Our most complete high performance integrated digital hub
The Wadia S7i is the latest generation of our highly acclaimed series of high performance digital audio playback products. Fifteen years ago, Wadia was the first to develop proprietary digital circuitry that blended a CD player, preamplifier and digital processing in one product. Today the S7i platform not only provides reference quality CD playback, but also serves as a flexible and complete digital hub that manages and plays multiple digital sources.

A full complement of digital inputs including Wadia’s proprietary USB solution allows access and switching of a wide variety of digital sources. Superbly executed digital signal processing maintains the sonic integrity of the music and results in a more natural musical presentation. The digital to analog conversion is performed and the resulting current is driven with a Class A throughput stage maintaining time and phase integrity. Our patented digital volume control, noiseblock circuitry and true-balanced outputs optimize the signal for a wide range of systems. Advancements in power supply filtering and isolation result in quiet, pure power that allows instantaneous and accurate reproduction when it matters most.

The CD transport is at the heart of almost every Wadia product. Yet, only recently have we been able to co-design and fully collaborate on every single aspect of the mechanism, servo, buffer, firmware and critical transport components. This custom transport exceeds even our exacting standards and provides information extraction with the lowest measured error correction in Wadia’s history.

Once again, Wadia engineers, technicians and craftsmen have delivered the ultimate comprehensive high performance solution for managing and playing your digital sources.
