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).

Features Tripath TA-2024 Integrated Circuit
15W/ch continuous power

Class D, aka Tripath, aka Class T, aka switching amps... whatever you want to call them, they have been nothing short of revolutionary across the field of audio technology. Class D amps are incredibly efficient and very clean sounding, but traditionally very low power. Because of their great efficiency they first took over in applications like mobile phones, TVs… anywhere a tiny, cool running low current amp was attractive. But then a very small, extremely cheap, amp marketed as a Class T amp came on the market and quickly developed a strong audiophile following around the world. Producing only a few watts per channel (rated at 15 WPC) this amp was a fantastic stand in for low power tube amps on high efficiency speaker systems. Since then, countless mods have been performed and new class D amplifier designs have begun showing up in the catalogs of high end audio manufacturers.

This amplifier uses the classic board that started it all. I’ve dressed it up in an aluminum enclosure, machined, painted, screen printed and assembled by hand right here in Brooklyn. We use my favorite connectors, including the same vintage style screw down speaker wire posts found on early Altec compression drivers. There’s no hocus pokus here. The classic, unmodified design, will blow anyone's mind for the price.

* If you want the cheapest way to power your speakers and you don’t care what it looks like, you can buy the same circuit board in a cheap plastic enclosure made by Dayton Audio. We will offer it here as well, just so no one can say we didn’t tell you about it.
