BRZHIFI C3850 Full Balanced Preamp Class A Preamplifier Beijing Transformer Standard Version Silver

Description:
Its circuit refers to the circuit of 3850 preamp for Accuphase. The circuit is looser, more delicate, warmer and more charming than the general preamp circuit, and the sound can be better than that of tube preamp.

The circuit architecture uses operational amplifier as the basic amplifier, adding discrete components to improve the open-loop gain, and using voltage and current dual feedback circuits to reduce distortion. The output tube uses British ZTX450 ZTX550, which is output in Class A state, and the music tastes very good.

Features:
- Wide sound filed, transparent and pleasant sound
- C3850 fully balanced HI-END preamplifier
- Native fully balanced architecture
- Pure HIFI front-end 2.0 stereo, clean, transparent, delicate and mellow sound quality
- The high, medium and low frequencies are distinct. The low frequency dives in place, mellow and powerful, and the mid frequency is thick and full. High frequency is clear and delicate

- Input: Balanced input-balanced output, single-ended input-single-ended output. 2-way RCA input (true balanced amplifier circuit, left and right channel power supply is completely independent, with excellent separation)
- Its circuit refers to the circuit of 3850 preamp for Accuphase. The circuit is looser, more delicate, warmer and more charming than the general preamp circuit
- Circuit Architecture: The circuit structure is an operational amplifier as the basic amplifier, adding discrete components to improve the open-loop gain, and using a voltage and current dual feedback circuit to reduce distortion; the output tube uses the British ZTX450 ZTX550, class A state output, and the music tastes very good, very daring
- Op amp: Using NE5534 op amp, customers can upgrade by themselves. The board does not need to be debugged, it can be installed and welded correctly
