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…

Elliott Sound Projects P97 Pre-amplifier
Following the completion of the PeeCeeBee power amplifier, I wanted to build a pre-amplifier to go with it. At present I’m using a Schiit Modi 2 & Magni 3 combo for DAC and preamp duties, and whilst these are perfectly adequate, I wanted a preamp to match the style of the PeeCeeBee. In contrast with…

PeeCeeBee V4 Class AB amplifier
This latest build is the PeeCeeBee, a discrete Class AB amplifier, now in its fourth iteration. It was designed and made available by Shaan through a group buy over at DIYAudio. He has recently designed a very nice PSU as well and so I ordered a couple, one of which powers this amp. Although Shaan…

Workspace listening setup
For this short post I thought I’d just show the setup I’m using for the spare bedroom now that both Idiot Children have left home. The room still has a bed but I’ve managed to have a desk for my electronics.

CMoy Mark IV – preamplifier
Whilst many modern sources provide enough voltage to feed a reasonable signal to amplifiers, some, such as the Pass ACA, may benefit from a boost in gain, particularly if paired with inefficient speakers. As I had most of the parts, I thought I would try a variation of the CMoy headphone amplifier as a preamplifier…

Quick speaker build project
I’ve been thinking of building some speakers for a while now, and with the imminent departure of Idiot Child No.2 to university, an excuse has arisen – that being a simple audio set-up for her room. The project had to be relatively cheap as I don’t have much spare cash for the next few months….

Attack of the Clones
What does a $3300 amplifier sound like? I suppose I’ll find out soon when I finish building a Gainclone amplifier. A Gainclone, as its name suggests, is a clone of an amplifier which first appeared in 1999, the Gaincard built by 47Labs. Heralded for its sound by Stereophile magazine, people were nonetheless surprised to discover…

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.

Nelson Pass ACA v1.5 DIY build
When I first started searching online for information about DIY audio, I came across the DIYAudio forum, as I expect most people do. Feeling bewildered, I clicked through to the store and saw what seemed to be the answer to my problems, the Amp Camp Amplifier, designed by Nelson Pass. This is a complete kit…

CMoy Headphone amplifier version 2
After building my first CMoy amplifier, I wanted to have another go and correct some of the problems I had with the first build. Specifically, I wanted to see if I could get rid of the hum and find a better case.
