Bakoon HPA-21 review – a unique headphone amplifier - Sound News
Teknisk forklaring fra link.
“The input voltage signal is converted to the input current signal by the input resistor. As the input impedance of the SATRI-IC is close to 0 Ohms, the voltage signal is converted preciously into the current signal.
Then the input current signal goes into the SATRI-IC, from which the output impedance of the signal is converted to above 100 M Ohms, while the current signal itself remains the same. As the output impedance is very high now, the output current signal goes into the output resistor without any loss. By this output resistor, the current signal is converted back to the voltage signal.
Summing up this procedure, the SATRI Circuit’s formula of the overall gain level can be just simplified, meaning that the amplification involves two resistors only. As a result, the circuit is now perfectly linear without uses of any other complicated unnecessary circuits, which would only distort and introduce more noise source in the circuit.”
