The Son of Zen is the most massive amplifier project I undertook. The result is really impressive. The performance of this amplifier is very good, challenging very expensive amplifier owned by some of my friends.

I did make some adjustment to the Son of Zen to fit my usage. This included a DC blocking capacitor and a capacitor multiplier power supply.
