Wadia Digital – a Brief History
Wadia Digital, founded in 1988, is one of the original companies dedicated to
high performance digital audio reproduction. Wadia was formed by a team of
engineers from the Minneapolis based 3M Corporation (Minnesota Mining and
Manufacturing) who shared many years of experience in advanced digital
telecommunications research and development. In the early 1980’s, these engineers
became intrigued by the emerging compact disc technology. Disappointed with
the sound quality of early CD players, they examined the workings and designs of
these early components and found them to be unsophisticated when compared
with the technology available in other areas of digital design. In response, they
founded Wadia Digital – a company based on the philosophy of applying advanced
technology to improve the performance of digital audio components. Wadia’s
first product, the Wadia 2000 Decoding Computer, was an absolute breakthrough
in digital audio. For many discerning listeners, it proved that Digital Audio was a
musically responsive, evolving, and engaging format.
Building on a tradition of excellence, Wadia continues to develop innovative
technology; refining, listening, engineering, and improving along the way. Since the
Wadia 2000, new generations of industry-leading designs have been introduced
and embraced by listeners around the world. Each step of the way, Wadia has
consistently raised the standard for performance of Digital Audio playback.

Here is a brief list of the technological innovations the Wadia engineers
have pioneered over the past 20 years:
• DigiMaster™ patented algorithm (filter optimized for reproducing music)
• ClockLink™ proprietary jitter reduction technology
• SwiftCurrent™ current to voltage conversion technology
• First outboard Digital-to-Analog converter
• First to apply glass fiber-optics to home audio
• First to recognize jitter as a source of audible distortion
• First to perfect digital volume control
• First high-end CD player competitive with expensive separates
•First company to provide bit perfect digital audio output from the iPod
While Wadia’s expertise and track record exceed those of most digital audio
companies, technology alone does not guarantee an immersive and captivating
musical performance. Wadia’s intuitive designs are born of a delicate balance
of technology shaped by a passion for music.
Wadia continues to re-define the limits of digital music playback. We are proud to
introduce the Wadia 151PowerDAC mini–abreakthrough in sonic performance
and a strong statement of our dedication to music.
