OJAS is the creative pen name of Devon Turnbull. As a university student studying Audio Engineering he started using the name across a variety of disciplines including graffiti, music, graphic design and clothing design. In 2003 Turnbull co-founded the clothing brand Nom de Guerre with Isa Saalabi, Wil Whitney and Holly Harnsongkram. For the next decade, while primarily working in fashion, the name OJAS was kept alive on sound sculptures Turnbull was crafting for himself and a growing number of audio enthusiasts around the world. With a particular interest in high efficiency speakers and low powered tube amplifiers, Ojas audio equipment aims to bring realistic, natural sound to the listener. These products are the result of two decades of experimentation, engineering and explorations in the audio underground.

The Nature of Sound


Sound is considered to be of two kinds, one a vibration of ether the other a vibration of air.
The vibration of ether which cannot be perceived in the physical sense, is considered the principle of all manifestation the basis of all substance the “music of the spheres” it forms permanent numerical patterns which are the basis of the worlds existence, this kind of vibration is not caused by physical shock as are audible sounds. It is therefore called anahata “unstruck”, the other kind of sound is an impermanent vibration of air, an image of the ether vibration. It is audible and always produced by a shock. It is therefore called ahata or “struck”.
Struck sound is said to give pleasure. Unstruck sound leads to liberation (Narada Purana).

ERG Media is proud to announce the forthcoming release of Jazz Kissa: The Soul of Japanese Listening Culture, an immersive photographic exploration of Japan’s iconic jazz cafés, known as Jazz Kissa. This book features a foreword by Devon Turnbull, connecting the philosophy of Jazz Kissa with today’s global resurgence of high-fidelity audio culture.

The book is the result of over fifteen years of dedicated work by photographer and cultural historian Katsumasa Kusunose, who has meticulously documented these intimate spaces and the people who keep their spirit alive.

The first cafés dedicated to playing recorded jazz opened in Japan in the late 1920s, reflecting the country’s early fascination with Western culture and music. Although many closed during World War II, the post-war period saw Jazz Kissa return in even greater numbers, spreading across Japan as quiet sanctuaries for dedicated listening.
These spaces preserve an almost spiritual relationship with sound—slow, immersive, and deeply intentional—in a world where music has become increasingly disposable and attention fragmented.

Each Jazz Kissa is built around rare vintage audio systems, towering speakers, and meticulously curated vinyl collections. Woven throughout the book is a special exploration of the design of the Hi-Fi equipment―from the legendary Altec A7s to iconic JBL speakers and bespoke amplifiers—revealing how the physicality of these machines shapes the emotional experience of listening. The aesthetic choices of these cafés are inseparable from the sound they produce, making them both temples of music and showcases of design excellence.

Printed on specially sourced Japanese paper inspired by the texture of
Altec A7 speakers and wrapped in a traditional OBI strip, Jazz Kissa is
both a cultural document and a beautiful object in its own right.
