The c Moy Headphone Amplifier is a headphone amplifier kit suitable for use with portable audio equipment, smartphones, computers etc. The c Moy is a minimalist headphone amplifier based around a single dual-channel opamp. It is based on a design well-known in the DIY Audio community.
We’ve made it into an open source hardware kit that is easy to assemble for anyone looking for a starting point into the world of DIY audio. We use high-quality parts sourced in Japan, including Rubycon capacitors and a NJM4556AD opamp. The potentiometer is a 10kΩ ALPS potentiometer with built-in on/off switch.
The c Moy comes as a kit, and includes the PCB board and all the components you need. An optional brushed aluminum case with custom panels that houses the amplifier is also available.
