iBasso AMP12 Balanced Amplifier Card for DX300, DX320

iBasso's AMP12 Module is a discrete balanced amplifier card for DX300 and DX320 DAPs. Discrete, the Circuit Design of the AMP12 The AMP12 is a 4.4mm balanced AMP and designed for DX300. It is fully discrete on both the voltage amplification stage and the current amplification stage. The amplifier input section utilizes special circuitry that converts the signal into a positive and negative symmetrical analogue waveform. Voltage in this circuit is amplified utilizing a symmetrical transistor common-base amplifier circuit. Characteristics of this circuit is an ultra high cut-off frequency response, which manifests as improved high frequencies, better and fuller details, and an airy presentation. The amplifier output section uses a current mirror collector and a crossed auto-zero emitter that parallels the current to the load. The positive outcome of utilizing the current mirror collector is that, no matter what the size of the output signal is, it will not go into the cut-off stat
