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).
