Following on from my last post, looking at integrating my existing equipment presented a small headache. I already have a headphones dummy load which, whilst not providing the exact impedance of my current headphones, does the job. The problem is that the outputs from the dummy load are BNC sockets, as it was originally designed…

A modern take on the CMoy Headphone Amplifier
Anybody who has browsed these pages in the past knows that I keep an eye on certain people’s projects, one of those being Uffe at Slowdiyer. Recently he has been experimenting with USB-C power supplies, one of the offshoots from this being an updated version of the’mini-pre‘, a variant of the classic Chu Moy headphone…
Elliott Sound Projects P113 Headphone Amplifier
I’m a fan of the projects on Rod Elliott’s ESP site as they come with lots of information to help you understand the circuit, and most are simple and robust enough for entry-level DIY hobbyists. Yet this does not mean these are low audio quality circuits, Rod specifies this P113 headphone amplifier as a very…
Headphone amplifier power outputs
Following on from my last post where I showed the headphones dummy load, I thought I would post the measurements I obtained from the other headphone amplifiers I have built. It’s also an excuse to play around with my new toys. I knew that eventually I would end up with an oscilloscope, I spent a…
Ray Samuels Audio XP-7 Headphone Amplifier clone
I bought a mixed bag of boards recently and came across this one knowing nothing about it, apart from it appearing to be a headphone amp. I finally found out that it is a clone of a commercial project – the Emmeline XP-7 which has been around for a number of years. A cursory search…
CMoy headphone amplifier version 3
After building my Mark II CMoy headphone amplifier I decided to make a version which resembled more of a desktop model.
CMoy – A beginner’s headphone amp
After assembling a couple of kit amps with differing results I decided to have a go at a ‘proper’ DIY amp, built from scratch on a prototype board.
Classic 47 Headphone Amplifier Kit
This was the first amp that I attempted. My expectations were low but the rationale behind buying it was that it was I wanted to practice soldering and have a (hopefully) working product at the end of it. Prior to this I was practicing on a perf board with wire.
