Cavalli-Kan Kumisa III（"CK²III" or "CKKIII"）High-End Headphone Amplifier PCB

Printed Circuit Board Project


1、The PCBs sold in the store do not contain any components, and you should prepare them by yourself.
2、To complete this project, high level knowledge of electronics and rich experience in terms of soldering and testing are required.


REF1  Fully Discrete Headphone  Amplifier DIY  Project  PCB


All-discrete fully-complementary topology


No overall global negative feedback.


No integrated circuits used except for the DC servo opamp and voltage regulators.


Complementary input gain stage with complementary voltage sources to set the operating point.


Current mirror with gain.


Complementary push-pull output stage.


DC servo.


ntegrated earphone protection circuit.


all-in-one design, single-point grounding, ground resistance is close to the 0.02 ohm resistance value, low noisedesign.


PCB is small and flexible, more suitable for all kinds of chassis installation.


Schematic & key point of debugging


PCB comes with component parameters for easy installation.


We only refer the schematic of the amplification part of the circuit. If you need full circuit parameter, please read the component value with the PCB by yourself; we do not provide additionally.

please keep test point voltage close enough to it, +-20% is also permitted.
