What Problems FA2 Solve

We know that the current output stage of a general amplifier consists of two amplification lines: one line handles the negative (negative half cycle) output signal, and the other tube processes the positive polarity (positive half cycle) output signal. This can minimize the quiescent current, but to drive 8~600 ohm headphones, it must have a large amplitude of voltage and current; there are 4 or 8 tube portable players on the market, but not working in Class A,There may be some distortion, called cross distortion. It appears at or near the zero crossing of the output signal. If the two branches of the circuit do not match exactly, crossover distortion often occurs. FA2 completely solved the above two problems and shared the circuit architecture: the digital receiver of FA2 adopts AK4497EQ DAC Chip, IV - Ti(BB) OPA1632-Fully Differential I/O Audio Amplifierr; OP adopts OPA1612 (bipolar-input operational amplifiers-completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.), Toshiba 8-pair tube current amplification; among them, OP level (voltage, current amplification stage) adopts differential balanced output and works in Class A state; From DAC output to Toshiba 8-tube full direct coupling mode, ensuring high fidelity, High signal-to-noise ratio (FA1 signal-to-noise ratio (121db)), good dynamics without distortion; with good headphones, experience music playback in depth;
