Soul of Sound Works
Made for listening
Things built because they needed to exist.
Audio electronics have been a constant for most of my life — building, modifying, experimenting, listening. Most of these works started with something I wanted to hear, use or understand better. So I built it.
Some remained one-offs. Some became small series. Others simply led to the next thing.

43004 Amplifier
Four channels. 300 watts. 4 ohms.
Designed for a large-scale line array system. Built in 2021 with a custom analogue front end and dedicated control logic in just two rack units. Five were built by hand. -
Club Soundsystem
Sensitive. Powerful. Relaxed.
Inspired by classic guitar cabinets, this four-enclosure system is finished in orange Tolex rather than paint or veneer, giving it the visual character of classic stage equipment.Explore Club Soundsystem →

BOB Linear Power Supply
A different approach to the 808’s external supply.
BOB retains the 808’s original architecture while approaching its external power supply from a different angle. A deliberately lower supply voltage reduces the thermal load on the internal regulation, while rectification is moved into the external chassis

OOQ 100 Amplifier
Three years. Four designs. 100 watts.
Three complete designs were set aside before OOQ 100 began again from a blank sheet. The result is a deceptively simple amplifier with interchangeable input modules for uncompromised connection.

3160 CDP
One last line of defence.
Built for actively driven compression drivers, 3160 CDP sits between amplifier and driver as an independent safeguard. If the worst happens, it gives the diaphragm a chance to survive.
-
Line Array
Six modules. 600 kilos. Linear phase.
Built for home listening around acoustic performance rather than convention. Developed with acoustic expertise, precisely measured and FIR-controlled, its six modules work as one coherent system.

Ultra Low Noise Studio Power Supply
24 volts. 3 amps. Built for silence.
Developed for the DK preamplifier and classic 24-volt studio electronics. Choke filtering and an ultra-low-noise output stage provide clean, stable power with plenty in reserve.
-
OOQ 20 Amplifier
Twenty watts. Transformer in. MOSFET out.
The OOQ 20 is the Soul Circuit, scaled to 20 watts. Made for high-efficiency systems, where the first milliwatts matter more than headline power. -
Split 4
Two in. Eight out. Nothing active.
A passive XLR distribution box for sending a stereo signal to four destinations. Light output isolation and HF filtering keep the lines separated and clean — without adding another active stage.
-
4360 High Resolution Studio Monitor
Four cabinets. All Alnico. Fully active.
The big studio monitors of the 1970s and 80s were the starting point. 4360 keeps what made them special and builds the rest around what is possible today.
-
Broadcast Preamplifier
Old modules. New context. Three sources.
Built around Danner-format studio modules, it brings classic broadcast architecture into a dedicated three-source preamplifier. Original hardware, rearranged for a different purpose.

Schulz S 602
No. 001. Mono. The first finished one.
The first complete amplifier I built for everyday use. Before it, there had only been experiments on the bench. With its own enclosure, controls and connections, the S 602 was the first to become a finished piece of equipment.

Model 1 Preamplifier
1982. Dual mono. Still working.
The Burmester 808 was the spark. Model 1 went its own way, with a separate power supply, MM and MC phono, three line inputs and switched volume control. More than four decades later, it remains in use.
-
The Amp No. 1
80 watts. Quasi-complementary. MOSFET.
The starting point was not an audio circuit at all, but a high-current driver for stepper motors. Adapted for loudspeakers, the unusual topology became The Amp No. 1. Nearly four decades later, it still sounds remarkably right.
