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

Although Wadia’s digital expertise and track record exceed those of any 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 581se/781i CD Player, a breakthrough in sonic performance and value,
and a strong statement of our years of dedication to music.
