t Wadia we do not build
A
ordinary products. There are
enough of those. We do
build audio components that
inspire. We build with beauty
and fanatical attention to
detail. We are constructing
much more than a stereo.
We create moments of
exhilaration, freedom, and joy.
We provide our customers
with the ability to hear and
understand the universal
language of music.
In designing the series 9
Decoding Computer system
our objective was clear –
to create the new standard.
The 922 mono Decoding
Computers and the 931 Digital
Controller (series 9 Decoding
Computer system) present a
unique three box architecture
of unmatched digital and
analog technology. The 922
mono Decoding Computers
provide D>A conversion and
the 931 Digital Controller
functions as a digital
preamplifier. Combined with
the execution you expect
from reference Wadia, the
series 9 Decoding Computer
system is proof positive that
Wadia means – best in
digital audio reprodu ction.

igital Accuracy
D
The series 9 Decoding Computer system is quite simply the most resolving Wadia ever.
Three digital signal processors coupled with our most advanced up-sampling software,
DigiMaster™ 1.4, churn out an astounding 2.8224 million samples per second at a
theoretical 26 bits of resolution. DigiMaster allows us to generate this amazing amount
of data with accuracy both in the frequency and (particularly) in the time domain.
Why is this important? When accuracy in the time domain is achieved the resulting
3-dimensional sonic image leaves you with the uncanny feeling of being there.
Coherent Analog
In creating the Series 9 Decoding Computer system an all new pure Class A output
architecture was developed. To exploit the extraordinary data rate generated in the
digital section a discreet implementation of our patented SwiftCurrent™ technology
(SC-2D) was created. The output feeds directly into a phase accurate filter that
simultaneously creates voltage and removes unwanted high frequency noise. Analog
signals remain time and phase coherent as zero global feedback is maintained
throughout the entire system. The discreet analog signal path is musically pure.
Pure Power
The series 9 Decoding Computer system features a massive fully balanced quadruple
shielded toroidal transformer. There is an inductor filtered, fully regulated separate
power supply for digital processing, clocking, D>A conversion, and output stage.
The result – power response is immediate with lightning speed and instantaneous
reproduction of transient information.
Without Compromise
The 3 separate chassis have been machined out of high grade aluminum to create a
functional non-ferrous environment that acts as both a shield and a safe haven for
precision electronics. The look is powerful and yet refined – featuring a jewelry
grade finishing process requiring 5 separate steps to perfect. The 9 series Decoding
Computer system is built without compromise to have no equal.
Witness genius first hand, and your perceptions change. The series 9 Decoding
Computer system reveals the artist’s true intentions... Alter your Perception!
