Feature:
• Equipped with coaxial, optical fiber, Bluetooth and other digital signal input functions
• The built-in audio signal amplifier circuit uses imported electronic tubes
• Adopt a hybrid high-precision high-voltage stabilized power supply of electron tube, field effect transistor and integrated circuit, with timbre performance, high voltage stability and low AC ripple
• Common-source common-base amplification mode composed of field effect transistors for the voltage gain stage of the transistor power amplifier section
• Class A current amplifier uses Toshiba brand power tube, the sound performance is thicker and warmer; the output power is 150W (8Ω) x2 specifications
• The electronic circuit circuit cross-connect and de-cross-connect capacitors are the German WIMA brand MKP series advanced audio special capacitors.
• The filter capacitor used in the power supply of the transistor power amplifier is the 10000uf / 80v specification of the Japanese ELNA brand FORAUDIO series.
• The signal input and output lines used in the unit are single-crystal copper advanced audio signal lines.
• Use ALPS large remote control volume potentiometer made in Japan; reliable, durable, low noise, no sound stain, and small error between the two channels
• The output uses large gold-plated binding posts for easy connection with any speaker cable, and the two-wire splitter connection method can also be used, so that high and low audio currents are ideally transmitted.
