to separate the power supply and amplifying circuit. Therefore either the mechanical strength and electromagnetic interference resistance capability is outstanding. The remote control is made from wire-drawing die of Aluminum Alloy.
Overall sound quality: the sound of this appliance is deep and solid, transitions are smooth and in order, music is pure and mellow, overtones are rich, and musicality is great.
