 DIGITAL

Wadii Digital Corporation was founded in 

1988, 

making it one of the oldest digital audio

companies in existence. Wadia was formed by a group of engineers from the Minneapolis-

based 3M Corporation (Minnesota Mining and Manufacturing) who had compiled many

years of experience in advanced digital and telecommunications research and development.

In the early 1980’s,  this group had become intrigued by the emerging CD technology.
Disappointed by the sound of early CD players, they examined the designs and found them
to be unsophisticated 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 home entertainment equipment.

Wadia's first product, the Wadia 2000 Decoding Computer, was a breakthrough.

For many listeners, it proved the viability of Compact Disc as a musically involving format.
Ever since, Wadia has continued to develop on the original technology; refining, listening
and improving along the way. Since the Wadia 2000, new generations of even higher
performance designs have been introduced. Each step of the way, Wodia has raised
the standard for performance of CD playback.

Here is an abbreviated list of the technological  innovations the Wadia engineers
have pioneered over the past 10 years:

First outboard Digital-to-Anolog  converter

DigiMaster  patented algorithm (filter optimized for reproducing music)

First company to apply glass fiber-optics to home audio

First company to recognize jitter as a source of audible distortion

First to perfect digital volume control

First high-end CD player competitive with expensive separates

ClockLink proprietary jitter reduction technology

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.

Now 

past our tenth year, Wadia continues to redefine the limits of digital music playback.

We are proud to introduce the Wadia 

27i 

a breakthrough in sonic performance

and a strong statement of our years of dedication to music.
