There are many S7i innovations, each of which is necessary, but not sufficient by itself, for proper performance.

It is the combination of all of these elements that allows the S7i to perform at such a high level.  It must be the digital hub that connects and manages all of your digital sources.  It must be a decoding computer that insures bit perfect digital to analog conversion.  It must connect directly to the power amplifier, and deliver a distinct improvement in sound quality.  And yes, it must play multiple disc formats including Red Book standard formats and FLAC data formats.

At the heart of the S7i is an exceptional new transport designed in collaboration with the Austrian company Stream Unlimited.  Wadia has a long history of using excellent CD transports, but the two-year collaboration with Stream Unlimited is the first time Wadia worked directly with a high-end digital transport company. The goal was to co-engineer an application-specific mechanism/servo system for Wadia playback machines.  We are convinced the new transport offers bit-perfect data retrieval well beyond the capacity of any prior Wadia machines.

The S7i utilizes two signal processors feeding a programmable gate array to form a powerful processing engine. Coupled with our patented DigiMaster 2.5 upsampling software, the S7i generates a data rate of 1.4112 million samples per second at 24 bits of resolution. DigiMaster allows us to generate this amazing amount of data with accuracy in the frequency and particularly in the time domain. ClockLink jitter reduction provides state-of-the-art audio information extraction from CDs and now Data CDs. A discreet implementation of our SwiftCurrent technology (SC-3D) was invented to exploit the extraordinary data rate generated in the digital section. Current exiting the converters is mirrored and driven with a zero global feedback Class A throughput stage. Signals remain time and phase coherent throughout the entire system. Why is this important? When accuracy in the time domain is achieved the resulting 3-dimensional sonic image leaves you with an uncanny suspension of disbelief.

 Our quest to reduce extraneous noise led to the inclusion of new multiple fully regulated digital power supplies.  The result is a measurable reduction in the noise floor. The adoption of additional inductor filtering for both the digital and analog power supplies of the main decoding circuit ensures smooth charging of capacitors and eliminating noise spikes from the ground plain. There is a fully regulated separate power supply for digital processing, clocking, D>A conversion, and the output stage.

Every performance component is powered by regulated isolated power traces. Silent pure power is delivered with lightning speed creating a sense of effortless, relaxed power.  

The S7i is a tour-de-force solution for any music lover wanting the very best single box integrated player/digital processor.
