Brief History

Wadia was originally founded in 1988, making it one of the first high-end audio companies dedicated to digital audio. Wadia was formed by a group of engineers who were committed to using advanced digital technology to improve the performance of digital audio equipment.

Wadia’s first product, the Wadia 2000 Decoding Computer, was a breakthrough. For many listeners it proved the viability of the Compact Disc as a musically involving format. Since then Wadia has continued to develop new methods and technology. Each product resulted in a new standard of performance for digital audio decoding.

Here is an abbreviated list of the technological innovations Wadia engineers have pioneered:

First company to introduce an outboard Digital-to-Analog converter

First company to develop an audio optimized upsampling digital filter

First company to apply glass fiber-optics to home audio

First company to recognize clock-jitter as a source of audible distortion

First company to test and apply mechanical de-tuning to the development of audio component chassis design

First company to offer a CD perfect digital volume control

First company to develop a Direct to Digital Amplifier - PowerDAC

Patented DigiMaster™ upsampling algorithm, optimized for reproducing music

RocLock proprietary jitter reduction technology

ClockLink™ proprietary jitter reduction technology

SwiftCurrent™ zero-feedback current to voltage converter

DirectConnect system to connect digital audio products directly to an amplifier

Although Wadia’s digital expertise and track record exceed those of any other audio company, technology alone does not guarantee musical performance. Wadia designs are born of a delicate balance of technology shaped by a passion for music.

Wadia is proud to introduce the Wadia series 9 Decoding Computer System, a breakthrough in sonic performance and a strong statement of our years of dedication to music.
