At Wadia we do not build 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 921 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. Each 921 provides D>A conversion and the 931 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 the best in digital audio reproduction. Digital Accuracy  - 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? The time that it takes for a sound wave to reach one ear versus the other tells the listener where an object is located in space. 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 discrete implementation of our patented SwiftCurrent technology (SC-2D) was created. Current exiting the D>A converters is now optimally loaded, in turn allowing each DAC to remain linear. Current is then mirrored and driven with a zero global feed back Class A throughput stage. The output feeds directly into a phase accurate filter that simultaneously creates voltage and removes unwanted high frequency noise.The SC-2D generates 3 independent data streams that drive both the balanced and unbalanced legs of the Class A output stage. Analog signals remain time and phase coherent as zero global feedback is maintained throughout the entire system. Integrated Circuits that might introduce switching distortion have been eliminated. The discreet analog path is musically pure, nothing is included that does not contribute to performance.  Pure Power - The series 9 Decoding Computer system features a massive fully balanced quadruple shielded toroidal transformer.  Dual inductors ensure current flows smoothly and continuously to charge capacitors. There is a fully regulated separate power supply for digital processing, clocking, D>A conversion, and output stage. Every performance component is powered by dual regulated isolated power traces that join only at the ground plane.  The result – pure music power delivered 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 literally requiring 5 separate steps to perfect. The 9 series Decoding Computer system is built without compromise to have no equal. Alter your Perception! Witness genius first hand and your perceptions change.  The series 9 Decoding Computer system reveals the artist's true intentions.
