The Bakoon EQA-5620mk3 has been developed for the purpose of reproducing analog signals of gradation of infinity (the feature of the analog record) to the utmost precise accuracy.

In order to realize their goal, Bakoon adopted a SATRI equalizer that converts the change in the frequency response of the RIAA equalizer into gain change. For this reason, it is possible to reporoduce sound sans distortion without clipping the signal with the RIAA equalizer.

By using an MC cartridge it is possible to take full advantage of the characteristics of the current input SATRI circuit. Since the current output is large also in the MC cartridge (which has to use the step-up transformer or the head amplifier because the voltage was low) it is possible to reproduce low noise which could not be considered until now.

Bakoon connected the SATRI power amplifier with the SATRI-LINK output using a dedicated SATRI-IC, making the output impedance several tens MΩ, and able to make it equivalent to the power amplifier in an insulated state. For this reason, Bakoon eliminated common impedance and noise induced noise. Also, the occurrance of noise due to the switch operation is controlled by the CPU successfully reducing the noise due to operation to an extreme.

The SATRI circuit which does not apply negative feedback can reproduce music information without leaving it and as such is possible to obtain a deeper impression from music.
