We are proud to announce our first DIY audio kit: The cMoy Headphone Amplifier kit.

The cMoy is a headphone amplifier kit based around a single dual-channel opamp, suitable for use with portable audio equipment, smartphones, computers etc.

It is based on a design well-known in the DIY Audio community. We've partnered up withPraktisk Audio, a newly launched audio brand and 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 cMoy comes as a kit, and includes the PCB board and all the components you need.

No amplifier would be complete without an enclosure, so we are offering a choice of two beautiful aluminum enclosures. Both are Made in Japan by the company Takachi.

The standard enclosure is in aluminum with custom-made black acrylic front panels. The deluxe enclosure comes with beautiful custom-cut aluminum front and back panels with high-quality silk screen.

The only thing you will need to add yourself is a 9V battery, audio cable (mini jack male-male, available in our shop) and headphones.
